Embedded Flash Memory (NVM) Content
The NVM content dialog is divided into two sections. The top section shows the data that is retrieved from the PDB that you specified. The bottom section shows the data that is retrieved from the actual device. The
View Flash Memory Content diagnostic enables you to:
•
View content of Flash Memory pages (as shown in the figure below)
•
Compare device content with original design content (requires a PDB that contains your EFC data)
• Check page status and identify if a page is corrupted or if the write count limit has exceeded the 10-
year retention threshold
Fusion Devices: Choose your block from the From block dropdown list This action populates the Select dropdown list with the names of the clients in the selected block that is configured in the Flash Memory
System Builder.
SmartFusion Devices: Block selection is unused and unavailable.
Choose a client name from the Select dropdown list and click Read from Device to view the values. You can also view a specific page range by selecting the <Page Range> option in the Select dropdown list and then specifying the start page and the end page.
You must click Read from device each time you specify a new page range to update the view.
If you do not have your original design programming database (PDB) file, then you can also examine and retrieve a range of pages. Specify a page range if you wish to examine a specific set of pages.

Embedded Flash Memory: Browse Retrieved Data
The retrieved data table displays the content of the selected client or the page range selection. Corrupted pages content is displayed in red. Read-only page content, corresponding to clients defined with the Prevent read option in Flash Memory System Builder, is displayed on gray background. If content cannot be read
(e.g. pages are read-protected, but security has been erased), it is displayed as XX. The mouse tooltip summarizes abnormal content status (as shown in the figure below).
The corresponding page number and address (relative to the current block) are displayed in the left column.
The client size specified in the Flash Memory System Builder is shown at the top of the content table.
In the Retrieved Data View you can enter an Address value (such as 0010) in the Go to Address field and click the corresponding button to go directly to that address.
Click View Detailed Status for a detailed report on the page range you have selected.
For example, if you want to view a report on pages 1-3, set the Start Page to 1, End Page to 3 and click
Read from Device, then click View Detailed Status; the figure below is an example of the data for a specific page range.

After you retrieve the data from the device, the Compare Client Content button enables you to compare the content of the selected client from the device with the original programming database (PDB) file. The differences are shown in the Compare Memory Client dialog (as shown in the figure below).
NOTE: This option is not available when you select to retrieve the data based on a page range.

FlashROM Content Dialog Box
Enables you to view the physical blocks in your FlashROM and the client partitions specified in the original design content (requires a PDB that contains your UFC data). If the project’s PDB does not contain UFC data, only the physical blocks are displayed.
Scroll through the table to view the Words and Pages for your physical blocks.
The Client Partitions section lists the names and configuration details of the clients set up in the FlashROM
Builder. It automatically finds all mismatched client regions. To view the differences between a client and the device content, select a region row in the Client Partitions table. This action will highlight the corresponding device content in the Physical Blocks table. The mismatch details are displayed below the Client Partitions table.
To copy to clipboard the content of the Physical Blocks table, select one or more cells in the table and type
Ctrl+C.

Debug FPGA Array – SmartFusion2, IGLOO2, and RTG4 devices have built in probe points that greatly enhance the ability to debug logic elements within the device. The enhanced debug features implemented into the devices give access to any logic element and enable designers to check the state of inputs and outputs in real time. Live Probe and Active Probe are only available for the SmartFusion2, IGLOO2, and
RTG4 families.
• With
Live Probe , dedicated probes (two for SmartFusion2/IGLOO2 and one for RTG4) can be
configured to observe a Probe Point (any input or output of a logic element). The probe data can then be sent to an oscilloscope or even redirected back to the FPGA Fabric to drive a software logic analyzer.
•
Active Probe allows dynamic asynchronous read and write to a flip-flop or probe point. This enables
you to quickly observe the output of the logic internally or to quickly experiment on how the logic will be affected by writing to a probe point.
•
Memory debug lets you perform dynamic asynchronous reads and writes to a micro SRAM or large
SRAM block so you can quickly verify if the content of the memory is changing as expected.
•
Probe Insertion lets you route certain nodes (or debug points) in the FPGA design to the external world
through unused I/Os. You can attach an oscilloscope/logic analyzer to monitor them as live signals.
Debug SERDES - Enables you to examine and debug the SERDES blocks in your design. You can
configure your SERDES debug
, and run PRBS
and Loopback tests .
File Menu
The File Menu lets you execute SmartDebug-specific Tcl scripts (File > Execute Script) and export
SmartDebug-specific commands to a script file (File > Export Script File). You may pass the Tcl script to
SmartDebug for batch-mode execution from Libero. Refer to run_tool (SmartFusion2, IGLOO2 and RTG4) for details.
View Log
SmartDebug displays the Log Window by default when it is invoked. To suppress the Log window display, select the View menu and toggle View Log.
The Log Windows contains four tabs:
• Message window – displays standard output messages
• Errors window – displays error messages
• Warnings windows – displays warning messages
• Info window – displays general information
Using SmartDebug with SmartFusion2 and IGLOO2
The most common flow for Device Debug is:
1. Create your design . You must have a FlashPro programmer connected in order to use SmartDebug.
2. Expand Debug Design and double-click Smart Debug Design in the Design Flow window.
SmartDebug opens for your target device.
3. Click View Device Status to view the device status report and check for issues.
4. Examine individual silicon features, such as FPGA debug.
