Project Management
Libero IDE Design Flow
The Libero IDE Design Flow consists of six steps:
Step One - Design Creation
Plan out your design and use the Design Entry tools (such as SmartDesign) to enter it as either HDL (VHDL or
Verilog), structural schematic, or mixed-mode (schematic and RTL).
Step Two - Design Verification - Functional Simulation
After you have defined your design, you must verify that it functions the way you intended. After creating a testbench
using WaveFormer Pro, use the ModelSim VHDL or Verilog simulator to perform functional simulation on your
schematic or HDL design.
If you have an EDIF netlist created with the full version of ModelSim you can import the netlist into your project and
skip directly to Design Implementation (step four).
EDIF Flow Support - You can import an EDIF netlist in Project Manager. If you do not have HDL source files in
your project, the EDIF netlist is considered to be a source for the flow.
The name of your block as specified in the EDIF netlist is displayed in the Hierarchy under the work library and is
automatically Set as Root. The Project Flow Window is updated to show the EDIF flow: synthesis is unavailable and
you can go directly to Designer or to Simulation as you would do in the post-synthesis state of the regular HDL flow.
If you launch ModelSim, Project Manager automatically creates an HDL netlist.
The Configure Project Flow dialog does not allow you to activate synthesis.
As soon as you import an HDL Source file, the Hierarchy tab does not display the EDIF netlist any more and the
Project Flow Window is updated to show the regular HDL flow.
Note: Note: If you have a regular HDL project with a synthesized EDIF netlist and remove all the source files from
your project, the Project Design Flow will be changed to the EDIF flow and the EDIF netlist will appear in the
Design Hierarchy.
Step Three - Synthesis/EDIF Generation
Use Synplify Pro AE to generate your EDIF netlist. You can re-verify your design "post-synthesis" using the VHDL or
Verilog ModelSim simulator used in step two.
While all RTL code must be synthesized, pure schematic designs are automatically "netlisted" out via the Libero IDE
tools to create a structural VHDL or structural Verilog netlist.
Step Four - Design Implementation
After you have functionally verified that your design works, the next step is to implement the design using the Actel
Designer software. The Designer software automatically places and routes the design and returns timing information.
Use the tools that come with Designer to further optimize your design. Use SmartTime to perform static timing
analysis on your design, ChipEditor or ChipPlanner to customize your I/O macro placement, MultiView Navigator for
I/O customization, SmartPower for power analysis, and NetlistViewer to view your netlist.
12
Libero IDE v9.1 User’s Guide
Creating a New Libero IDE Project
Step Five - Timing Simulation
After you are done with design implementation, you can verify that your design meets timing specifications. After
creating a testbench using WaveFormer Pro, use the ModelSim VHDL or Verilog simulator to perform timing
simulation.
Step Six - Device Programming
Once you have completed your design, and you are satisfied with the timing simulation, create your programming file.
Depending upon your device family, you need to generate a Fuse, Bitstream, or STAPL programming file.

Project Sources
Project sources are any design files that make up your design. These can include schematics, HDL files, simulation
files, testbenches, etc. Anything that describes your design or is needed to program the device is a project source.
Source files appear in the Project Flow window. The Hierarchy tab displays the structure of the design modules as they
relate to each other, while the Files tab displays all the files that make up the project.
The design description for a project is contained within the following types of sources:
•
Schematics
•
HDL Files (VHDL or Verilog)
•
SmartDesign components
One source file in the project is the top-level source for the design. The top-level source defines the inputs and outputs
that will be mapped into the devices, and references the logic descriptions contained in lower-level sources. The
referencing of another source is called an instantiation. Lower-level sources can also instantiate sources to build as many
levels of logic as necessary to describe your design.
File Linking
The Project Manager enables you to link to files not managed in your Libero IDE project. Linked files are useful if you
want to preserve a file in an archive, or if more than one person is using a file and it is impractical to store it on your
local machine. If you link to external files and rename your project, the Project Manager asks if you want to copy the
external files into your project or continue using the link. Note that some files (such as schematics) cannot be linked.
Some project sources can be imported.
Sources for your project can include:

CoreConsole components include all the files needed by the Project Manager in your project folder. Libero IDE
lists the CoreConsole component in the Project Manager along with its files (each core includes its own block
symbol files, HDL source files, constraint files, implementation files, memory files, etc.).
•
When you import a CoreConsole component, the Project Manager creates a new directory in your project folder
called coreconsole that includes all the required CoreConsole files. Project Manager preserves the structure of the
original CoreConsole directory, except for the ViewDraw symbol - it gets copied into the viewdraw folder in
your project.

Libero IDE file types
When you create a new project in the Libero IDE Project Manager it automatically creates new directories and project
files. Your project directory contains all of your 'local' project files. If you import files from outside your current project,
the files must be copied into your local project folder. (The Project Manager enables you to manage your files as you
import them.)
Depending on your project preferences and the version of Libero IDE you installed, the Project Manager creates
directories for your project.
The top level directory (<project_name>) contains your PRJ file; only one PRJ file is enabled for each Libero IDE
project.
component directory - Stores your SmartDesign components (SDB and CXF files) for your Libero IDE project.
constraint directory - All your constraint files (SDC, PDC, GCF, DCF, etc.)
coreconsole directory - Default directory for all the CoreConsole files created in your Libero IDE project.
designer directory - ADB files (Actel Designer project files), -_ba.SDF, _ba.v(hd), STP, PRB (for Silicon Explorer),
TCL (used to run designer), impl.prj_des (local project file relative to revision), designer.log (logfile)
Note: Note: The Actel ADB file memory requirement is equivalent to 2x the size of the ADB file. If your computer
does not have 2x the size of your ADB file's memory available, please make memory available on your hard
drive.
hdl directory - all hdl sources. *.vhd if VHDL, *.v and *.h if Verilog
phy_synthesis directory - _palace.edn, _palace.gcf, palace_top.rpt (palace logfile) and other files generated by
PALACE
simulation directory - meminit.dat, modelsim.ini files
smartgen directory - GEN files and LOG files from generated cores

generated by the tools (not managed by Libero IDE)
viewdraw directory - viewdraw.ini files
Mixed-HDL Support in Libero IDE
You must have ModelSim PE or SE to use mixed HDL in the Libero IDE. Also, you must have Synplify Pro to
synthesize a mixed-HDL design.
When you create a project, you must select a preferred language. The HDL files generated in the flow (such as the
post-layout netlist for simulation) are created in the preferred language.
The language used for simulation is the same language as the last compiled testbench. (E.g. if tb_top is in verilog,
<fam>.v is compiled.)
If your preferred language is Verilog, the post-synthesis and post-layout netlists are in Verilog 2001. You cannot import
these netlists back into Designer; the Designer reader only accepts Verilog 95.
Saving Files
Files and projects are saved when you close them.
To save an active file:
•
From the File menu, choose Save or Save As.
•
Click the Save
button in the toolbar.
Saving Files in the Libero IDE Project Manager

HDL Templates in the Project Manager
HDL Templates in the Project Manager
Use the templates in the Libero IDE Project Manager to create HDL.
To use the templates included with the Project Manager, open your VHDL or Verilog file in the Project Manager text
editor. Right-click, and select Language Templates.
Place the cursor where you want to add the template, browse the list of VHDL and Verilog templates, and double-click
the template to add it to your design.
The VHDL and Verilog templates are useful if you want to modify your netlist but are unfamiliar with the language.
The templates facilitate the writing of HDL files by inserting predefined language constructs. You can also save your
own template files to reuse in other designs (for example, if you wanted to add the same header in all your files).
To create a user template:
•
Import an HDL file as a template, or
•
Save an open HDL file from the text editor as a template. To do so, right-click in the text editor and choose
Export as Template.

Designing with Designer Block Components
Designer Blocks (also generically called "components") enable you to partition a design and optimize critical sections.
You can reuse them later in new applications, ensuring consistent performance. Designing with blocks enables multiple
designers to work independently on parts of a single design.
Designer Block Advantages
•
You can focus on the timing of critical blocks and ensure the timing across the blocks meets requirements before
proceeding to the top-level flow.
•
Changes in other blocks have no impact on your own block, you can re-use your block without re-calculating the
timing.
•
The block can be re-used in multiple designs
•
Shorter verification time. You need to re-verify only the portion of the design that has changed.
Designer Block Features
•
You can create a Designer Block with or without I/Os.
•
A Designer Block can be synthesized, simulated, and placed-and-routed the same way as a regular design.
•
You can lock the place-and-route of the Designer Block to ensure performance does not change.
•
Performance and place-and-route can be fixed absolutely; however these rules can be relaxed gradually, if
necessary, to ensure that you can integrate the Designer Block into your <top> project.
•
You can use all the features in Designer Blocks in SmartDesign.
Use Designer Blocks When
•
The design is congested (uses 90% of the resources on a given die).
•
You have difficulty meeting timing by doing the design in its entirety. Blocks enable you to compartmentalize
the design and optimize sections before you optimize the entire design.
•
You want to re-use some elements of your design.
•
You want to use the identical elements multiple times in a single design.
You cannot use Designer Blocks with all families, they are family and die specific; if your Designer Block has I/Os it is
also package specific.
Supported families
IGLOO, ProASIC3, SmartFusion, Fusion, Axcelerator, and RTAX-S
Libero IDE v9.1 User’s Guide
59
Designing with Designer Block Components
Designer Blocks and Synthesis
You must run the synthesis tool in No I/O mode when you create your component. The Designer Block is not a full
design; Libero IDE sets this option for Synplify if you Enable Designer Block creation.
When you Publish a Designer Block, the Project Manager creates a timing shell that enables the synthesis tool to
better synthesize the <top> project. The timing shell is named <blockname>_syn.v(.vhd) if you are using Synplify or
<blockname>_pre.v(.vhd) if you are using Precision.
When you are working in your <top> project, the synthesis tool does not know how many globals you have in your
Designer Block, or if there will be clock sharing. The synthesis tool promotes as many globals as it can (e.g., four
globals for Axcelerator devices) and if you have globals in the Designer Block you will exceed the total number of
globals allowed in your device.
In this case, you must limit the number of globals added by the synthesis tool so that the total number (Designer Block
plus <top> project) does not exceed the number available on your device.
To add an internal global, you can use either the Synplify constraints editor (SCOPE) or an SDC file.
For example, to add a CLKINT after a CLK port, the command is:
define_attribute {n:CLK} syn_insert_buffer {CLKINT}

Creating a component in Designer
Creating a component in Libero IDE
Managing I/Os in a Designer Block Component
If you use I/Os in your Designer Block, use the following rules:
•
If the I/O is placed in the block, placement and VCCI of the I/O cannot be changed in the <top> design.
•
The register combining option cannot be changed in the <top> design.
•
Attributes and Vref pins can be changed if the values are legal (the I/O will not be unplaced).
Globals and Designer Block Components
You must manage your globals when creating a Designer Block to ensure that you have some available after you import
the Block into your <top> project.
There is no limit to the number of globals you can use in a Designer Block.
Global Sharing
You can share a global between the Designer Block and the <top> project. You must:
60
•
Use an internal global in the Designer Block.
•
Drive the global port in the <top> project with a global net.
Libero IDE v9.1 User’s Guide
Designer Block Compile Report
Libero IDE removes the internal global and re-routes the entire net.
You can use other global macros in the Designer Block, but you cannot share them with the <top> project.
Global Sharing with IGLOO, ProASIC3, SmartFusion and Fusion - Use CLKINT in the Designer Block to share
the global in the component with the <top> project.
Global Sharing with Axcelerator and RTAX-S - Use CLKINT and HCLKINT in the Designer Block to share the
global in the component with <top> project. Also, you must drive HCLKINT within the Designer Block with an
HCLK net in the <top> project; and drive CLKINT in the Designer Block with a RCLK in the <top> project.
See the list of Physical Design Constraint (PDC) files for more information on how to assign constraints.
Local Clock
You can use local clocks in your component to save on globals, but you may need to do some floorplanning in your
<top> project.
For example, if you are using an Axcelerator device: if you have one local clock in the Designer Block of type RCLK
and four RCLK macros in the <top> project, the Prelayout checker fails. You must floorplan the project to restrict the
load placement of one of the clocks in the <top> project.
Limitations
When you create your block, you cannot assign a port-connected net to a local clock.
The routing for local clocks from the blocks cannot always be preserved.
For Axcelerator all local clocks will be rerouted in the <top> design.
For all other families, local clocks are rerouted only if they are used in more than one block. The local clock constraint
is preserved and the only difference in the routing is from the driver to the entry point of the clock network (when it
gets to the clock network you end up with the same routing since the macros are locked in the same location).
Designer Block Compile Report
If you instantiate Designer Blocks in your design, the Compile report includes a description of the blocks you used.
The report appears in the Designer Log window after Compile is complete.
The report lists the name of the module, the name of the instance, the number of macros and nets used in the blocks,
and information on how conflicts between blocks were resolved by the Compile options or PDC commands (if any).
For example:

Designer Block Component Limitations
If you instantiate the same Designer Block many times in the <top> design, only the first instance retains the placeand-route information (if it has any); the others do not. Only the netlist is preserved.
To preserve the relative placement and routing of other blocks you must move the blocks using a PDC command. This
PDC file must be imported as a source file along with the netlist(s) and CDB files. If possible, routing is preserved
when you move the blocks with a PDC command.
See the move_block PDC command for more information.
Note: Note: Axcelerator and RTAX-S routing is not preserved when you move a block.

regular Libero IDE designs. There is no limit to the number of CXF files you can import, but you cannot import the
same Designer Block more than once, and the family and device for your imported block must match your project.
After you import the CXF file, the Project Manager displays the imported files in the Design Hierarchy tab.
The Designer Block(s) you instantiate must have the same family and die (and package, if it contains I/Os) as your
current <top> project. If the family, die, and package do not match, Libero IDE asks if you want to change the current
setting to match the one from the Designer Block.
The Project Manager passes all the Designer Block files to Designer automatically.
Note: Note
•

Designer Block Component PDC Commands
Creating a Block
The Designer-Block specific PDC command set_port_block enables you to remove an I/O connected to a component
port and add a buffer before or after a component port to limit the fanout of the port net. The command applies only to
the selected port.
The tribuf and bibuf I/Os cannot be removed.
Adding a buffer enables more precise Designer Block timing, since the nets driving ports are not preserved when the
Designer Block is generated/published.
Instantiating a Block
The following PDC commands manage conflict resolution between blocks. Each command is specific to an instance of
a block.
•
move_block - Moves Designer Blocks from their original locked placement by preserving the relative placement
between the instances. You can move them left, right, up or down.
68
Libero IDE v9.1 User’s Guide
Floorplanning a Designer Block
•
set_block_options - Overrides the compile option for placement or routing conflicts for either a specific block or
an instance of a block.
Floorplanning a Designer Block
Actel recommends that you floorplan your Designer Block component (in MVN or with PDC commands) to ensure
that your Designer Block is placed in a specific region. If you do not restrict your Designer Block placement, it may be
placed anywhere on your die; see the define_region PDC command.
It is also important to consider the placement of all interface macros in the boundaries of these regions. This facilitates
the interconnection of the Designer Block to the top-level design. If the Designer Block is highly optimized (densely
packed) there may be no routing channels available to connect to any internal Designer Block interface macro. Placing
all interfaces at Designer Block boundaries helps you eliminate routability issues, routing congestion, and failure.
Designer-Block specific features in MVN are:
•
Block Ports tab - Lists all the ports in a Designer Block even if they are not connected to I/Os.
•
Interface Instances in Designer Block creation (in the Active Lists) - Lists all macros connected to ports. These
macros must be placed on the boundary of your Designer Block region, since they will be connected to the <top>
design.
•
Designer Block content available when you instantiate a Designer Block in the <top> design (in Active Lists) Lists all macros in the Designer Block.
•
A block tab that lists all the blocks in your design.
•
Search support that enables you to find a specific block in your design.
•
Show the routing of locked nets from the Designer Blocks immediately after compile is complete; no need to
wait until layout is finished since the routing is locked and will not be changed.
Generate a Designer Block Component in Designer
When you finish Compile and Layout, click Generate Block to create your Designer Block files.
When you publish your Designer Block, Designer creates a netlist file (*.v; *.vhd), info file for Libero IDE (*.cxf),
Designer Block file (*.cdb), and report files.
Libero IDE uses the CXF file to manage and audit the Designer Block in your project. The CDB file contains all your
design information for the Designer Block.
You can edit your Designer Block later; just open the design, make your changes, and re-create.

To export a CDB file, from the File menu, choose Export > Netlist Files and for the Save as type, choose Actel CDB
files (*.cdb). The exported CDB file is identical to the original imported CDB file.
If you export a Designer Block that contains multiple CDB files, the exported files are identical to the original
imported CDB files.
If your design contains many CDB files, the block name is added as a suffix to the specified filename; the names of all
exported files are listed in the Log window. For example:
Wrote to files:

If some instances get unplaced for any reason, the non-conflicting elements
remaining are preserved but not locked (you can move them).
LOCK
If some instances get unplaced for any reason, the remaining non-conflicting
elements are preserved and locked.
Routing

ERROR
Description
Compile errors out if any preserved net routing in a designer block is deleted.
RESOLVE If a nets' routing is removed for any reason, the routing for non-conflicting nets is
also removed. In other words, if there are any conflicts, no routing from the block
is kept
KEEP
If a nets routing is removed for any reason, the routing for the non-conflicting nets
is preserved but not locked (so that they can be rerouted).

You can drag configured cores onto a Canvas where they are viewed as blocks in a functional block diagram. From the
Canvas you can:
•
Make connections between your blocks
•
View individual connection details
•
Show or hide individual nets
•
Set or clear attributes (such as Invert, Tie Low, Tie High, or Tie Open)
•
Add slices
•
Move, duplicate, or delete blocks
•
Add notations such as labels, shapes, lines, or arrows to document your design
•
Auto-stitching interfaces and other connections (such as AMBA)
•
Memory Map / Datasheet - The datasheet reports the memory map of the different subsystems of your design,
where a subsystem is any independent bus structure with a Master and Slave peripheral attached.
SmartDesign supports all Actel product families.
SmartDesign Design Flow
SmartDesign enables you to stitch together design blocks of different types (HDL, IP, etc ) and generate a top-level
design. The Files tab lists your SmartDesign files in alphabetical order.
You can build your design using SmartDesign with the following steps:
Step One – Instantiating components: In this step you will add one or more building blocks, HDL modules,
components, and schematic modules from the project manager to your design. The components can be Designer
blocks, cores generated from the core Catalog, and IP cores.
Step Two – Connecting bus interfaces: In this step, you can add connectivity via standard bus interfaces to your design.
This step is optional and can be skipped if you prefer manual connections. Components generated from the Catalog in
Project Manager may include pre-defined interfaces that allow for automatic connectivity and design rule checking
when used in a design.

SmartDesign
Step Three – Connecting instances: The Canvas allows you to create manual connections between ports of the
instances in your design. Unused ports can be tied off to GND or VCC (disabled); input buses can be tied to a
constant, and you can leave an output open by marking it as unused.
Step Four – Validating the SmartDesign component: Verify the connectivity of your design using the Design Rules
Check. This feature opens a special grid where design errors and warnings are organized by type and message. You can
fix the errors and warnings directly in the grid. You must run the Design Rules Check again after you make your
connections to check for new errors and warnings.
Step Five – Generating the SmartDesign component: In this step, you generate a top-level (Top) component and its
corresponding HDL file. This component can be used by downstream processes, such as synthesis and simulation, or
you can add your SmartDesign HDL into another SmartDesign.
You can save your SmartDesign at any time.
Using Existing Projects with SmartDesign
You can use existing Libero® Integrated Design Environment (IDE) projects with available building blocks in the
project to assemble a new SmartDesign design component. You do not have to migrate existing top-level designs to
SmartDesign and there is no automatic conversion of the existing design blocks to the SmartDesign format.
Note: Note: Cores used in previous versions of software will work in SmartDesign, but they will NOT include
standard bus interfaces if they are available. Bus interfaces (BIFs) can be recovered by regenerating the core in
the latest software.
Note: Examples of cores with standard BIFs: ASB, Flash Memory System Builder, VRPSM, AMBA DirectCore(s),
and similar.

General Questions
What is SmartDesign?
SmartDesign is a design entry tool. It’s the first tool in the industry that can be used for designing System on a Chip
designs, custom FPGA designs or a mixture of both types in the same design. A SmartDesign can be the entire FPGA
design, part of a larger SmartDesign, or a user created IP that can be stored and reused multiple times. It’s a simple,
intuitive tool with powerful features that enables you to work at the abstraction level at which you are most
comfortable.
It can connect blocks together from a variety of sources, verify your design for errors, manage your memory map, and
generate all the necessary files to allow you to simulate, synthesize, and compile your design.
How do I create my first SmartDesign?
From the Project Manager Project Flow window, in the Design Entry Tools section, click the SmartDesign icon:

For basic inversion of pins, you can right-click a pin and choose Invert. An inverter will be placed at this pin when the
design is generated. You can also right-click a pin and choose Tie Low or Tie High if you want to connect the pin to
either GND or VCC.
To tie an input bus to a constant, right-click the bus and choose Tie to Constant. To mark an output pin as unused,
right-click the pin and choose Mark as Unused.
To clear these, just right-click on the pin again and choose Clear Attribute.
My logic is a bit more complex than inversion and tie offs - what else can I do?
You have full access to the Actel library macros, including AND, OR, and XOR logic functions. These are located in
the Project Manager Catalog, listed under Actel Macros. Drag the logic function you want onto your SmartDesign
Canvas.
How do I create a new top level port for my design?
You can right-click either of the top level blocks (gray blocks on the left and right of the Canvas space). Right-click the
block on the far left of your Canvas (this represents the top level of your design) and choose Add Port.
How do I rename one of my instances?
Double-click the instance name on the Canvas and it will become editable. The instance name is located directly above
the instance on the Canvas.
How do I rename my top level port?
Right-click the port you want to rename and choose Modify Port.

How do I connect my peripherals to the bus?
Make sure you have the proper bus core that is compatible with your peripheral instantiated in the design. Click Auto
Connect and SmartDesign will automatically form the connections.
But I need my peripheral at a specific address or slot.
Right-click the Canvas and choose Modify Memory Map to invoke the Modify Memory Map dialog that enables you
to set a peripheral to a specific address on the bus.
The bus core will show the slot numbers on the bus interface pins. These slot numbers correspond to a memory address
on the bus.
Verify that your peripheral is mapped to the right bus address by viewing your design’s Memory Map.
How do I view the Memory Map of my design?
In the Project Manager menu bar, choose SmartDesign > Show Memory Map/Data Sheet. This creates a datasheet of
your design, including the pin out, cores used, and memory map.
The memory map section will also show the memory details of each peripheral, including any memory mapped
registers.
How do I simulate my processor design?
SmartDesign automatically generates the necessary Bus Functional Model (BFM) scripts required to simulate your
processor based design. A top level testbench for your SmartDesign is generated automatically as well.
Create your processor design, generate it, and you will be able to simulate it in ModelSim.
I have my own HDL block that I want to connect as a peripheral on the AMBA bus. How can I do that?
If your block has all the necessary signals to interface with the AMBA bus protocol ( ex: address, data, control signals)
then:
1.
In the Project Manager Catalog (inside the Bus Definitions tab), find the AHB or APB slave interface.
2.
Drag this bus definition onto your instance on the Canvas. A dialog box opens, asking you to map the signals on
your instance to the required bus definition signals. Complete this mapping and click OK.
Now your instance has a proper AMBA bus interface on it. You can manually connect it to the bus or let Auto
Connect find a compatible connection.

Making your Design Look Nice
Can the tool automatically place my instances on the Canvas to make it look nice?
Yes. Right-click the Canvas white space and choose Auto Arrange Instances.
My design has a lot of connections, and the nets are making my design hard to read. What do I do?
You can disable the display of the nets in the menu bar (Canvas > Nets). This automatically hides all the nets in your
design.
You can still see how pins are connected by selecting a connected pin, the net will automatically be visible again.
You can also selectively show certain nets, so that they are always displayed, just right click on a connected pin and
choose Show Net.
My instance has too many pins on it; how can I minimize that?
Try grouping functional or unused pins together. For example, on the CoreInterrupt there are 8 FIQSource* and 32
IRQSource* pins, group these together since they are similar in functionality.
To group pins: Select all the pins you want to group, then right-click one of the pins and choose Add pins to group.
If a pin is in a group, you are still able to use it and form connections with it. Expand the group to gain access to the
pin.
Oops, I missed one pin that needs to be part of that group? How do I add a pin after I already have the group?
Select the pin you want to add and the group pin, right-click and choose Add pins to <name> group.
I have a pin that I don’t want inside the group, how do I remove it?
Right-click the pin and choose Ungroup selected pins.
How can I better see my design on the Canvas?
There are zoom icons in the toolbar:
From left to right, they are: Zoom in, Zoom out, Zoom to fit, and Zoom range. You can also maximize your
workspace with CTRL-W.

If your design contains standard Bus Instances such as the DirectCore AMBA bus cores, CoreAPB or CoreAHB, then
you can view the Memory Map Configuration of your design. To do so, from the SmartDesign menu, choose Show
Memory Map / Data Sheet.
The design’s memory map is determined by the connections made to the bus component. A bus component is divided
into multiple slots for slave peripherals or instances to plug into. Each slot represents a different address location and
range to the Master of the bus component.
Libero IDE v9.1 User’s Guide
89
Getting Started with SmartDesign
The datasheet reports the memory map of the different subsystems of your design, where a subsystem is any
independent bus structure with a Master and Slave peripheral attached.
Connecting peripherals to busses can be accomplished using the normal SmartDesign connectivity options:
•
Auto-Connect - the system finds compatible bus interfaces and connects them together
•
The Modify Memory Map dialog box
•
Canvas - Make connections between your blocks.
•
Finding compatible bus interfaces
Your application and design requirements dictate which address location (or slots) is most suitable for your bus
peripherals. For example, the memory controller should be connected to Slot0 of the CoreAHB bus because on Reset,
the processor will begin code execution from the bottom of the memory map.
The Memory Map View opens your default web browser to display the memory map information. An example is
shown in the figure below.

Convert CoreConsole Components
Your project contains components that were created by CoreConsole. CoreConsole is being replaced by SmartDesign,
which incorporates the same functionality with enhanced features.
Actel recommends that you upgrade and convert your design.
The converted SmartDesign and/or IP Component is fully equivalent in terms of peripheral configuration and
connectivity. In addition, your instance, port, and net names are preserved.
When you transition to SmartDesign, your CoreConsole design is converted to a SmartDesign and opened on the
SmartDesign Canvas. You must regenerate your SmartDesign component after you transition from CoreConsole.
Libero IDE v9.1 User’s Guide
91
Getting Started with SmartDesign
Converting your component requires a re-synthesis of your design. If you have already completed your design and
validation phase and are satisfied with your design then you can choose to continue using CoreConsole.
In SmartDesign you can drag configured cores onto the Canvas where they are viewed as blocks in a functional block
diagram. From the Canvas you can:
•
Make connections between your blocks
•
Easily instantiate and connect HDL, Design Block (non-IP Catalog cores), and Actel macros
•
View individual connection details
•
Show or hide individual nets
•
Set or clear attributes (such as Invert, Tie Low, Tie High, or Tie Open)
•
Add slices
•
Move, duplicate, or delete blocks
•
Add notations such as labels, shapes, lines, or arrows to document your design
•
Auto-stitching interfaces and other connections (such as AMBA)
•
Memory Map / Datasheet - The datasheet reports the memory map of the different subsystems of your design,
where a subsystem is any independent bus structure with a Master and Slave peripheral attached.
In certain situations, conversion may not produce a fully equivalent design. In this case, the following message appears
in the log window:
Warning: A bus interface ‘<bus interface>’ was found at the top level of component ‘<design>’, the converted design
may have different top level ports related to this bus interface. Please check your converted design.
This occurs because CoreConsole and SmartDesign have different rules when connecting bus interfaces to the top
level. The design is still functionally the same, except it may have differently named ports related to that bus interface
and you may have extra ports related to that bus interface. The extra ports are due to the fact that SmartDesign creates
unique output ports in the bus interface even if they are connected to the same pin internally.
See the SmartDesign FAQ for more information on basic operations in CoreConsole and their SmartDesign
equivalent. SmartDesign also has specific support for working with processor-based designs.
What to do if Conversion Fails
If core(s) contained in the CoreConsole project are not downloaded into your vault: You must download these cores
into your vault and rerun the conversion. See the Catalog help topic for more information on downloading cores.
If core(s) contained in the CoreConsole project are using the legacy IP-XACT loose generator interface (LGI) that is
no longer supported: Once the new versions of these cores are available, you can substitute the new version in your
CoreConsole project and rerun the conversion. To rerun the conversion, close and reopen your Libero IDE project.

Canvas Overview
The SmartDesign Canvas is like a whiteboard where functional blocks from various sources can be assembled and
connected; interconnections between the blocks represent nets and busses in your design.
You can use the Canvas to manage connections, set attributes, add or remove components, etc. The Canvas displays all
the pins for each instance (as shown in the figure below).
The Canvas enables you to drag a component from the Hierarchy, Files list, or a core from the Catalog and add an
instance of that component or core in the design. Some blocks (such as Basic Blocks) must be configured and generated
before they are added to your Canvas. When you add/generate a new component it is automatically added to your
Hierarchy.
To connect two pins on the Canvas, select any two pins on the Canvas (Ctrl + click to select a pin), right-click one of
the pins you selected and choose Connect. The Connect is disabled if you attempt to illegally connect two pins.
Click the Maximize Work Area button
to hide the other windows and show more of the Canvas. Click the
button again to return the work area to the original size.
The Canvas displays bus pins with a + sign (click to expand the list) or - (click to hide list). If you add a slice on a bus
the Canvas adds a + to the bus pin.
Components can be reconfigured any time by double-clicking the instance on the Canvas. You can also add bus
interfaces to instances using this view. In the Canvas view, you can add graphic objects and text to your design.

affect only the Canvas view; other SmartDesign views and the underlying design are not affected by the pin groups.
Grouping pins enables you to:

If your design becomes too cluttered:
1.
Hide the display of nets by de-selecting Canvas > Nets. This hides all the scalar and bus nets on your Canvas.
You can also right-click a pin and choose Show Net (or Hide Net) to show/hide individual nets. Note that
selecting a pin will make the corresponding net temporarily visible.
2.
Group your pins. It may help to group pins that are functionally similar, or to group pins that are already
connected or will be unused in your design.
To further customize your design's appearance:
1.
Double-click the names of instances to add custom names. For example, it may be useful to rename an instance
based on a value you have set in the instance: the purpose of an instance named 'array_adder_bus_width_5' is
easier to remember than 'array_adder_0'.

Grid
Grid
Grid Overview
The Grid (see image below) provides a mechanism for making manual connections between building blocks in your
design. The grid displays your design in a spreadsheet for sorting and filtering, enabling you to quickly access and
manipulate any subset of your design.
The Grid shows block instances vertically and horizontally on the spreadsheet, such that the port rows on the
spreadsheet intersect with port columns. Each intersection of rows and ports on the spreadsheet provides a connection
opportunity.
The grid is divided into two panels, the Display panel and the Connection panel.
The Grid offers two different views: the Instance-Instance view and the Net-Instance view. The behavior of the two
panels is the same in both views.
The default display of the Grid shows connections between all the instances in your design in an Instance-Instance
view.
Actel recommends that you work with only a subset of the instances in the current design when making manual
connections. This greatly reduces the information displayed in the Grid view and makes it easier to create manual
connections.
Click the Maximize Work Area button
to hide the other windows and show more of the Grid.
To create new Grids with just a subset of instances, select the instances between which you are making connections on
the Canvas, then right-click and choose Edit Connections. A new Grid will be displayed, with only those instances and
the top-level. When you are done making connections, right-click the grid view name tab and close the subset view.
To further simplify the data search in the grid and to make connections efficiently, use Filtering, Hierarchical sort in
the instance-instance view, and the find unconnected ports (Hide All Connected Ports) features.

Making driver and bus interface pins unused
Driver or bus interface pins can be marked unused (floating/dangling) if you do not intend to use them as a driver in
the design. If you mark a pin as unused the Design Rules Check does not return Floating Driver or Unconnected Bus
Interface messages on the pin.
Once a pin is explicitly marked as unused it cannot be used to drive any inputs. The unused attribute must be explicitly
removed from the pin in order to connect it later. To mark a driver or bus interface pin as unused:
•
Right-click the driver or bus interface pin and choose Mark as Unused
•
In the Grid Attribute column, click the attribute and select Mark as Unused

Automatic Connections
Using automatic connections (as shown in the figure below) enables the software to connect your design efficiently,
reducing time required for manual connections and the possibility of introducing errors.
To auto connect the bus interfaces in your design, right-click the design Canvas and select Auto Connect, click the
Auto Connect button
; or from the SmartDesign menu, choose Auto Connect.
You can select individual pins or groups on the Canvas to auto-connect. Select the pins, right-click and choose Auto
Connect.
SmartDesign searches your design and connects all compatible bus interfaces.
SmartDesign will also form known connections for any SoC systems such as the processor CLK and RESET signals.
If there are multiple potential interfaces for a particular bus interface, Auto Connect will not attempt to make a
connection; you must connect manually. You can use the Canvas, Grid or the Find Compatible Bus Interface dialog
box to make the manual connection.

Manual Connections
To make manual connections between to pins on the Canvas, select both pins (use CTRL + click), right-click either
pin and choose Connect. If the pins cannot be legally connected the connection will fail.

Deleting Connections
Deleting Connections
To delete a net connection on the Canvas, click to select the net and press the Delete key, or right-click and choose
Delete.
To remove all connections from one or more instances on the Canvas, select the instances on the Canvas, right-click
and choose Clear all Connections. This disconnects all connections that can be disconnected legally.
You can also select one or more rows in the Grid and choose Remove Connections from Selected Ports from the rightclick menu to remove the connects for a group of Ports.
If you click in a cell displaying a connection, selecting Disconnect from the drop down removes just that connection.
Certain connections to ports with PAD properties cannot be disconnected. PAD ports must be connected to a design’s
top level port. PAD ports will eventually be assigned to a package pin. In SmartDesign, these ports are automatically
promoted to the top level and cannot be modified or disconnected.
Top-level Connections
Connections between instances of your design normally require an OUTPUT (Driver Pin) on one instance to one or
more INPUT(s) on other instances. This is the basic connection rule that is applied when connecting.
However, directions of ports at the top level are specified from an external viewpoint of that module. For example, an
INPUT on the top level is actually sending (‘driving’) signals to instances of components in your design. An OUTPUT
on the top level is receiving (‘sinking’) data from a Driver Pin on an internal component instance in your SmartDesign
design.
The implied direction is essentially reversed at the top-level. Making connections from an OUTPUT of a component
instance to an OUTPUT of top-level is legal.
This same concept applies for bus interfaces; with normal instance to instance connections, a MASTER drives a
SLAVE interface. However, they go through a similar reversal on the top-level.

About Bus Interfaces
A bus interface is a standard mechanism for specifying the interconnect rules between components or instances in a
design. A bus definition consists of the roles, signals, and rules that define that bus type. A bus interface is the
instantiation of that bus definition onto a component or instance.
The available roles of a bus definition are master, slave, and system.
A master is the bus interface that initiates a transaction (such as read or write) on a bus.
A slave is the bus interface that terminates/consumes a transaction initiated by a master interface.
A system is the bus interface that does not have a simple input/output relationship on both master/slave. This could
include signals that only drive the master interface, or only drive the slave interface, or drive both the master and slave
interfaces. A bus definition can have zero or more system roles. Each system role is further defined by a group name.
For example, you may have a system role for your arbitration logic, and another for your clock and reset signals.
Mirror roles are for bus interfaces that are on a bus core, such as CoreAHB or CoreAPB. They are equivalent in signal
definition to their respective non-mirror version except that the signal directions are reversed.
The diagram below is a conceptual view of a bus definition.

The Catalog in the Project Manager contains a list of Actel-specific and industry standard bus definitions, such as
AMBA.
You can add bus interfaces to your design by dragging the bus definitions from the Bus Definitions tab in the Catalog
onto your instances inside SmartDesign.
Some Actel cores have bus interfaces that are instantiated during generation.
Certain bus definitions cannot be instantiated by a user. Typically these are the bus definitions that define a hardwired
connection and are specifically tied to a core/macro. They are still available in the catalog for you to view their
properties, but you will not be able to add them onto your own instances or components. These bus definitions are
grayed out in the Catalog.
A hardwired connection is a required silicon interconnect that must be present and specifically tied to a core/macro.
For example, when using the Real Time Counter in a Fusion design you must also connect it to a Crystal Oscillator
core.
Maximum masters allowed - Indicates how many masters are allowed on the bus.
Maximum slaves allowed - Indicates how many slaves are allowed on the bus.
Default value - indicates the value that the input signal will be tied to if unused. See Default tie-offs with bus
interfaces.
Required connection - Indicates if this bus interface must be connected for a legal design.
Hover your mouse over a bus definition in the Project Manager Bus Definition Catalog to view the
masters/slave/default/required connection information.

Bus Interface Details
Bus Interface Name: Name of bus interface.
Instance Name: Specifies the name of the instance.
Bus Definition: Specifies the name of the bus interface.
Role: Specifies the bus role (master or slave).
Vendor: Specifies the vendor for the bus interface.
Version: Specifies the version for the bus interface.
Configuration Parameters
Certain bus definitions contain user configurable parameters.
Libero IDE v9.1 User’s Guide
135
Bus Interfaces
Parameter: Specifies the parameter name.
Value: Specifies the value you define for the parameter.
Consistent: Specifies whether a compatible bus interface must have the same value for this bus parameter. If the bus
interface has a different value for any parameters that are marked with consistent set to yes, this bus interface will not
be connectable.
Signal Map Definition
The signal map of the bus interface specifies the pins on the instance that correspond to the bus definition signals. The
bus definition signals are shown on the left, under the Bus Interface Definition. This information includes the name,
direction, width, and required properties of the signal.
The pins for your instance are shown in the columns under the Component Instance. The signal element is a dropdown list of the pins that can be mapped for that definition signal. Only pins that have the same direction and width
requirements will be shown.
If the Req field of the signal definition is Yes, you must map it to a pin on your instance for this bus interface to be
considered legal. If it is No, you can leave it unmapped.
If the Width field is Any there is no restriction on the width for this definition signal. That means a pin of any width
on your instance can be mapped to this signal. During bus interface connection, if the instance pins are of differing
widths, the bit connections will start from right to left. For example, if a 16-bit bus is connected to an 8-bit bus, the 8bit bus will be connected to bits 7 down to 0 of the 16-bit bus. The higher bits will be unmapped and tied off at
generation time.
Modifying Bus Interface Details
Only bus interfaces that you explicitly added to an instance can be modified. Bus interfaces that were instantiated as
part of core generation cannot be modified.
To modify the properties of a bus interface:

no compatible bus interface is generated; you will be given the opportunity to reconfigure the core in this
scenario.
Actel Bus Interfaces
The Catalog provides the following Actel-specific bus interfaces:
ExtSeqCtrl
This bus interface defines the set of signals required to interface to the Analog System External Sequence Control. If
the Analog System is configured with more than a single procedure, it will export this bus interface. Your own logic
would need to connect to this bus interface to properly communicate and control the sequencer.
138
Libero IDE v9.1 User’s Guide
Actel Bus Interfaces
RTCXTL
This bus interface represents the hardwired connection needed between the Real Time Counter and the Crystal
Oscillator.
RTCVR
This bus interface represents the hardwired connection needed between the Real Time Counter and the Voltage
Regulator Power Supply Monitor.
InitCfg
This is the initialization and configuration interface that is generated as part of the Flash Memory Builder. Any clients
can be initialized from the Flash Memory as long as it can connect to this bus interface. This is for pure initialization
clients that do not require save-back to the Flash Memory.
InitCfgSave
This is the initialization and configuration interface that is generated as part of the Flash Memory Builder. Any client
can be initialized or saved-back to the Flash Memory as long as it can connect to this bus interface. This is for clients
that require initialization and save-back capabilities to the Flash Memory.
InitCfgCtrl
This interface is used to initiate the save-back procedure of the Flash Memory.
InitCfgAnalog
This interface is required between the Flash Memory System and the Analog System core.
FlashDirect
This bus interface defines the set of signals that are required to interface directly to the Flash Memory. From the Flash
Memory, if you add a data storage client, this interface will be exported. Interfacing to this interface enables direct
access to the Flash Memory.
XTLOscClk
This interface represents the Crystal Oscillator clock.
RCOscClk
This interface represents the RC Oscillator clock.
Libero IDE v9.1 User’s Guide

DirectCore Bus Interfaces
The Catalog provides the following DirectCore bus interfaces.
AHB
The AMBA AHB defines the set of signals for a component to connect to an AMBA AHB or AHBLite bus. The bus
interface that is defined in the system is a superset of the signals in the AHB and AHBLite protocol. You can use the
AHB bus interface in the bus definition catalog to connect your module to an AHB or AHBLite bus.
APB
The AMBA APB defines the set of signals for a component to connect to an AMBA APB or APB3 bus. The bus
interface that is defined in the system is a superset of the signals in the APB and APB3 protocol. You can use the APB
bus interface in the bus definition catalog to connect your module to an APB or APB3 bus.
SysInterface
The SysInterface is the interface used between the CoreMP7 and CoreMP7Bridge cores.
DBGInterface
This is the set of debug ports on the CoreMP7 core.
CPInterface
This is the co-processor interface on the CoreMP7 core.
Exposing Bus Interface Pins
Pins that are contained as part of a bus interface will automatically be filtered out of the display. These ports are
considered to be connected and used as part of a bus interface.
However, there are situations where you may wish to use the ports that are part of the bus interface as an individual
port, in this situation you can choose to expose the pin from the bus interface.
To expose pins in a Bus Interface:
1.
Select a bus interface port, right-click, and choose Expose Bus Interface Pins. The Expose Bus Interface Pin
dialog box appears (as shown below).
140
Libero IDE v9.1 User’s Guide
Default Tie-offs with Bus Interfaces
Figure 61 · Expose Driver Pin Dialog Box
2.
Click the checkbox associated with the driver pin you want to expose. Once the port is exposed it appears in the
Grid and is available for individual connection.
Note: Note: If you have already connected the bus interface pin, then you will not be able to expose the nondriver pins. They will be shown grayed out in the dialog. This is to prevent the pin from being driven by
two different sources.
To un-expose a driver pin, right-click the exposed port and choose Hide Bus Interface Pin.
Default Tie-offs with Bus Interfaces
Bus definitions can contain default values for each of the defined signals. These default values specify what the signal
should be tied to if it is mapped to an unconnected input pin on the instance.
Bus definitions are specified as required connection vs optional connection that defines the behavior of tie-offs during
SmartDesign generation.
Required bus interfaces - The signals that are not required to be mapped will be tied off if they are mapped to an
unconnected input pin.
Optional bus interfaces - All signals will be tied off if they are mapped to an unconnected input pin.
Tying Off (Disabling) Unused Bus Interfaces
Tying off (disabling) a bus interface sets all the input signals of the bus interface to the default value.
To tie off a bus interface, right-click the bus interface and select Tie Off.
This is useful if your core includes a bus interface you plan to use at a later time. You can tie off the bus interface and it
will be disabled in your design until you manually set one of the inputs.
Libero IDE v9.1 User’s Guide
141
Bus Interfaces
Some bus interfaces are required; you cannot tie off a bus interface that is required. For example, the Crystal Oscillator
to RTC (RTCXTL) bus interface is a silicon interface and must be connected.
To enable your pin, right-click the pin and choose Clear Attribute.
Required vs. Optional Bus Interfaces
A required bus interface means that it must be connected for the design to be considered legal. These are typically used
to designate the silicon interconnects that must be present between certain cores. For example, when using the Real
Time Counter in a Fusion design you must also connect it up to a Crystal Oscillator core.
An optional bus interface means that your design is still considered legal if it is left unconnected. However, it may not
functionally behave correctly.

Promoting Bus Interfaces to Top-level
To automatically connect a bus interface to a top-level port, select the bus interface, right-click, and choose Promote
To Top Level.
This automatically creates a top-level bus interface port of that name and connects the selected port to it. If a bus
interface port name already exists, a choice is given to either connect to the existing bus interface port or to create a new
bus interface port with a name <port name>_<i> where i = 1...n.
The signals that comprise the bus interface are also promoted.
Promoting a bus interface is a shortcut for creating a top-level port and connecting it to an instance pin.

Design State Management
When any component with instances in a SmartDesign design is changed, all instances of that component detect the
change.
If the change only affects the memory content, then your changes do not affect the component's behavior or port
interface and your SmartDesign design does not need to be updated.
If the change affects the behavior of the instantiated component, but the change does not affect the component's port
interface, then your design must be resynthesized, but the SmartDesign design does not need to be updated.
If the port interface of the instantiated component is changed, then you must reconcile the new definition for all
instances of the component and resolve any mismatches. If a port is deleted, SmartDesign will remove that port and
clear all the connections to that port when you reconcile all instances. If a new port is added to the component,
instances of that component will contain the new port when you reconcile all instances.
The affected instances are identified in your SmartDesign design in the Grid and the Canvas with an exclamation
point. Right-click the instance and choose Update With Latest Component.
Note: Note: For HDL modules that are instantiated into a SmartDesign design, if the modification causes syntax
errors, SmartDesign does not detect the port changes. The changes will be recognized when the syntax errors
are resolved.
Changing memory content
For certain cores such as Analog System Builder, Flash Memory, or FlexRAM it is possible to change the
configuration such that only the memory content used for programming is altered. In this case Project Manager (IDE)
will only invalidate your programming file, but your synthesis, compile, and place-and-route results will remain valid.
Libero IDE v9.1 User’s Guide
145
Incremental Design
When you modify the memory content of a core such as Analog System Builder or RAM with Initialization that is
used by a Flash Memory core, the Flash Memory core indicates that one of its dependent components has changed and
that it needs to be regenerated. This indication will be shown in the Hierarchy or Files Tab
.
In these cases, the Project Manager indicates that your programming file is out of date but your synthesis and placeand-route remain valid. You only need to regenerate your programming file in FlashPoint.
If any core is regenerated where the HDL file is not modified, the Project Manager design state will not invalidate your
Synthesis and/or Place-and-Route results. Some specific cores are listed below.
RAM with Initialization core - You can modify the memory content without invalidating synthesis.
Analog System Builder core - You can modify the following without invalidating synthesis:
•
Existing flag settings: threshold levels, assertion/de-assertion counts, OVER/UNDER type
•
Modifying sequence order or adding sequence operations
•
Changing acquisition times
•
Resistor Value for the Current Monitor
•
RTC time settings
•

•
Modifying memory file or memory content for clients
•

Unused Instance - You must remove this instance or connect at least one output pin to the rest of the design.
Out-of-date Instance - You must update the instance to reflect a change in the component referenced by this instance;
see Fixing an out-of-date instance.
Undriven Pin - To correct the error you must connect the pin to a driver or change the state, i.e. tie low (GND) or tie
high (VCC).
Floating Driver - You can mark the pin unused if it is not going to be used in the current design. Pins marked unused
are ignored by the Design Rules Check.
Unconnected Bus Interface - You must connect this bus interface to a compatible port because it is required
connection.
Required Bus Interface Connection – You must connect this bus interface before you can generate the design. These
are typically silicon connection rules.
Exceeded Allowable Instances for Core – Some IP cores can only be instantiated a certain number of times for legal
design. For example, there can only be one CortexM1 or CoreMP7 in a design because of silicon rules. You must
remove the extra instances.
Incompatible Family Configuration – The instance is not configured to work with this project’s Family setting. Either
it is not supported by this family or you need to re-instantiate the core.
Incompatible Die Configuration – The instance is not configured to work with this project’s Die setting. Either it is
not supported or you need to reconfigure the Die configuration.
Incompatible ‘Debug’ Configuration – You must ensure your CoreMP7 and CoreMP7Bridge have the same ‘Debug’
configuration. Reconfigure your instances so they are the same.
No RTL License, No Obfuscated License, No Evaluation License – You do not have the proper license to generate
this core. Contact Actel to obtain the necessary license.

Generating a SmartDesign Component
Before your SmartDesign component can be used by downstream processes, such as synthesis and simulation, you must
generate it.
To generate a SmartDesign component, from the SmartDesign menu, choose Generate or click
.
This will generate a HDL file in the directory <libero_project>/components/<library>/<yourdesign>.
Note: Note: The generated HDL file will be deleted when your SmartDesign design is modified and saved to ensure
synchronization between your SmartDesign component and its generated HDL file.
Generating a SmartDesign component may fail if there are any DRC errors. DRC errors must be corrected before you
generate your SmartDesign design.
Synthesizing the SmartDesign Component
Synthesizing a SmartDesign component using the Project Manager is the same as any other design component. See the
Synthesis help for more information on using the Project Manager to synthesize your design.
A SmartDesign component must be generated before it can be synthesized.
Note: Note: Once a component is set as root in the Project Manger Hierarchy, it can be synthesized.
Simulating the SmartDesign Component
Simulating a SmartDesign component is identical to simulating any other element in the Libero IDE Project Manager
Hierarchy (in the project using ModelSIM AE). See the ModelSIM AE with Libero IDE help and the ModelSIM
help for more information.
Simulating IPs
Some IPs are packaged with their own testbenches and verification suites. You can run these tests if you want to ensure
the IP is working properly.
To simulate an individual DirectCore IP:
1.

Naming Conventions
•
Project names must be less than 8 characters. For example: my_top
•
Do not use spaces, especially in:
Libero IDE v9.1 User’s Guide
•
Project names
•
Instance names
•
Net names
163
Reference
•
•
Port names
•
Schematic names
•
Stimulus file names
•
HDL names
Do not use any special characters in any of your naming, such as: ~ ! @ # $ % ^ & * ( ) = + { } | \ / < > ? ` ‘ “ “, . or
spaces.
•
The tool does not support the “inverted” net property.
•
If you want to rip out scalar bits from a bus, use [] for scalar bit naming. For example, Bus[15], Bus[14], …,
Bus[0]. If a bus DATA[15:0] is declared in the schematic then you can also use net names DATA5, DATA10
etc. to rip the DATA bus. If net DATA5 is unrelated to the DATA bus then you need to add a letter at the end
of the net name, e.g. DATA5N.
•
Do not use numbers at the beginning or the end of any names.
Scalar bit Bus1[15] of Bus1[15:0] can be confused with Scalar bit Bus11[5] of Bus11[15:0] during netlist
generation.
•
If you want to use numbers to distinguish related nets, use numbers followed by letters at the end, for example:
NET1N, or Bus1A[15:0].
•
Do not use naming “Bus[0:3][0:3]” to implement scalar bits. The second bus dimension is not supported. Instead
use: Bus[00], Bus[01]…, Bus[10], Bus[11]….
•
Multi-dimensional busses are not supported. For example, do not use naming "Bus[0:3][0:3]" in ViewDraw AE.
•
Do not name any component with the same name as Actel library components.
Finding an Inverted Signal in a Schematic
When looking for an inverted signal, use '~signal_name' instead of 'signal_name', since in schematic and wir files,
inverted signals are saved as '~signal_name'. Use the menu option Edit > Select to find the signal.
Using Connectors and I/O Pads
•
Use hierarchy connectors in any schematic design for any external ports and any ports of sub-modules.
•
You can insert I/O pads automatically by running Synthesis or Optimize & Insert Pads from Libero IDE. For
schematic designs, which only use Actel primitives (no HDL blocks), you can manually insert all I/O pads. This
is in case you do not want to go through the synthesis flow.

WaveFormer Pro generates VHDL and Verilog testbenches from drawn waveforms. Create your testbench after you
are done creating your design and wish to perform simulation. If you do not have WaveFormer Pro, create your
testbench with an alternative third-party tool.
There are five basic steps for creating testbenches using WaveFormer Pro and Libero IDE. These steps are described in
detail in the following sections.
To create a testbench using WaveFormer Pro:
1.
Click WaveFormer Pro in the Project Flow window. WaveFormer Pro starts and your signal information is
imported automatically.
2.
Using WaveFormer Pro, draw the waveforms to describe the testbench.
3.
From the Export menu, choose Export Timing Diagram and choose the save type as *.tim or *.btim. This saves
the waveforms.
4.
(Optional) Add VHDL Libraries and Use Clauses for VHDL export. These libraries or packages can be
included using the VHDL Libraries and Use Clauses dialog. From the Options menu, select the VHDL
Libraries and Use Clauses menu item to open this dialog.
5.
From the Export menu, choose Export Timing Diagram and choose the type of file to generate. To generate a
plain testbench model (which does not instantiate your model under test), choose one of the VHDL or Verilog
scripts. To simulate with the testbench model, you will need to write a top-level model that instantiates the
testbench model and the model under test. Below is a list of VHDL and Verilog testbench generation scripts:
5.
•
VHDL Wait (*.vhd)s
•
VHDL Transport (*.vhd)s
•
Verilog
From the File menu, choose Exit.
Note: Note: If you added extra signals to the testbench and do not want to export those signals, then double-click the
signal’s names to open the Signals Properties dialog and clear the Export check box.
Synplify always changes the data type to std_logic or std_logic_vector in the post_synthesis netlist. If your top-level
entity port is not std_logic or std_logic_vector and you need to run post-synthesis or post-layout simulation, you need
to change the data type in WFL.
To create two testbenches:
1.
172
Open the *.tim file and select the special data type signal, right-click and choose Edit Selected Signal.

ModelSimTM AE
2.
Choose std_logic or std_logic_vector under VHDL and click Save.
ModelSimTM AE
ModelSim Actel Edition (AE) is a custom edition of ModelSim PE that is integrated into Libero's design
environment. ModelSim for Actel is an OEM edition of Model Technology Incorporated’s (MTI) tools. ModelSim for
Actel supports VHDL or Verilog. It only works with Actel libraries and is supported by Actel.
Other editions of ModelSim are supported by Libero IDE. To use other editions of ModelSim with Libero IDE,
simply do not install ModelSim AE from the Libero CD.
Note: Note: ModelSim for Actel comes with its own online help and documentation. After starting ModelSim, click
the Help menu.

ModelSim Waveform window display settings.
•
Simulation Run Time - Specify how long the simulation should run in nanoseconds. If the value is 0, or if the
field is empty, there will not be a run command included in the run.do file.
•
Testbench module/entity name - Specify the name of your testbench entity name. Default is “testbench,” the
value used by WaveFormer Pro.
•
Top Level instance name in the testbench - Default is <top_0>, the value used by WaveFormer Pro. The Libero
IDE Project Manager replaces <top> with the actual top level macro when you run ModelSim.
•
Vsim Command Type - Select Minimum (Min), Typical (Typ), or Maximum (Max).
•
Resolution: The default is family-specific, but you can customize it to fit your needs.
Some custom simulation resolutions may not work with your simulation library. For example, simulation
resolutions above 1 ns will cause errors if you are using SX-A devices (the simulation errors out because of an
infinite zero-delay loop). Consult your simulation help for more information on how to work with your
simulation library and detect infinite zero-delay loops caused by high resolution values.

Save copies of your CoreConsole project stimulus files with new names if you wish to keep them.
You must import a CoreConsole BFM file into the Libero IDE in order to complete functional simulation (the BFM
is a stimulus file that you can edit to extend the testbench). VEC files are generated automatically from the BFM when
you run ModelSim.
The Project Manager overwrites your BFM file if you re-import your CoreConsole project. Edit and save your BFM
outside the Libero IDE project to prevent losing your changes. After you re-import your core-console project, you can
import your modified BFM again.

Performing Timing Simulation
Performing Timing Simulation
The steps for performing functional and timing simulation are nearly identical. Functional simulation is performed
before place-and-route and simulates only the functionality of the logic in the design. Timing simulation is performed
after the design has gone through place-and-route and uses timing information based on the delays in the placed and
routed designs.
Timing simulation includes much more detailed timing information for the targeted device. Timing simulation requires
a testbench.
To perform timing simulation:
1.
If you have not done so, back-annotate your design and create your testbench.
2.
Right-click the top level module in the Hierarchy and choose Organize Stimulus File from the right-click menu.
In the Organize Stimulus dialog box, all the stimulus files in the current Libero IDE project appear in the Stimulus Files in the
Project list box. Files already associated with the block appear in the Associated Files list box.

You can calculate junction temperature from values in the Actel Data Sheet, available at
http://www.actel.com/techdocs/ds/.
The temperature range represents the junction temperature of the device. For commercial and industrial devices, the
junction temperature is a function of ambient temperature, air flow, and power consumption.
For military devices, the junction temperature is a function of the case temperature, air flow, and power consumption.
Because Actel devices are CMOS, power consumption must be calculated for each design. For most low power
applications (e.g. 250mW), the default conditions are adequate.
Performance decreases approximately 2.5% for every 10 degrees C that the temperature values increase. Refer to the
SmartPower online help for more information about power consumption.

Radiation Derating
Conservative post-radiation performance estimates are available for some radiation tolerant devices based upon the
number of KRads the device is expected to be subjected to. Radiation effects vary by device lot and may not be
completely representative of the lot you are using. Post-radiation timing numbers are only meant to be a guide and are
not a guarantee of performance. Customers must consult the specific radiation performance report for the specific lot
used. Post radiation exposure estimates currently only affect timing numbers. The SmartPower power analysis tool is
not affected by changing the radiation exposure value.
RTSX-S and RTAX-S ONLY - Radiation Derating
This option is only available for RTSX-S and RTAX-S devices. The valid range is integer values from 0 to 300, and
the units are in KRads. Modifying this selection impacts the timing derating in SmartTime and back-annotating SDF
files, so when you modify this value, you must extract a new SDF file from Designer and re-evaluate the timing of your
design. It does not affect the device configuration.
Changing Design name and family
Design name and family are set when you create a new design. However, you can change this information for existing
designs. If you change the family, you must re-import the netlist. Use the following procedure to change the name of a
design and the targeted Actel family for the design.
To change the design name or family in Designer:

3.
Click OK. Refer to the Actel datasheet for your device for family specifications.
You may wish to migrate your SX device to an SX-A device. The SX to SX-A compatible family change option is
available in the Device Selection wizard.
To migrate your SX design to SX-A:
1.
Open your SX design.
2.
From the Designer Tools menu, choose Device Selection.
3.
Select SXA from the Change to drop-down menu, and proceed in the Device Selection Wizard to complete the
migration. You must re-compile and layout your design to run the Designer User Tools.
Changing device information
Device and package information, device variations, and operating conditions are set when you import a netlist and
compile a new design. However, you can change this information for existing designs.
To change device information for existing designs:
1.
In the Tools menu, choose Device Selection. The Device Selection Wizard appears.
2.
Select Die, Package, and Speed Grade and click Next. (You must select a die and package to continue.)
3.
Select Device Variations and click Next.
4.
Select Operating Conditions and click Finish.
Refer to the Actel FPGA Data Book or call your local Actel Sales Representative for information about device,
package, speed grade, variations, and operating conditions.
Compatible Die Change
When you change the device, some design information can be preserved depending on the type of change.
Changing Die Revisions
If you change the die from one technology to another, all information except timing is preserved. An example is
changing an A1020A (1.2µm) to an A1020B (1.0µm) while keeping the package the same.
Device Change Only
Constraint and pin information is preserved, when possible. An example is changing an A1240A in a PL84 package to
an A1280A in a PL84 package.
Repackager Function (Non-Axcelerator families only)
When the package is changed (for the same device), the Repackager automatically attempts to preserve the existing pin
and Layout information by mapping external pin names based on the physical bonding diagrams. This always works
when changing from a smaller package to a larger package (or one of the same size). When changing to a smaller
Libero IDE v9.1 User’s Guide

package, the Repackager determines if any of the currently assigned I/Os are mapped differently on the smaller
package. If any of the I/Os are mapped differently, then the layout is invalidated and the unassigned pins identified.
Importing Source Files
Source files include your netlist and constraint files.
Source files are files created by outside tools that will be tracked (audited) to better coordinate the design changes. If
you wish, you may import some files as auxiliary files. Auxiliary files are not audited, but you do not have to re-compile
your design after you import them.

Importing Source Files – Copying Files Locally
Designer in Libero IDE cannot import files from outside your project without copying them to your local project
folder. You may import source files from other locations, but they are always copied to your local folder. Designer in
Libero IDE always audits the local file after you import; it does not audit the original file.
When the Project Manager asks you if you want to copy files "locally", it means 'copy the files to your local project
folder'. If you do not wish to copy the files to your local project folder, you cannot import them. Your local project
folder contains files related to your Libero IDE project.
Files copied to your local folders are copied directly into their relevant directory: netlists are copied to the synthesis
folder; source files are copied to hdl folder and constraint files to constraint folder, etc. The files are also added to the
Libero IDE project; they appear in the Files tab.
Auditing Files
Designer audits your source files to ensure that your imported source files are current. All imported source files are date
and time stamped. Designer notifies you if the file is changed. When notified, select the appropriate action and click
OK.

Compiling your design
After you import your netlist files and select your device, you must compile your design. Compile contains a variety of
functions that perform legality checking and basic netlist optimization. Compile checks for netlist errors (bad

connections and fan-out problems), removes unused logic (gobbling), and combines functions to reduce logic count and
improve performance. Compile also verifies that the design fits into the selected device.
There are three ways to select the compile command:
•
In the Tools menu, select Compile.
•
Click the Compile button in the Design Flow.
•
Click the Compile icon in the toolbar.
If you have not already done so, Designer’s Device Selection Wizard prompts you to set the device and package.
During compile, the message window in the Main window displays information about your design, including warnings
and errors. Designer issues warnings when your design violates recommended Actel design rules. Actel recommends
that you address all warnings, if possible, by modifying your design before you continue.
If the design fails to compile due to errors in your input files (netlist, constraints, etc.), you must modify the design to
remove the errors. You must then re-import and re-compile the files.
After you compile the design, you can run Layout to place-and-route the design or use the User Tools (PinEditor,
ChipEditor, ChipPlanner, Timer, SmartPower, or NetlistViewer) to perform additional optimization prior to placeand-route.

Select this option to stop the flow if any error is reported in reading your PDC file. If you deselect this option, the tool
skips errors in reading your PDC file and just reports them as warnings. The default is ON.
Note: Note: The flow always stops even if this option is deselected in the following two cases:
•
If there is a Tcl error (For example, the command does not exist or the syntax of the command is incorrect)
•
The assign_local_clock command for assigning nets to LocalClocks fails. This may happen if any floor planning
DRC check fails, such as, region resource check, fix macro check (one of the load on the net is outside the local
clock region). If such an error occurs, then the Compile command fails. Correct your PDC file to proceed.
Note: Note: Every time you invoke this dialog box, this option is reset to its default value ON. This is to ensure that
you have a correct PDC file.
Display object names that are no longer found after netlist matching is performed on the design: Displays netlist

The interface provides a global control to the Compile component of the design flow.
Automatic Demotion/Promotion
Demote global nets whose fanout is less than: Enables the global clock demotion of global nets to regular nets.
By default, this option is OFF. The maximum fanout of a demoted net is 12.
Note: Note: A global net is not automatically demoted (assuming the option is selected) if the resulting fanout of the
demoted net is greater than the max fanout value. Actel recommends that the automatic global demotion only
act on small fanout nets. Actel recommends that you drive high fanout nets with a clock network in the design
to improve timing and routability.
Promote regular nets whose fanout is greater than: Enables global clock promotion of nets to global clock network. By
default, this option is OFF. The minimum fanout of a promoted net is 200.
But do not promote more than: Defines the maximum number of nets to be automatically promoted to global. The
default value is 0. This is not the total number as nets need to satisfy the minimum fanout constraint to be promoted.
The promote_globals_max_limit value does not include globals that may have come from either the netlist or PDC file
(quadrant clock assignment or global promotion).
Note: Note: Demotion of globals through PDC or Compile is done before automatic global promotion is done.
Libero IDE v9.1 User’s Guide
201
Device Selection
Note: You may exceed the number of globals present in the device if you have nets already assigned to globals or
quadrants from the netlist or by using a PDC file. The automatic global promotion adds globals on what
already exists in the design.
Local clocks
Limit the number of shared instances between any two non-overlapping local clock regions to: Defines the maximum
number of shared instances allowed to perform the legalization. It is also for quadrant clocks.
The maximum number of instances allowed to be shared by 2 local clock nets assigned to disjoint regions to perform
the legalization (default is 12, range is 0-1000). If the number of shared instances is set to 0, no legalization is
performed.
When inserting buffers to legalize shared instances between non-overlapping local clock regions, limit the buffers'
fanout to: Defines the maximum fanout value used during buffer insertion for clock legalization. Set the value to 0 to
disable this option and prevent legalization (default value is 12, range is 0-1000). If the value is set to 0, no buffer
insertion is performed. If the value is set to 1, there will be one buffer inserted per pin.
Note: Note: If you assign quadrant clock to nets using MultiView Navigator, no legalization is performed.

tree deletion is 12.
Note: Note: A net does not automatically remove its buffer tree (assuming the option is on) if the resulting fanout of
the net (if the buffer tree was removed) is greater than the max fanout value. Actel recomends that the

netlist file for that pin, and the PinEditor assignment is ignored. If you edit pin assignments in PinEditor, this option
is automatically set to Off.
Fanout messages
Use the control slider in the Messages area to control the warning level. Use the control slider to specify the fanout
limit that the Compile step checks against. Setting the control slider to '0' informs the system to use the system
defaults. Any non-zero value replaces the system default value for the fanout limit with the user-specified value.
Typically, this value range is 1 to 24.
This does not adjust the fanout of the design and it has no effect on the netlist. This only adjusts the warning level by
controlling what level of fanout checking you want to be warned about during Compile. Changing this fanout limit
option does not invalidate the Compile design state.

Design Constraints
Design constraints are usually either requirements or properties in your design. You use constraints to ensure that your
design meets its performance goals and pin assignment requirements.
The Designer software supports both timing and physical constraints. In addition, it supports netlist optimization
constraints. You can set constraints by either using Actel's interactive tools or by importing constraint files directly into
your design session.
Timing Constraints
Timing constraints represent the performance goals for your designs. Designer software uses timing constraints to
guide the timing-driven optimization tools in order to meet these goals.
You can set timing constraints either globally or to a specific set of paths in your design.
You can apply timing constraints to:
•
Specify the required minimum speed of a clock domain
•
Set the input and output port timing information
•
Define the maximum delay for a specific path
•
Identify paths that are considered false and excluded from the analysis
•
Identify paths that require more than one clock cycle to propagate the data
•
Provide the external load at a specific port
To get the most effective results from the Designer software, you need to set the timing constraints close to your design
goals. Sometimes slightly tightening the timing constraint helps the optimization process to meet the original
specifications.
Physical Constraints
Designer software enables you to specify the physical constraints to define the size, shape, utilization, and pin/pad
placement of a design. You can specify these constraints based on the utilization, aspect ratio, and dimensions of the
die. The pin/pad placement depends on the external physical environment of the design, such as the placement of the
device on the board.
There are three types of physical constraints:
•
I/O assignments
- Set location, attributes, and technologies for I/O ports
- Specify special assignments, such as VREF pins and I/O banks
•
Location and region assignments
Libero IDE v9.1 User’s Guide
213
Design Constraints
- Set the location of Core, RAM, and FIFO macros
- Create Regions for I/O and Core macros as well as modify those regions
•
Clock assignments
- Assign nets to clocks
- Assign global clock constraints to global, quadrant, and local clock resources
Netlist Optimization Constraints
The Designer software enables you to set some advanced design-specific netlist optimizing constraints.
You can apply netlist optimization constraints to:
•
Delete or restore a buffer tree
•
Manage the fan-outs of the nets
•
Manage macro combinations (for example, IO-REG combining)
•
Optimize a netlist by removing buffers and/or inverters, propagating constants, and so on

Entering Constraints
Entering Constraints
You can enter design constraints in the following ways:
•
Importing constraint files: You can import GCF, PDC, SDC, DCF, or PIN constraint files. The type of file
you use depends on which type of device you are designing.
- GCF (ProASIC and ProASICPLUS families)
- PDC (IGLOO, ProASIC3, SmartFusion, Fusion, and Axcelerator families)
- SDC (IGLOO, ProASIC3, SmartFusion, Fusion, Axcelerator, RTAX-S, eX, and SX-A families)
- DCF (earlier Antifuse families such as eX, SX-A, and SX)
- PIN (only valid for earlier Antifuse families such as eX, SX-A, and SX)
•
Using constraint editor tools: Designer's constraint editors are graphical user interface (GUI) tools for creating
and modifying physical, logical, and timing constraints. Using these tools enables you to enter constraints
without having to understand GCF, PDC, or other file syntax. Which constraint editor you use depends on
which type of device you are designing.
For IGLOO, ProASIC3, SmartFusion, Fusion, ProASICPLUS, ProASIC, and Axcelerator, use the tools within the
MultiView Navigator:
- ChipPlanner - Sets location and region assignments
- PinEditor in MVN - Sets the pin location constraints
- I/O Attribute Editor - Sets I/O attributes
- SmartTime Constraints EditorSmartTime Constraints Editor - Enables you to view and edit timing constraints
For all other families, you will use the following tools:
- ChipEditor - Sets location and region assignments
- PinEditor (non MVN)- Sets I/O attributes and pin location constraints
- Timer - Sets timing constraints

When running layout, use the Layout Options dialog box to set your layout options.
The I/O Bank Assigner and Global Planner run automatically after you click OK in the Layout Options dialog box.
The I/O Bank Assigner automatically assigns technologies to all I/O banks that have not been assigned a technology.
The Global Planner automatically assigns global nets to clock conditioning circuit (CCC) locations on the chip in the
design.
Note: Note: All I/O technologies assigned to I/O banks by the I/O Bank Assigner in Layout are unlocked.
Timing-Driven
Select this option to run Timing-Driven Layout. The primary goal of timing-driven layout is to meet timing
constraints, specified by you or generated automatically. Timing-driven Layout typically delivers better performance
than Standard layout.
If you do not select Timing-driven layout, Designer runs Standard layout. Standard layout targets efficient usage of the
chip resources. Chip performance is not optimized. Timing constraints are not considered by the Layout in standard
mode, although a delay report based on delay constraints entered in Timer can still be generated for the design. This is
helpful to determine if timing-driven Layout is required.
If your design has multiple scenarios, you can select a scenario from the pull-down list to perform timing driven layout.
Libero IDE v9.1 User’s Guide
229
Running Layout
Power-Driven
Select this option to run Power-Driven Layout. The primary goal of power-driven layout is to reduce dynamic power
while still maintaining timing constraints.
To get the most out of Power-Driven Layout, it is recommended to:
1.
Enter maximum delay, minimum delay, setup, and hold constraints in SmartTime's constraint editor or in SDC.
2.
Set false paths on any paths that have a constraint, but do not need one (this will help layout meet the
constraints that are needed).
3.
Perform Layout with Timing-Driven, Run Place, and Run Route options checked.
4.
Resolve worst case setup and maximum delay violations.
5.
Generate an SDF back-annotation file.
6.
Perform a post layout back-annotated simulation using this SDF file, and export a VCD (Value Change Dump)
file that will capture real activities for each net.
7.
Import this VCD file in Designer using the Import Auxiliary option from the File menu.
8.
Perform Layout with Timing-Driven and Power-Driven checked. Run Place and Route.
9.
Verify that your timing constraints are still met with SmartTime.
10.
Analyze your power with SmartPower.
In case you do not have simulation vectors for your design, the following alternative flow is recommended:
1.
Enter maximum delay, minimum delay, setup, and hold constraints in SmartTime's constraint editor or in SDC.
2.
Set false paths on any paths that have a constraint, but do not need one (this will help layout to meet the
constraints that are needed).
3.
Perform Layout with Timing-Driven, Run Place, and Run Route options checked.
4.
Resolve worst case setup and maximum delay violations.
5.
Verify that your timing constraints are still met with SmartTime.
6.
Open SmartPower and set clock frequencies and toggle rates for the different clocks. Clock frequencies can be
imported from your timing constraints. Refer to Initialize Frequencies for more information.
7.
Perform Layout with Timing-Driven, and Power-Driven options checked. Run Place and Route.
8.
Verify that your timing constraints are still met with SmartTime.
9.

Run Place
Select this option to run the placer during Layout. By default, it reflects the current Layout state. If you have not run
Layout before, Run Place is selected by default. If your design has already been placed but not routed, this box is
cleared by default. You can also select the following incremental placement options.
•
230
Incrementally: Select to use previous placement data as the initial placement for the next place run.
Libero IDE v9.1 User’s Guide
IGLOO, ProASIC3, SmartFusion and Fusion Advanced Layout Options
•
Lock Existing Placement (fix): Select to preserve previous placement data during the next incremental placement
run.
Incremental options apply to the entire design. For more detailed control of the placer behavior (such as, to fix
placement of a portion of the design), use the MultiView Navigator tools or set fixed attributes on the placed instances
via PDC constraint files.
Run Route
Select to run the router during Layout. By default, it reflects the current Layout state. If you have not run Layout
before, Run Route is checked. Run Route is also checked if your previous Layout run completed with routing failures.
If your design has been routed successfully, this check box is cleared.
•
Incrementally: Select to fully route a design when some nets failed to route during a previous run. You can also
use it when the incoming netlist has undergone an ECO. (Engineering Change Order). Incremental routing
should only be used if a low number of nets fail to route (less than 50 open nets or shorted segments). A high
number of failures usually indicates a less than optimal placement (if using manual placement through macros,
for example) or a design that is highly connected and does not fit in the device. If a high number of nets fail,
relax constraints, remove tight placement constraints, deactivate timing-driven mode, or select a bigger device
and rerun Layout. Also, see the Advanced Layout options for your device.
There is no "Fix" option for the router. In incremental mode the router tries to preserve the existing routing; there is no
guarantee that it will be preserved. Therefore the timing characteristics of the previously routed portion of the design
may change, even if the placement was fixed for that portion of the design. The chance of this is quite small, and the
router will print the list of nets that have fixed terminals (i.e. those nets whose every pin's macro has the placement FIX
attribute).
Use Multiple Passes
Select to run layout multiple times with different seeds. Multiple Pass Layout attempts to improve layout quality by
selecting from a greater number of layout results. Click Configure to set your Multiple Pass Configuration.
Click the Advanced button to set Timing-Driven options.

231
Running Layout
High Effort Layout Mode
This option turns on netlist optimizations to obtain better performance. Layout runtime will increase when this option
is selected. You can also combine this option with the Multi-Pass mode to achieve the best possible performance.
In the regular flow the compile step in Designer would modify the netlist to make use of efficient resources on the chip,
such as global networks and special macros. When the High Effort Layout option is turned on, the placer could further
change the mapping of the logic components, preserving the original functionality of the design. The changed netlist is
then used in all post-layout Designer tools including back-annotation.
The names and types of the combinational core logic primitives may change. All other logic cells (such as registers,
memory, I/Os or clocks) or combinational logic primitives that are assigned a physical constraint (locked at a location,
assigned to a region, or part of a block component), referred in a timing constraint, or have a preserve property, will
remain unchanged.
When the Lock Existing Placement option is also turned on, the placer runs in regular effort mode.
Note: Note: If you change the High Effort Setting you must re-run the placer and router to complete Layout.
Sequential Optimization
This option turns on optimization of sequential cells in the High Effort Layout mode. This typically enables register
retiming without disturbing timing latency. The names of registers may change unless they are assigned a physical
constraint (locked at a location, assigned to a region, or part of a block component), referred in a timing constraint, or
have a preserve property. Other restrictions may also apply.
Router
Repair Minimum Delay Violations
With this option selected, layout will perform an additional route that will attempt to repair paths that have minimum
delay and hold time violations. This is done by increasing the length of routing paths and inserting routing buffers to
add delay to paths. Since placement will remain unchanged and no additional tiles or modules will be inserted, the
amount of delay inserted is limited. As a result, this function is best suited to repair paths with small (0 to 3 ns) hold
and minimum delay violations. Paths with large violations will likely improve, but for a complete repair of these paths,
manual placement or source code modification may be necessary. Every effort will be made to avoid creating max-delay
timing violations on worst case paths.
To get the most out of repair minimum delay violations, it is recommended to:
1.
Enter max-delay, min-delay, setup and hold constraints in SmartTime's constraint editor or in SDC.
2.
Set false paths on any paths that have a constraint, but do not need one (this will help layout to meet the
constraints that are needed).
232
3.
Perform Layout with Timing Driven, Run Place, Run Route and optionally Run incrementally enabled.
4.
Resolve worst case setup and max-delay violations before running minimum delay violations repair.
Libero IDE v9.1 User’s Guide
ProASICPLUS and ProASIC Layout Options
5.
After worst case max-delay timing is resolved, evaluate timing in SmartTime’s Timing Analyzer in minimum
delay analysis mode to check for hold time and minimum delay violations.
6.
Run repair minimum delay violations with incremental route enabled.
The repair minimum delay violations tool will attempt to fix all hold time and minimum delay violations by
lengthening routing delay paths and inserting routing buffers. As delay is added to paths, worst case max-delay
timing is verified to avoid creating new max-delay timing violations. Designer will report the worst minimum
slack and the number of violating paths in the log window. In some cases, additional improvement can occur by
running repair minimum delay violations multiple times with Run Incrementally enabled.
7.
Perform both maximum and minimum delay timing analysis to check the timing. Manual placement or source
code modification may be necessary to repair all minimum delay violations.
8.
After making placement or source code changes, run incremental route and repair minimum delay violations, and
then analyze timing again.
Additional Factors
Runtime may vary greatly with the number of paths that need repair, the number of nets in those paths, and the
resources available for the tool to insert delay. Over-constraining paths will increase runtime, but will not likely improve
results .
The tool will only work on paths that have min delay and hold time constraints. However, other paths that share
common nets to the constrained paths may be inadvertently affected.
It is recommended to run minimum delay violations repair with incremental route. This will ensure that paths which
do not have minimum delay violations are preserved.
Repair will be performed on:
•
Register to register paths where both registers are on the same global or non-global clock
•
Register to register paths where the registers are on different clock networks and a minimum delay constraint
exists
•
Input to register, register to output, clock to out, input to output paths with minimum delay or hold constraint.
You may select programmable input delays to increase delay on input to register paths for devices that support the
feature.

There is no "Fix" option for the router. In incremental mode the router tries to preserve the existing routing; there is no
guarantee that it will be preserved. Therefore the timing characteristics of the previously routed portion of the design
may change, even if the placement was fixed for that portion of the design.

Layout Timing Weight
Setting this option to values within a recommended range of 1-4 changes the weight of the timing objective function,
thus influencing the results of timing-driven place-and-route in favor of either routability or performance.
Value 4 (default) puts maximum emphasis on the performance; value 1 shifts priority to routability, but still evaluates
timing goals during layout.
In general, the performance of a non-congested design increases with a higher timing weight setting. In highly
congested designs the performance improves with lower timing weight settings because of better routability. Use
intermediate values to balance the performance-routability tradeoff for your design.
For designs that are very congested, you may want to put even more emphasis to the routability than level 1 provides.
In this case try running standard-mode placer, followed by the timing-driven router. If this is insufficient, run both
place-and-route in standard mode.
Note: Note: If you change the Timing Weight you must re-run the placer to complete routing. Changing the Timing
Weight has no effect if you do not re-run the placer.

Power-Driven
Select this option to run Power-Driven Layout. The primary goal of power-driven layout is to reduce dynamic power
while still maintaining timing constraints.
To get the most out of Power-Driven Layout, it is recommended to:
1.
Enter maximum delay, minimum delay, setup, and hold constraints in SmartTime's constraint editor or in SDC.
2.
Set false paths on any paths that have a constraint, but do not need one (this will help layout meet the
constraints that are needed).

Run Place
Select this option to run the placer during Layout. If you have not run Layout before, Run Place is selected by default.
If your design has already been placed but not routed, this check box is not selected. You can also select the following
incremental placement options.
•
Incrementally: Select to use previous placement data as the initial placement for the next placement run.
•

Use the Effort Level slider to increase the placement effort. The range is 1 to 5 with a default of 3. A higher level of
effort generally improves the quality of results, but runs longer.
Run Route
Select to run the router during Layout. If you have not run Layout before, Run Route is selected. Run Route is also
selected if your previous Layout run completed with routing failures.
Incremental routing is available for Axcelerator devices. When activated, the option sets the previous routing

Router
Repair Minimum Delay Violations
With this option selected, layout will perform an additional route that will attempt to repair paths that have minimum
delay and hold time violations. This is done by increasing the length of routing paths and inserting routing buffers to
add delay to paths. Since placement will remain unchanged and no additional tiles or modules will be inserted, the
amount of delay inserted is limited. As a result, this function is best suited to repair paths with small (0 to 3 ns) hold
and minimum delay violations. Paths with large violations will likely improve, but for a complete repair of these paths,
manual placement or source code modification may be necessary. Every effort will be made to avoid creating max-delay
timing violations on worst case paths.
To get the most out of repair minimum delay violations, it is recommended to:
1.
Enter max-delay, min-delay, setup and hold constraints in SmartTime's constraint editor or in SDC.

6.
Run repair minimum delay violations with incremental route enabled.
The repair minimum delay violations tool will attempt to fix all hold time and minimum delay violations by
lengthening routing delay paths and inserting routing buffers. As delay is added to paths, worst case max-delay
timing is verified to avoid creating new max-delay timing violations. Designer will report the worst minimum
slack and the number of violating paths in the log window. In some cases, additional improvement can occur by
running repair minimum delay violations multiple times with Run Incrementally enabled.

then analyze timing again.
Note: Note: Runtime may vary greatly with the number of paths that need repair, the number of nets in those paths,
and the resources available for the tool to insert delay. Over-constraining paths will increase runtime, but will
not likely improve results.
The tool will only work on paths that have min delay and hold time constraints. However, other paths that share
common nets to the constrained paths may be inadvertently affected.

Running Layout
Actel recommends that you run minimum delay violations repair with incremental route. This will ensure that paths
which do not have minimum delay violations are preserved.
Repair will be performed on:
•
Register to register paths where both registers are on the same global or non-global clock
•
Register to register paths where the registers are on different clock networks and a minimum delay constraint
exists
•
Input to register, register to output, clock to out, input to output paths with minimum delay or hold constraint.
You may select programmable input delays to increase delay on input to register paths for devices that support the
feature.

When not checked, standard layout runs. Standard layout maximizes the average performance for all paths. Each part
of a design is treated equally for performance optimization. Standard layout uses net weighting (or criticality) to

Extended Run
Select this to run a greater number of iterations during optimization within a single layout pass. An extended run layout
can take up to five times as long as a normal layout.
Effort Level
This setting specifies the duration of the timing-driven phase of optimization during timing-driven Layout. Its value
specifies the duration of this phase as a percentage of the default duration. This option is available only when timing
constraints have been defined
The default value is 100 and the selectable range is 25 - 500. Reducing the effort level also reduces the run time of
timing-driven place-and-route (TDPR). With an effort level of 25, TDPR is almost four times faster. With fewer
iterations, however, performance may suffer. Routability may or may not be affected. With an effort level of 200,
TDPR is almost two times slower. This variable does not have much effect on timing.
Timing Weight
Setting this option to values within a recommended range of 10-150 changes the weight of the timing objective
function, thus influencing the results of timing-driven place-and-route in favor of either routability or performance.
This option is available only when timing constraints have been defined
The timing weight value specifies this weight as a percentage of the default weight (i.e. a value of 100 has no effect). If
you use a value less than 100, more emphasis is placed on routability and less on performance. Such a setting would be
appropriate for a design that fails to route with TDPR. In case more emphasis on performance is desired, set this
variable to a value higher than 100. In this case, routing failure is more likely. A very high timing value weight could
also distort the optimization process and degrade performance. A value greater than 150 is not recommended.

Incremental Placement
In either standard or timing-driven mode, use incremental placement to preserve the timing of a design after a
successful place-and-route, even if you change part of the netlist. Incremental placement has no effect the first time you
run layout. During design iteration, incremental placement attempts to preserve the placement information for any
unchanged macros in a modified netlist.
As a result, the timing relationships for unchanged macros approximate their initial values, decreasing the execution
time to perform Layout. By forcing Designer to retain the placement information for a portion of the design, some
flexibility for optimal design layout may be lost. Therefore, do not use incremental placement to place your design in
pieces. You should only use it if you have successfully run Layout and you have minor changes to your design.
Incremental placement requires prior completion of place. Do not use incremental placement if the previous Layout
failed to meet performance goals.
240
Libero IDE v9.1 User’s Guide
Running Multiple Pass Layout
Locking Existing Placement (Fix)
When the Lock Existing Placement option is selected in the Layout dialog box, all unchanged macros are treated as
locked (fixed) placements during an incremental placement. This is the strongest level of control, but it may be too
restrictive for the new placement to successfully complete. The default ON setting treats unchanged macro locations as
placement hints, but alters their locations as needed to successfully complete placement. Refer to ChipEditorfor details
on locking macros.
ProASIC and ProASICPLUS Placement Constraint File (GCF)
For ProASIC and ProASICPLUS designs, you can export a GCF constraint file to get all of the constraint information.
From the File menu, choose Export > Constraint Files, type a file name and click Save, and then select All GCF
constraints in the Export GCF File dialog box. Blocks with locked placement constraints generate locked placement
constraints, while the others generate initial placement constraints. You can edit a GCF file to remove existing
constraints or add new constraints. You must then import the modified GCF file as well as the netlist back into
Designer. See Importing Source Files for more information about importing files.
Running Multiple Pass Layout
Multiple Pass Layout attempts to improve layout quality by selecting from a greater number of Layout results. This is
done by running individual place and route multiple times with varying placement seeds and measuring the best results
with specified criteria.
Note: Note:
•
Before running Multiple Pass Layout, you need to save your design.
•
Multiple Pass Layout is supported in the following families: IGLOO, Fusion, ProASIC3, Axcelerator,
ProASICPLUS, ProASIC, SX-A, and eX.
•
Multiple Pass Layout saves your design file with the pass that has the best layout results. If you want to preserve
your existing design state, you should save your design file with a different name before proceeding. To do this,
from the File menu, select Save As.
•
Four types of reports (timing, maximum delay timing violations, minimum delay timing violations, and power)
for each pass will be written out to the working directory to assist you in later analysis:
•
<adbFileName>_timing_r<runNum>_s<seedIndex>.rpt
•
<adbFileName>_timing_violations_r<runNum>_s<seedIndex>.rpt

Maximum delay: Select to examine timing violations (slacks) obtained from maximum delay analysis.
•
Minimum delay: Select to examine timing violations (slacks) obtained from minimum delay analysis.
•
Select by: Worst Slack or Total Negative Slack to specify the slack criteria.
•
When Worst Slack is selected, the most amount of negative slack (or least amount of
positive slack if all constraints are met) for each pass is identified, and then the largest
value out of all passes determines the best pass.
•
When Total Negative Slack is selected, the sum of negative slacks from the first 100
paths for each pass is identified, and then the largest value out of all the passes
determines the best pass. If no negative slacks exist for a pass, then the worst slack is
used to evaluate that pass.
•
Stop on first path without violations: Select to stop performing remaining passes if all timing constraints have
been met (when there are no negative slacks reported in the timing violations report).
•
Total power: Select to determine the best pass to be the one that has the lowest total power (static + dynamic)
out of all layout passes.
Save design file for each pass: Select to save the design *.adb file for each pass. By default, only the best result is saved
to your design. With this option, every pass stores its design file as <adbFileName>_r<runNum>_s<seedIndex>.adb. The
"best"-pass design will also be written back to the original *.adb file. Saving all results does take more disk space, but
allows you to analyze the result of each pass later in more detail. <adbFileName>_iteration_summary.rpt provides
additional details about the saved files.

Flip-flop reports
The flip-flop report enables you to create a report that lists the number and type of flip-flops used in a design.
In ProASIC3: CC macros in the report are multi-tile flip-flops, which are flip-flops, made of 2 or 4 tiles
All other families: CC macros are flip-flops made of 2 combinatorial macros.
You can generate two types of reports - Summary or Extended:
A Summary report displays whether the flip-flop is a sequential, or multi-tile flip-flop, the macro implementation of
the flip-flop, and the number of times the implementation of the flip-flop is used in the design.
An Extended report lists the names of the macros in the design individually.
To generate a flip-flop report:

I/O Functionality
This section of the report indicates the total number of regular input, output, and bidirectional signals. This also shows
the differential input and output in the design. The I/O categories are: regular I/Os, registered I/Os or DDR I/Os in
the current design.
I/O Technologies
This section of the report specifies the VCCI and VREF voltage requirements for each I/O standard and the number
of user I/Os per I/O standards used in the current design.
Note: Note: For voltage referenced I/O standards, input and bidirectional I/Os require both a VCCI and a VREF
power supply whereas output I/Os only require a VCCI power supply. This is why these two categories are
shown separately in this section.
I/O Banks
This section of the report specifies the following I/O bank characteristics:
•

•
Total number of single-ended I/Os available and used for each bank.
•

assigned a VREF voltage.
•
Total number of voltage referenced I/Os available and used for each bank. Voltage referenced I/Os are available
only if VREF pins have been assigned.
I/O Voltages
This section of the report indicates the current design voltage requirements.
For each VCCI and VCCI/VREF user I/O demand in the current design, this table reports the total number of
bonded I/Os available on the device that satisfy this demand.
Note: Note: For an I/O bank assignment (VCCI and VREF assignment) to be valid for the current design, the I/O
voltage table must show no violation. Violations are indicated with an asterisk ("*") when the number of user
I/Os that need a given VCCI or VCCI/VREF assignment is less than the total number of bonded I/Os that
can satisfy this demand.

Cycle-Accurate Power Reports
Traditional power analysis based on a VCD simulation file reports an average power for the entire simulation time.
Based on a VCD simulation file, the cycle-accurate power analysis will report one power value per clock period (or halfperiod) instead of an average power for the whole simulation. This feature allows to easily identify the worst cycle in
terms of power performance; and helps to understand and further minimize power consumption by facilitating the
analysis of data-dependent power variations, as well as dynamic power variations due to clock-gating, or even clock
frequency variations.

Global Usage report
The Global Usage report provides information about the net(s) that are assigned or routed using Global or LocalClock
resources.
You can generate this report in either pre or post route state of the design.
In pre-routed state, the Global Usage report displays the following information:
•
Net(s) assigned to Global resources
•
Net(s) assigned to LocalClock resources
In post-routed state, the Global Usage report displays the following information:
•
Net(s) that are routed using Global resources
•
Net(s) that are routed using LocalClock resources
•
Net(s) that are constrained to use LocalClock resources but routed using Regular resources. In this case, the tool
displays a warning message at the end of the report.
To create a Global Usage report:
From the Tools menu, choose Reports > Global > GlobalUsage.

Some testers may have memory size restrictions for a single SVF file. The SVF limit file option enables you to limit the size of
each SVF file by either file size or vectors.
The generated SVF files append an index to the file name indicating the sequence of files. The format is:
<SVF_filename>_XXXXX.svf
where XXXXX is the index of the SVF file. The first SVF file begins with <SVF_filename>_00000.svf and increments by 1 until
file generation is complete.
Maximum file size: Max file size limit for the SVF file; use this option to limit your SVF file size based on number of kB.
Maximum number of vectors: Max vector limit for the SVF file; use this option to limit the size of your SVF based on number of

Custom Serialization Data for FlashROM Region
Custom Serialization Data for FlashROM Region
FlashPoint enables you to specify a custom serialization file as a source to provide content for programming into a Read
from file FlashROM region. You can use this feature for serializing the target device with a custom serialization
scheme.
To specify a FlashROM region:
1.
From the Properties section in the FlashROM Settings page, select the file name of the custom serialization file
(see figure below). For more information on custom serialization files, see Custom Serialization Data File
Format.
Figure 109 · FlashROM Settings
2.
Select the FlashROM programming file type you want to generate from the two options below:
•
Single programming file for all devices option: generates one programming file with all the values in the custom
serialization file.
•
One programming file per device: generates one programming file for each value in the custom serialization file.
3.
Enter the number of devices you want to program.
4.
Click the Target Programmer button.
5.
Select your target Programmer type.
6.
Click OK.
Custom Serialization Data File Format
FlashPoint supports custom serialization data files that specify the data in binary, HEX, decimal, or ASCII text. The
custom serialization data files may contain multiple data with the Line Feed (LF) character as the delimiter. You can
create a file by entering serialization data into any type of text editor. Depending on the serialization data format (hex,
Libero IDE v9.1 User’s Guide
311
Generating Programming Files
ASCII, binary, decimal), input the serialization data according to the size of the region you specified in the FlashROM
settings page.
Semantics
Each custom serialization file has only one type of data format (binary, decimal, Hex or ASCII text). For example, if a
file contains two different data formats (i.e. binary and decimal) it is considered an invalid file.
The length of each data file must be shorter or equal to the selected region length. If the data is shorter then the
selected region length, the most significant bits shall be padded with 0’s. If the specified region length is longer then
the selected region length, it is considered an invalid file.
The digit / character length is as follows:
-Binary digit: 1 bit
-Decimal digit: 4 bits
-Hex digit: 4 bits
-ASCII Character: 8 bits
Note: Note the standard example below:
If you wanted to use, for example, device serialization for three devices with serialization data 123, 321, and 456, you
would create file name from_read.txt. Each line in from_read.txt corresponds to the serialization data that will be
programmed on each device. For example, the first line corresponds to the first device to be programmed, the second
line corresponds to the second device to be programmed, and so on.
Hex serialization data file example
The following example is a Hex serialization data file for a 40-bit region. Enter the serialization data below into file
created by any text editor:
123AEd210
AeB1
0001242E
Note: Note: If you enter an invalid Hex digit such as 235SedF1, an error occurs. An error will also occur if you enter
data that is out of range, i.e. 4300124EFE.
The following is an example of programming "AeB1" into Region_7_1 located on page 7, from Word 5 to Word 1 in
the FlashROM settings page. See Custom serialization data for FlashROM region for more information.

FlashLock®
Figure 112 · I/O States During Programming Dialog Box
FlashLock®
Actel’s ProASIC and ProASICPLUS devices contain FlashLock circuitry to lock the device by disabling the
programming and readback capabilities after programming. Care has been taken to make the locking circuitry very
difficult to defeat through electronic or direct physical attack.
FlashLock has three security options: No Lock, Permanent Lock, and Keyed Lock.
No Lock
Creates a programming file which does not secure your device.
Permanent Lock
The permanent lock makes your device one time programmable. It cannot be unlocked by you or anyone else.
Keyed Lock
Within each ProASIC and ProASICPLUS device, there is a multi-bit security key user key. The number of bits depends
on the size of the device. The tables below show the key size of different ProASIC and ProASICPLUS devices,
respectively. Once secured, read permission and write permission can only be enabled by providing the correct user key
to first unlock the device. The maximum security key for the device is shown in the dialog box.

Basic syntax
Introduction to Tcl Scripting
Tcl, the Tool Command Language, pronounced tickle, is an easy-to-learn scripting language that is compatible with
Libero IDE and Designer software. You can run scripts from either the Windows or UNIX command line or store and
run a series of commands in a *.tcl batch file.
This section provides a quick overview of the main features of Tcl:
•
Basic syntax
•
Types of Tcl commands
•
Variables
•
Command substitution
•
Quotes and braces
•
Lists and arrays
•
Control structures
•
Handling exceptions
•
Print statement and Return values

•
Project Manager Tcl Commands
•
Designer Tcl Commands
For complete information on Tcl scripting, refer to one of the books available on this subject. You can also find
information about Tcl at web sites such as http://www.tcl.tk.
Basic syntax
Tcl scripts contain one or more commands separated by either new lines or semicolons. A Tcl command consists of the
name of the command followed by one or more arguments. The format of a Tcl command is:
command arg1 ... argN
The command in the following example computes the sum of 2 plus 2 and returns the result, 4.
expr 2 + 2
The expr command handles its arguments as an arithmetic expression, computing and returning the result as a string.
All Tcl commands return results. If a command has no result to return, it returns an empty string.
Libero IDE v9.1 User’s Guide
325
TCL Command Reference
To continue a command on another line, enter a backslash (\) character at the end of the line. For example, the
following Tcl command appears on two lines:
import -format "edif" -netlist_naming "Generic" -edif_flavor "GENERIC" {prepi.edn}
Comments must be preceded by a hash character (#). The comment delimiter (#) must be the first character on a line
or the first character following a semicolon, which also indicates the start of a new line. To create a multi-line
comment, you must put a hash character (#) at the beginning of each line.
Note: Note: Be sure that the previous line does not end with a continuation character (\). Otherwise, the comment
line following it will be ignored.
Special characters
Square brackets ([ ]) are special characters in Tcl. To use square brackets in names such as port names, you must either
enclose the entire port name in curly braces, for example, pin_assign -port {LFSR_OUT[15]} -iostd lvttl -slew High,
or lead the square brackets with a slash (\) character as shown in the following example:
pin_assign -port LFSR_OUT\[15\] -iostd lvttl -slew High

Types of Tcl commands
There are three types of Tcl commands:
•
Built-in commands
•
Procedures created with the proc command
•
Commands built into the Designer software
Built-in commands
Built-in commands are provided by the Tcl interpreter. They are available in all Tcl applications. Here are some
examples of built-in Tcl commands:
•
Tcl provides several commands for manipulating file names, reading and writing file attributes, copying files,
deleting files, creating directories, and so on.
•
exec - run an external program. Its return value is the output (on stdout) from the program, for example:
set tmp [ exec myprog ]
puts stdout $tmp
•
You can easily create collections of values (lists) and manipulate them in a variety of ways.
•
You can create arrays - structured values consisting of name-value pairs with arbitrary string values for the names
and values.
•
You can manipulate the time and date variables.
•
You can write scripts that can wait for certain events to occur, such as an elapsed time or the availability of input
data on a network socket.
Procedures created with the proc command
You use the proc command to declare a procedure. You can then use the name of the procedure as a Tcl command.
The following sample script consists of a single command named proc. The proc command takes three arguments:
•
The name of a procedure (myproc)
•
A list of argument names (arg1 arg2)
•
The body of the procedure, which is a Tcl script
proc myproc { arg1 arg2 } {
# procedure body
}
myproc a b

Many functions that you can perform through the Designer software's GUI interface, you can also perform using an
equivalent Tcl command. For example, the backannotate command is equivalent to executing the Back-Annotate
command from Designer's Tools menu. For a list of Tcl commands supported in the Designer software, see "Tcl
Commands."
Variables
With Tcl scripting, you can store a value in a variable for later use. You use the set command to assign variables.For
example, the following set command creates a variable named x and sets its initial value to 10.
set x 10
A variable can be a letter, a digit, an underscore, or any combination of letters, digits, and underscore characters. All
variable values are stored as strings.
In the Tcl language, you do not declare variables or their types. Any variable can hold any value. Use the dollar sign ($)
to obtain the value of a variable, for example:
set a 1
set b $a
set cmd expr
set x 11
$cmd $x*$x
The dollar sign $ tells Tcl to handle the letters and digits following it as a variable name and to substitute the variable
name with its value.
Global Variables
Variables can be declared global in scope using the Tcl global command. All procedures, including the declaration can
access and modify global variables, for example:
global myvar
Command substitution
By using square brackets ([]), you can substitute the result of one command as an argument to a subsequent command,
as shown in the following example:
set a 12
set b [expr $a*4]
Tcl handles everything between square brackets as a nested Tcl command. Tcl evaluates the nested command and
substitutes its result in place of the bracketed text. In the example above, the argument that appears in square brackets
in the second set command is equal to 48 (that is, 12* 4 = 48).
Conceptually,
set b [expr $a * 4]
expands to
328
Libero IDE v9.1 User’s Guide
Quotes and braces
set b [expr 12 * 4 ]
and then to
set b 48
Quotes and braces
The distinction between braces ({ }) and quotes (" ") is significant when the list contains references to variables. When
references are enclosed in quotes, they are substituted with values. However, when references are enclosed in braces,
they are not substituted with values.
Example
With Braces
With Double Quotes
set b 2
set b 2
set t { 1 $b 3 }
set t " 1 $b 3 "
set s { [ expr $b + $b ] }
set s " [ expr $b + $b ] "
puts stdout $t
puts stdout $t
puts stdout $s
puts stdout $s
will output
1 $b 3
[ expr $b + $b ]
vs.
1 2 3

Filenames
In Tcl syntax, filenames should be enclosed in braces { } to avoid backslash substitution and white space separation.
Backslashes are used to separate folder names in Windows-based filenames. The problem is that sequences of “\n” or
“\t” are interpreted specially. Using the braces disables this special interpretation and specifies that the Tcl interpreter
handle the enclosed string literally. Alternatively, double-backslash “\\n” and “\\t” would work as well as forward slash
directory separators “/n” and “/t”.For example, to specify a file on your Windows PC at c:\newfiles\thisfile.adb, use one
of the following:
{C:\newfiles\thisfile.adb}
C:\\newfiles\\thisfile.adb
"C:\\newfiles\\thisfile.adb"
C:/newfiles/thisfile.adb
"C:/newfiles/thisfile.adb"
If there is white space in the filename path, you must use either the braces or double-quotes. For example:
C:\program data\thisfile.adb
should be referenced in Tcl script as
Libero IDE v9.1 User’s Guide
329
TCL Command Reference
{C:\program data\thisfile.adb} or "C:\\program data\\thisfile.adb"
If you are using variables, you cannot use braces { } because, by default, the braces turn off all special interpretation,
including the dollar sign character. Instead, use either double-backslashes or forward slashes with double quotes. For
example:
"$design_name.adb"
Note: Note: To use a name with special characters such as square brackets [ ], you must put the entire name between
curly braces { } or put a slash character \ immediately before each square bracket.
The following example shows a port name enclosed with curly braces:
pin_assign -port {LFSR_OUT[15]} -iostd lvttl -slew High
The next example shows each square bracket preceded by a slash:
pin_assign -port LFSR_OUT\[15\] -iostd lvttl -slew High
Lists and arrays
A list is a way to group data and handle the group as a single entity. To define a list, use curly braces { } and double
quotes “ “. For example, the following set command {1 2 3 }, when followed by the list command, creates a list stored in
the variable "a." This list will contain the items "1," "2," and "3."
set a { 1 2 3 }
Here's another example:
set e 2
set f 3
set a [ list b c d [ expr $e + $f ] ]
puts $a
displays (or outputs):
b c d 5
Tcl supports many other list-related commands such as lindex, linsert, llength, lrange, and lappend. For more
information, refer to one of the books or web sites available on this subject.
Arrays
An array is another way to group data. Arrays are collections of items stored in variables. Each item has a unique
address that you use to access it. You do not need to declare them nor specify their size.
Array elements are handled in the same way as other Tcl variables. You create them with the set command, and you
can use the dollar sign ($) for their values.
set myarray(0) "Zero"
set myarray(1) "One"
set myarray(2) "Two"
for {set i 0} {$i < 3} {incr i 1} {
Output:
Zero
One
330
Libero IDE v9.1 User’s Guide
Control structures
Two
In the example above, an array called "myarray" is created by the set statement that assigns a value to its first element.
The for-loop statement prints out the value stored in each element of the array.
Special arguments (command-line parameters)
You can determine the name of the Tcl script file while executing the Tcl script by referring to the $argv0 variable.
puts “Executing file $argv0”
To access other arguments from the command line, you can use the lindex command and the argv variable:
To read the the Tcl file name:
lindex $argv 0
To read the first passed argument:
lindex $argv 1
Example
puts "Script name is $argv0" ; # accessing the scriptname
puts "first argument is [lindex $argv 0]"
puts "second argument is [lindex $argv 1]"
puts "third argument is [lindex $argv 2]"
puts "number of argument is [llength $argv]"
set des_name [lindex $argv 0]
puts "Design name is $des_name"
Control structures
Tcl control structures are commands that change the flow of execution through a script. These control structures
include commands for conditional execution (if-then-elseif-else) and looping (while, for, catch).
An "if" statement only executes the body of the statement (enclosed between curly braces) if the Boolean condition is
found to be true.
if/else statements
if { “$name” == “paul” } then {
…
# body if name is paul
} elseif { $code == 0 } then {
…
# body if name is not paul and if value of variable code is zero
} else {
…
# body if above conditions is not true
}
for loop statement
A "for" statement will repeatedly execute the body of the code as long as the index is within a specified limit.
Libero IDE v9.1 User’s Guide
331
TCL Command Reference
for { set i 0 } { $i < 5 } { incr i } {
…
# body here
}
while loop statement
A "while" statement will repeatedly execute the body of the code (enclosed between the curly braces) as long as the
Boolean condition is found to be true.
while { $p > 0 } {
…
}
catch statement
A "catch" statement suspends normal error handling on the enclosed Tcl command. If a variable name is also used,
then the return value of the enclosed Tcl command is stored in the variable.
catch { open “$inputFile” r } myresult
Handling exceptions (Tcl scripting)
To control the flow of the Designer software based on certain conditions (for example, success or failure of certain
commands), you can use the Tcl built-in catch command as follows:
if { [ catch {open_design $des_name.adb} ] } {
puts "Cannot open $des_name.adb"
export -format "log" -diagnostic $des_name.log"
exit 1
} else {
puts "Design $des_name.adb Successfully Opened"
}
## set layout mode to standard
layout -incremental "OFF"
if { [ catch {layout} ] } {
puts "Layout Failed"
export -format "log" -diagnostic $des_name.log"
exit 1
} else {
puts "layout successful"
export -format log "$des_name.log"
save_design "$des_name.adb";
close_design
}

Print statement and Return values
Print statement and Return values
Print Statement
Use the puts command to write a string to an output channel. Predefined output channels are “stdout” and “stderr.” If
you do not specify a channel, then puts display text to the stdout channel.
Note: Note: The STDIN Tcl command is not supported by Actel tools.
Example:
set a [ myprog arg1 arg2 ]
puts "the answer from myprog was $a (this text is on stdout)"
puts stdout “this text also is on stdout”
Return Values
The return code of a Tcl command is a string. You can use a return value as an argument to another function by
enclosing the command with square brackets [ ].
Example:
set a [ prog arg1 arg2 ]
exec $a
The Tcl command “exec” will run an external program. The return value of “exec” is the output (on stdout) from the
program.
Example:
set tmp [ exec myprog ]
puts stdout $tmp
Running Tcl scripts from the GUI
Instead of running scripts from the command line, you can use Execute Script dialog box to run a script in the Project
Manager or Designer.
To run a Tcl script from the GUI:
1.
In Project Manager, from the Project menu choose Execute Script.
In Designer, from the File menu choose Execute Script. This opens the Execute Script dialog box (as shown in
the figure below).
Libero IDE v9.1 User’s Guide

Figure 113 · Execute Script Dialog Box
2.
Click Browse to display the Open dialog box, in which you can navigate to the folder containing the script file to
open. When you click Open, Designer enters the full path and script filename into the Execute Script dialog box
for you.
3.
In the Arguments edit box, enter the arguments to pass to your Tcl script as shown in the following sample
Execute Script dialog box. Separate each argument by a space character. For information about accessing
arguments passed to a Tcl script, see "Running Scripts from the command line."
Figure 114 · Execute Script Dialog Box Example
4.
Click Run.
Specify your arguments in the Execute Script dialog box. To get those argument values from your Tcl script, use the
following:
puts "Script name: $argv0"
puts "Number of arguments: $argc"
set i 0
foreach arg $argv {
puts "Arg $i : $arg"
incr i
}

Running Tcl scripts from the command line
Running Tcl scripts from the command line
You can run Tcl scripts from your Windows or Unix command line as well as pass arguments to scripts from the
command line.
To execute a Tcl script file in the Libero IDE Project Manager software from a shell command
line:
At the prompt, type the path to the Actel software followed by the word "SCRIPT" and a colon, and then the name of
the script file as follows:
<location of Actel software>\bin\libero SCRIPT:<filename>
where <location of Actel software> is the root directory in which you installed the Actel software,
and <filename> is the name, including a relative or full path, of the Tcl script file to execute. For
example, to run the Tcl script file "myscript.tcl", type:
C:\libero\designer\bin\libero SCRIPT:myscript.tcl
If myscript.tcl is in a particular folder named "mydesign", you can use SCRIPT_DIR to change the current
working directory before calling the script, as in the following example:
C:\libero\designer\bin\libero SCRIPT:myscript.tcl "SCRIPT_DIR:C:\actelprj\mydesign"
To execute a Tcl script file in the Designer software from a shell command line:
At the prompt, type the path to the Actel software followed by the word "SCRIPT" and a colon, and then the name of
the script file as follows:
<location of Actel software>\bin\designer SCRIPT:<filename>
where <location of Actel software> is the root directory in which you installed the Actel
software, and<filename>is the name, including a relative or full path, of the Tcl script file to
execute.
For example, to run the Tcl script file named "myscript.tcl" from the command line, you
can type:
C:\libero\designer\bin\designer SCRIPT:myscript.tcl
If myscript.tcl is in a particular folder named "mydesign", you can use SCRIPT_DIR to change the current
working directory before calling the script, as in the following example:
C:\libero\designer\bin\designer SCRIPT:myscript.tcl "SCRIPT_DIR:C:\actelprj\mydesign"
To pass arguments from the command line to your Tcl script file:
At the prompt, type the path to the Actel software followed by the SCRIPT argument. Enclose the entire argument
expression in double quotes:
<location of Actel software>\bin\designer "SCRIPT:<filename arg1 arg2 ...>"
where <location of Actel software> is the root directory in which you installed the Actel
software, and <filename arg1 arg2 ...>is the name, including a relative or full path, of the
Tcl script file and arguments you are passing to the script file.
For example,
C:\libero\designer\bin\designer "SCRIPT:myscript.tcl
one two three"
To obtain the output from the log file:
At the prompt, type the path to the Actel software followed by the SCRIPT and LOGFILE arguments.
<location of Actel software>\bin\designer "SCRIPT:<filename arg1 arg2 ...>"
LOGFILE:<output.log>
Libero IDE v9.1 User’s Guide
335
TCL Command Reference
where <location of Actel software> is the root directory in which you installed the Actel
software, <filename arg1 arg2 ...>is the name, including a relative or full path, of the Tcl
script file and arguments you are passing to the script file, and output.log is the name of
the log file.
For example,
C:\libero\designer\bin\designer "SCRIPT:myscript.tcl
one two three" "LOGILE:output.log"
Exporting Tcl scripts
You can write out a Tcl script file that contains the commands executed in the current session. You can then use this
exported Tcl script to re-execute the same commands interactively or in batch. You can also use this exported script to
become more familiar with Tcl syntax.
You can export Tcl scripts from the Project Manager or Designer; the actions are the same.
To export a Tcl session script from the Project Manager or Designer:
1.
From the File menu, choose Export>Script Files. The Export Script Files dialog box appears.
2.
From the Save in drop-down menu, navigate to the folder in which you want to save the script files.
3.
Type a filename for this Tcl script file.
4.
Click Save. The Script Export Options dialog box appears
Figure 115 · Script Export Options
5.
Check the Include Commands from Current Design [Project] Only checkbox. This option applies only if you
opened more than one design or project in your current session. If so, and you do not check this box, Project
Manager / Designer exports all commands from your current session.
6.
Select the radio button for the appropriate filename formatting. To export filenames relative to the current
working directory, select Relative filenames (default) formatting. To export filenames that include a fully
specified path, select Qualified filenames (full path; including directory name) formatting.
336
Libero IDE v9.1 User’s Guide

Choose Relative filenames if you do not intend to move the Tcl script from the saved location, or Qualified
filenames if you plan to move the Tcl script to another directory or machine.
7.
Click OK.
Project Manager / Designer saves the Tcl script with the specified filename.
Note: Notes:
•
When exporting Tcl scripts, Project Manager and Designer always encloses filenames in curly braces to ensure
portability.
•
Project Manager and Designer software do not write out any Tcl variables or flow-control statements to the
exported Tcl file, even if you had executed the design commands using your own Tcl script. The exported Tcl
file only contains the tool commands and their accompanying arguments.
extended_run_gui - Designer Only
This script is used to reproduce the GUI behavior and is more suited for running through Designer or inside another
Designer TCL script.
The only difference from the extended_run_shell Tcl script is that the extended_run_gui.tcl script does not need the –
adb argument and assumes that the design is already saved and open.
extended_run_gui.tcl [-n numPasses] [-starting_seed_index numIndex] [-save_all] [compare_criteria value] [-c clockName] [-analysis value] [-slack_criteria value] [timing_driven|-standard] [-stop_on_success] [-run_placer value] [-place_incremental value]
[-route_incremental value] [-effort_level numLevel] [-timing_weight numWeight] [placer_high_effort value] [-mindel_repair value] [-power_driven value]
To invoke extended_run_gui from Designer:
1.
Open an *.adb file in Designer.
2.
From the File menu, select Execute Script. This opens the Execute Script dialog box.

This is the default.
tns
Sets the timing violations criteria to total negative slack. For each pass obtains the sum
of negative slacks from the first 100 paths from the timing violations report. The largest
value out of all passes will determine the best pass. If no negative slacks exist for a pass,
then the worst slack is used to evaluate that pass
[-stop_on_success]
Applies only when the timing violations comparison criteria is used. The type of timing violations (slacks) is
determined by the -analysis option. Stops performing remaining passes if all timing constraints have been met (when
there are no negative slacks reported in the timing violations report).

TCL Command Reference
Tcl command documentation conventions
The following table shows the typographical conventions used for the Tcl command syntax.
Syntax Notation
Description
command argument
Commands and arguments appear in Courier New typeface.
variable
Variables appear in blue, italic Courier New
typeface. You must substitute an appropriate value
for the variable.
[-argumentvalue]
Optional arguments begin and end with a square bracket with one
[variable]+
exception: if the square bracket is followed by a plus sign (+), then
users must specify at least one argument. The plus sign (+) indicates
that items within the square brackets can be repeated. Do not enter
the plus sign character.
Note: Note: All Tcl commands are case sensitive. However, their arguments are not.
Examples
Syntax for the get_defvar command followed by a sample command:
get_defvar variable
get_defvar “DESIGN”
Syntax for the backannotate command followed by a sample command:
backannotate -name file_name -format format_type -language language -dir directory_name [netlist] [-pin]
backannotate -dir \
{..\design} -name "fanouttest_ba.sdf" -format "SDF" -language "VERILOG" \
-netlist
Wildcard Characters
You can use the following wildcard characters in names used in Tcl commands:
Wildcard
348
What it Does
\
Interprets the next character literally
?
Matches any single character
*
Matches any string
Libero IDE v9.1 User’s Guide
Tcl command documentation conventions
Wildcard
[]
What it Does
Matches any single character among those listed between brackets (that is,
[A-Z] matches any single character in the A-to-Z range)
Note: Note: The matching function requires that you add a slash (\) before each slash in the port, instance, or net
name when using wildcards in a PDC command and when using wildcards in the Find feature of the
MultiView Navigator. For example, if you have an instance named “A/B12” in the netlist, and you enter that
name as “A\\/B*” in a PDC command, you will not be able to find it. In this case, you must specify the name as
A\\\\/B*.
Special Characters [ ], { }, and \
Sometimes square brackets ([ ]) are part of the command syntax. In these cases, you must either enclose the open and
closed square brackets characters with curly brackets ({ }) or precede the open and closed square brackets ([ ])
characters with a backslash (\). If you do not, you will get an error message.
For example:
pin_assign -port {LFSR_OUT[0]} -pin 15
or
pin_assign -port LFSR_OUT\[0\] -pin 180
Note: Note: Tcl commands are case sensitive. However, their arguments are not.
Entering Arguments on Separate Lines
To enter an argument on a separate line, you must enter a backslash (\) character at the end of the preceding line of the
command as shown in the following example:
backannotate -dir \
{..\design} -name "fanouttest_ba.sdf" -format "SDF" -language "VERILOG" \
-netlist

rollback_constraints_from_adb
You can enter pin constraints from Project Manager by either using the text editor to add them to a PDC file or by
using the I/O Attribute Editor..
Once you have imported I/O constraint files into Designer, you can modify the constraints with the MultiView
Navigator. After modifying the constraints, you can import them back into Project Manager to replace the existing
constraints.
When you use the Rollback Constraints feature, Project Manager opens the ADB file, exports the PDC file, and
then replaces it with the specified PDC file.

Tcl command documentation conventions
Syntax Notation
Description
command argument
Commands and arguments appear in Courier New typeface.
variable
Variables appear in blue, italic Courier New
typeface. You must substitute an appropriate value
for the variable.
[-argumentvalue]
Optional arguments begin and end with a square bracket with one
[variable]+
exception: if the square bracket is followed by a plus sign (+), then
users must specify at least one argument. The plus sign (+) indicates
that items within the square brackets can be repeated. Do not enter
the plus sign character.
Note: Note: All Tcl commands are case sensitive. However, their arguments are not.
Examples
Syntax for the get_defvar command followed by a sample command:
get_defvar variable
get_defvar “DESIGN”
Syntax for the backannotate command followed by a sample command:
backannotate -name file_name -format format_type -language language -dir directory_name [netlist] [-pin]
backannotate -dir \
{..\design} -name "fanouttest_ba.sdf" -format "SDF" -language "VERILOG" \
-netlist
Wildcard Characters
You can use the following wildcard characters in names used in Tcl commands:
Wildcard
What it Does
\
Interprets the next character literally
?
Matches any single character
*
Matches any string
[]
Matches any single character among those listed between brackets (that is,
[A-Z] matches any single character in the A-to-Z range)
Libero IDE v9.1 User’s Guide
401
Project Manager Tcl Commands
Note: Note: The matching function requires that you add a slash (\) before each slash in the port, instance, or net
name when using wildcards in a PDC command and when using wildcards in the Find feature of the
MultiView Navigator. For example, if you have an instance named “A/B12” in the netlist, and you enter that
name as “A\\/B*” in a PDC command, you will not be able to find it. In this case, you must specify the name as
A\\\\/B*.
Special Characters [ ], { }, and \
Sometimes square brackets ([ ]) are part of the command syntax. In these cases, you must either enclose the open and
closed square brackets characters with curly brackets ({ }) or precede the open and closed square brackets ([ ])
characters with a backslash (\). If you do not, you will get an error message.
For example:
pin_assign -port {LFSR_OUT[0]} -pin 15
or
pin_assign -port LFSR_OUT\[0\] -pin 180
Note: Note: Tcl commands are case sensitive. However, their arguments are not.
Entering Arguments on Separate Lines
To enter an argument on a separate line, you must enter a backslash (\) character at the end of the preceding line of the
command as shown in the following example:
backannotate -dir \
{..\design} -name "fanouttest_ba.sdf" -format "SDF" -language "VERILOG" \
-netlist

create_clock
Creates a clock constraint on the specified ports/pins, or a virtual clock if no source other than a name is specified.
create_clock -period period_value [-name clock_name]
[-waveform> edge_list][source_objects]
Arguments
-period period_value
Specifies the clock period in nanoseconds. The value you specify is the minimum time over which the clock
waveform repeats. The period_value must be greater than zero.
-name clock_name
Specifies the name of the clock constraint. You must specify either a clock name or a source.
-waveform edge_list
Specifies the rise and fall times of the clock waveform in ns over a complete clock period. There must be exactly two
transitions in the list, a rising transition followed by a falling transition. You can define a clock starting with a falling
edge by providing an edge list where fall time is less than rise time. If you do not specify -waveform option, the tool
creates a default waveform, with a rising edge at instant 0.0 ns and a falling edge at instant (period_value/2)ns.
source_objects
Specifies the source of the clock constraint. The source can be ports, pins, or nets in the design. If you specify a clock
constraint on a pin that already has a clock, the new clock replaces the existing one. You must specify either a source
or a clock name.
Supported Families

Arguments
-name name
Specifies the name of the clock constraint.
-source reference_pin
Specifies the reference pin in the design from which the clock waveform is to be derived.
-divide_by divide_factor
Specifies the frequency division factor. For instance if the divide_factor is equal to 2, the generated clock period is
twice the reference clock period.
-multiply_by multiply_factor
Specifies the frequency multiplication factor. For instance if the multiply_factor is equal to 2, the generated clock
period is half the reference clock period.
-invert
Specifies that the generated clock waveform is inverted with respect to the reference clock.
source
Specifies the source of the clock constraint on internal pins of the design. If you specify a clock constraint on a pin
that already has a clock, the new clock replaces the existing clock. Only one source is accepted. Wildcards are
accepted as long as the resolution shows one pin.

Description
Creates a generated clock in the current design at a declared source by defining its frequency with respect to the
frequency at the reference pin. The static timing analysis tool uses this information to compute and propagate its
waveform across the clock network to the clock pins of all sequential elements driven by this source.
The generated clock information is also used to compute the slacks in the specified clock domain that drive
optimization tools such as place-and-route.
Examples
The following example creates a generated clock on pin U1/reg1:Q with a period twice as long as the period at the
reference port CLK.
create_generated_clock -name {my_user_clock} –divide_by 2 –source [get_ports {CLK}]

constraint has priority over the existing constraint.
no
All existing timing constraints are replaced by the constraints in the newly
imported SDC file.
-merge_physical value
Specifies whether to preserve all existing physical constraints when you import a GCF or PDC file. Same as
selecting or unselecting the "Keep existing physical constraints" check box in the Import Files dialog box. The
following table shows the acceptable values for this option:
Value

Description
Designer preserves all existing physical constraints that you have entered either
using one of the MVN tools (ChipPlanner, PinEditor, or the I/O Attribute
Editor) or a previous GCF or PDC file. The software resolves any conflicts
between new and existing physical constraints and displays the appropriate
message.
no
All existing physical constraints are replaced by the constraints in the newly
imported GCF or PDC file.
-merge_all value

Exceptions
Your script -merge options vary according to family as shown below:
•
The -merge_timing, -merge_physical, and -merge_all arguments are available for IGLOO, Fusion, ProASIC3,
ProASICPLUS, ProASIC, and Axcelerator families.
•
For source SDC (no PDC/GCF) in eX and SX-A:

440
Libero IDE v9.1 User’s Guide
import_source
import_source -merge yes/no
...
import_source -merge_all yes/no
...
The eX and SX-A families do not support merging of physical constraints. For these families, in import_source, the
-merge_all and -merge options are mapped just to -merge_timing.
•
For constraints in ProASICPLUS:
import_source -merge_physical yes/no ...
import_source -merge_all yes/no ...
import_source -merge yes/no ...
ProASICPLUS and ProASIC support GCF, but the -merge option in the import_source only affects GCF in terms of
the physical constraints.
•
ProASIC does not support PreCompile import of the SDC files. The -merge_timing option has no effect on this
import_source for ProASIC. The -merge_all and -merge options map to -merge_physical for ProASIC in
import_source.
•
For IGLOO, Fusion, ProASIC3, ProASICPLUS, and Axcelerator:
import_source -merge_physical yes/no -merge_timing yes/no ...
import_source -merge_all yes/no
import_source -merge yes/no
...
...
The -merge_all and -merge options map to both -merge_physical and -merge_timing options for these families.

LOGFILE
The LOGFILE command is not a Tcl script. It runs in conjunction with your Tcl script and enables you to specify a
filename to which Designer will record/save a copy of the log messages generated in batch-mode (SCRIPT:...).
It is useful if you want to view the log after you run scripts in batch-mode on Windows.
For example, to run the script 'myscript.tcl' for Designer and save the log messages to a LOGFILE named 'mylog.txt',
use the command:
designer.exe SCRIPT:myscript.tcl LOGFILE:mylog.txt

Arguments
-nofix
Unlocks the pin assignment (by default, assignments are locked).
-port portname
Specifies the name of the port to which the pin is assigned.
-pin pin_number
Specifies the alphanumeric number of the pin to assign.
-iostd value
Sets the I/O standard for this pin. Choosing a standard allows the software to set other attributes such as the slew
rate and output loading. If the voltage standard used with the I/O is not compatible with other I/Os in the I/O
bank, then assigning an I/O standard to a port will invalidate its location and automatically unassign the I/O. The

Description
CM
RTSX-S devices only. An advanced integrated circuit (IC) manufacturing process
OS
technology for logic and memory, characterized by high integration, low cost, low
power, and high performance. CMOS logic uses a combination of p-type and n-
type metal-oxide-semiconductor field effect transistors (MOSFETs) to implement
logic gates and other digital circuits found in computers, telecommunications, and
signal processing equipment.
LVT (Low-Voltage TTL) A general purpose standard (EIA/JESDSA) for 3.3V
TL
applications. It uses an LVTTL input buffer and a push-pull output buffer.
PCI
A computer bus for attaching peripheral devices to a computer motherboard in a
local bus. This standard supports both 33 MHz and 66 MHz PCI bus applications.
It uses an LVTTL input buffer and a push-pull output buffer. With the aid of an
external resistor, this I/O standard can be 5V-compliant for most families,
excluding IGLOO, ProASIC3, SmartFusion and Fusion families.
Note: Note: The -iothresh attribute is also referred to as "Loading" in some families.
-slew value
Sets the output slew rate. Slew control affects only the falling edges. Rising edges are not affected. This attribute is
only available for LVTTL, PCI, and PCI outputs. For LVTTL, it can either be high or low. For PCI and PCIX, it
can only be set to high. The following table shows the acceptable values for the supported devices (IGLOO,
ProASIC3, SmartFusion, Fusion, ProASICPLUS, ProASIC, Axcelerator, RTAX-S, eX, and SX-A):

e
-out_load value
Indicates the output-capacitance value based on the I/O standard selected. This option is not available in software.
This attribute determines what Timer will use as the loading on the output pin and applies only to outputs. You can
enter a capacitive load as an integral number of picofarads (pF). The default is 35pF. This attribute is available only
for the following devices: ProASIC3, SmartFusion, Fusion, Axcelerator, SX-A, RTSX-S, and eX.
Supported Families
The first syntax statement for pin_assign supports all families. The second one supports only IGLOO, ProASIC3,
SmartFusion, Fusion, ProASICPLUS, ProASIC, Axcelerator, RTAX-S, eX, and SX-A.

set_clock_latency
Defines the delay between an external clock source and the definition pin of a clock within SmartTime.
set_clock_latency -source [-rise][-fall][-early][-late] delay clock
Arguments
-source
Specifies the source latency on a clock pin, potentially only on certain edges of the clock.
-rise
Specifies the edge for which this constraint will apply. If neither or both rise are passed, the same latency is applied
to both edges.
-fall
Specifies the edge for which this constraint will apply. If neither or both rise are passed, the same latency is applied
to both edges.
-invert
Specifies that the generated clock waveform is inverted with respect to the reference clock.
-late
Optional. Specifies that the latency is late bound on the latency. The appropriate bound is used to provide the most
pessimistic timing scenario. However, if the value of "-late" is less than the value of "-early", optimistic timing takes
place which could result in incorrect analysis. If neither or both "-early" and "-late" are provided, the same latency is
used for both bounds, which results in the latency having no effect for single clock domain setup and hold checks.
-early
Optional. Specifies that the latency is early bound on the latency. The appropriate bound is used to provide the most
pessimistic timing scenario. However, if the value of "-late" is less than the value of "-early", optimistic timing takes
place which could result in incorrect analysis. If neither or both "-early" and "-late" are provided, the same latency is

Description
Clock source latency defines the delay between an external clock source and the definition pin of a clock within
SmartTime. It behaves much like an input delay constraint. You can specify both an "early" delay and a"late" delay
for this latency, providing an uncertainty which SmartTime propagates through its calculations. Rising and falling
edges of the same clock can have different latencies. If only one value is provided for the clock source latency, it is
taken as the exact latency value, for both rising and falling edges.

None
Examples
The following example sets an early clock source latency of 0.4 on the rising edge of main_clock. It also sets a clock
source latency of 1.2, for both the early and late values of the falling edge of main_clock. The late value for the clock
source latency for the falling edge of main_clock remains undefined.

set_false_path
Identifies paths that are considered false and excluded from the timing analysis in the current timing scenario.
set_false_path [-from from_list] [-through through_list] [-to to_list]
Arguments
-from from_list
Specifies a list of timing path starting points. A valid timing starting point is a clock, a primary input, an inout port,
or a clock pin of a sequential cell.
-through through_list
Specifies a list of pins, ports, cells, or nets through which the disabled paths must pass.
-to to_list
Specifies a list of timing path ending points. A valid timing ending point is a clock, a primary output, an inout port,
or a data pin of a sequential cell.
Supported Families
IGLOO, ProASIC3, SmartFusion, Fusion, ProASICPLUS, ProASIC (for analysis), Axcelerator, RTAX-S, eX (through option), and SX-A (-through option)
Description
The set_false_path command identifies specific timing paths as being false. The false timing paths are paths
that do not propagate logic level changes. This constraint removes timing requirements on these false paths so that
they are not considered during the timing analysis. The path starting points are the input ports or register clock pins,
and the path ending points are the register data pins or output ports. This constraint disables setup and hold
checking for the specified paths.
The false path information always takes precedence over multiple cycle path information and overrides maximum
delay constraints. If more than one object is specified within one -through option, the path can pass through any
objects.
You must specify at least one of the –from, -to, or –through arguments for this constraint to be valid.
Examples
The following example specifies all paths from clock pins of the registers in clock domain clk1 to data pins of a
specific register in clock domain clk2 as false paths:
set_false_path –from [get_clocks {clk1}] –to reg_2:D

set_input_delay
Creates an input delay on a port list by defining the arrival time of an input relative to a clock in the current
scenario.
set_input_delay delay_value -clock clock_ref [–max] [–min] [–clock_fall] input_list
Arguments
delay_value
Specifies the arrival time in nanoseconds that represents the amount of time for which the signal is available at the
specified input after a clock edge.
-clock clock_ref
Specifies the clock reference to which the specified input delay is related. This is a mandatory argument. If you do
not specify -max or -min options, the tool assumes the maximum and minimum input delays to be equal.
-max
Specifies that delay_value refers to the longest path arriving at the specified input. If you do not specify -max or -min
options, the tool assumes maximum and minimum input delays to be equal.
-min
Specifies that delay_value refers to the shortest path arriving at the specified input. If you do not specify -max or min options, the tool assumes maximum and minimum input delays to be equal.
-clock_fall
Specifies that the delay is relative to the falling edge of the clock reference. The default is the rising edge.
input_list
Provides a list of input ports in the current design to which delay_value is assigned. If you need to specify more than
one object, enclose the objects in braces ({}).
Supported Families

Description
The set_input_delay command sets input path delays on input ports relative to a clock edge. This usually represents a
combinational path delay from the clock pin of a register external to the current design. For in/out (bidirectional)
ports, you can specify the path delays for both input and output modes. The tool adds input delay to path delay for
paths starting at primary inputs.
A clock is a singleton that represents the name of a defined clock constraint. This can be:
•
a single port name used as source for a clock constraint
Libero IDE v9.1 User’s Guide
519
Project Manager Tcl Commands
•
a single pin name used as source for a clock constraint; for instance reg1:CLK. This name can be hierarchical (for
instance toplevel/block1/reg2:CLK)
•
an object accessor that will refer to one clock: [get_clocks {clk}]
Examples
The following example sets an input delay of 1.2ns for port data1 relative to the rising edge of CLK1:
set_input_delay 1.2 -clock [get_clocks CLK1] [get_ports data1]
The following example sets a different maximum and minimum input delay for port IN1 relative to the falling edge
of CLK2:
set_input_delay 1.0 -clock_fall -clock CLK2 –min {IN1}
set_input_delay 1.4 -clock_fall -clock CLK2 –max {IN1}

Arguments
delay_value
Specifies a floating point number in nanoseconds that represents the required maximum delay value for specified
paths.
•
If the path starting point is on a sequential device, the tool includes clock skew in the
computed delay.
•
If the path starting point has an input delay specified, the tool adds that delay value to

Description
This command specifies the required maximum delay for timing paths in the current design. The path length for any
startpoint in from_list to any endpoint in to_list must be less than delay_value.
The timing engine automatically derives the individual maximum delay targets from clock waveforms and port input
or output delays.
The maximum delay constraint is a timing exception. This constraint overrides the default single cycle timing
relationship for one or more timing paths. This constraint also overrides a multicycle path constraint.
You must specify at least one of the –from, -to, or –through arguments for this constraint to be valid.
Examples
The following example sets a maximum delay by constraining all paths from ff1a:CLK or ff1b:CLK to ff2e:D with a
delay less than 5 ns:
set_max_delay 5 -from {ff1a:CLK ff1b:CLK} -to {ff2e:D}

Arguments
ncycles
Specifies an integer value that represents a number of cycles the data path must have for setup or hold check. The
value is relative to the starting point or ending point clock, before data is required at the ending point.
-setup
Optional. Applies the cycle value for the setup check only. This option does not affect the hold check. The default
hold check will be applied unless you have specified another set_multicycle_path command for the hold value.
-hold
Optional. Applies the cycle value for the hold check only. This option does not affect the setup check.
Note: Note: If you do not specify "-setup" or "-hold", the cycle value is applied to the setup check and the default
hold check is performed (ncycles -1).
-from from_list
Specifies a list of timing path starting points. A valid timing starting point is a clock, a primary input, an inout port,
or a clock pin of a sequential cell.
-through through_list
Specifies a list of pins or ports through which the multiple cycle paths must pass.
-to to_list
Specifies a list of timing path ending points. A valid timing ending point is a clock, a primary output, an inout port,

Description
Setting multiple cycle paths constraint overrides the single cycle timing relationships between sequential elements by
specifying the number of cycles that the data path must have for setup or hold checks. If you change the multiplier, it
affects both the setup and hold checks.
False path information always takes precedence over multiple cycle path information. A specific maximum delay
constraint overrides a general multiple cycle path constraint.
If you specify more than one object within one -through option, the path passes through any of the objects.
You must specify at least one of the –from, -to, or –through arguments for this constraint to be valid.

Arguments
delay_value
Specifies the amount of time before a clock edge for which the signal is required. This represents a combinational
path delay to a register outside the current design plus the library setup time (for maximum output delay) or hold
time (for minimum output delay).
-clock clock_ref
Specifies the clock reference to which the specified output delay is related. This is a mandatory argument. If you do
not specify -max or -min options, the tool assumes the maximum and minimum input delays to be equal.
-max
Specifies that delay_value refers to the longest path from the specified output. If you do not specify -max or -min
options, the tool assumes the maximum and minimum output delays to be equal.
-min
Specifies that delay_value refers to the shortest path from the specified output. If you do not specify -max or -min

If the checkbox is de-selected the dialog box displays all cores, including those already loaded into the Vault. The status
column indicates if a core has already been loaded.
Use the Filter to find any string that exists either in the core name or the Core Description. By default the filter
contains a beginning and ending ‘*’, so if you type ‘controller’ you get all cores with controller in the core name (case
insensitive search) or in the core description.
The colored icons indicate the license status. Blank means that the core is not license protected in any way. Colored
icons means that the core is license protected, with the following meanings:
Green Key - Fully licensed; supports the entire design flow.
Yellow Key - Has a limited or evaluation license only. Precompiled simulation libraries are provided, enabling the
core to be instantiated and simulated within the Actel Libero Integrated Design Environment (IDE). Using the
Evaluation version of the core it is possible to create and simulate the complete design in which the core is being
included. The design is not synthesizable (RTL code is not provided). No license feature in the license.dat file is
needed to run the core in evaluation mode. You can purchase a license to generate an obfuscated or RTL netlist.
