3. In the Link section, specify the lane width of the PCI Express link to be analyzed. The rest of the settings in this section can be left at the factory defaults for most
PCI Express systems.
4. For multi‐lane PCI Express links, the Analyzer needs to observe link training in order to record link traffic correctly. If link training (or re‐training) is not easily controllable for the devices under test, the Analyzer includes the capability to force link training by disconnecting and reconnecting the PCI Express link.
Note:
For x1 PCI Express links, it is not necessary for the Analyzer to observe link training in order to record link traffic; this step may be skipped.
5. Click OK at the bottom of the Recording Options dialog to apply the Analyzer recording settings specified.
6. Click the Record button.
4.10.1 Stopping a Recording
You can stop the recording process at any time by pressing the Stop button . This causes the Analyzer to stop the recording and upload the CATC Trace to the host machine.
If you press the Stop button again, the Analyzer temporarily halts the upload process and opens the following dialog box.
Figure 4.18: Abort Upload
This dialog presents options for stopping, continuing, or aborting the upload:
Stop: Aborts further CATC Trace upload and displays whatever data that has already been uploaded.
Continue: Resumes the upload. This command tells the Analyzer to finish uploading whatever CATC Trace data is still in its buffer.
Flush: Flushes the CATC Trace without saving or displaying it.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 43
Teledyne LeCroy PCIe Protocol Suite Files
If you allow the traffic data to be uploaded, it is automatically saved on the host machine’s hard drive as a file named data.pex or the name you assign as the default filename in the recording options.
4.10.2 Saving a Recording
1. To save a current recording for future reference, select Save As from the File menu.
2. Give the recording a unique name, then save it to the appropriate directory.
4.11 PCIe Protocol Suite Files
The PCIe Protocol Suite software creates and uses different kinds of files:
CATC Trace Files: Recorded traffic
Recording Options Files: Configuration file that contains the various options selected in the Recording Options dialog to configure the recording
Display Options Files: Configuration file that contains the options selected in the
Display Options dialog to configure how traffic is displayed
4.11.1 CATC Trace Files
PCIe Protocol Suite records PCI Express traffic into a CATC Trace file with the default name
data.pex or any other that you specified in the Recording Options. This file is overwritten with new data each time PCI Express traffic is recorded.
If you want to save a CATC Trace, use the File > Save As function. This option allows you to save the current CATC Trace to a unique file name, thereby ensuring that it is not overwritten. This option also allows you to save a range of packets in a CATC Trace file.
You can pre‐define the name of the recorded CATC Trace file using the Trace Filename and Path option in Recording Options.
4.11.2 Recording Options Files
Recording Options files are created when you set recording options. These files use the
.rec extension and contain recording option information.
4.11.3 Display Options Files
Display Options files are created when you set display options. These files use the .opt extension and contain the display options information.
4.12 Saving CATC Trace Files
This section describes how to save a CATC trace file.
44 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Saving CATC Trace Files Teledyne LeCroy
4.12.1 Using the Save As Function
When you record a CATC Trace file, the Analyzer software provides a pre‐defined name to the CATC Trace file (data.pex or any other that you specified in the Recording Options). If you do consecutive recordings, each time the previous recording is overwritten. If you see a recording you want to analyze later, you need to give a unique name to the CATC Trace file, so it is not overwritten with the next recording.
Also, when you analyze a recorded CATC Trace file, you might be interested in preserving just a part of the PCI Express traffic that was recorded. If you save a portion of a CATC
Trace file, it can get significantly smaller, allowing you to attach it to an e‐mail.
To save a portion of a CATC Trace file or the whole file to a unique name, select Save As from the File menu (see
).
Figure 4.19: File Save As Dialog

Teledyne LeCroy Saving CATC Trace Files
If you want to give a unique name to the CATC Trace file, select the All option and keep
Rename original file checked. This is the default setting for the dialog.
4.12.2 Saving a Portion of a CATC Trace
If you want to save a portion of a CATC Trace file, select Save packet range. Enter starting and ending packet numbers in the From Packet and To Packet fields. By default, it has the numbers of the first and the last packets in the file. The software is going to save all the packets in specified range to the new file, unless you have Do not save hidden packets checked. In this case it is going to save all packets in the range, EXCLUDING the currently hidden packets.
46 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Exporting a CATC Trace File Teledyne LeCroy
4.12.3 Trace File Structure
The captured trace file has an extension of ".pex". When the trace file is loaded, additional decoding and data reduction is done which results in additional files of data which are placed in a folder of the same name as the trace file (with the extension
".tmp"). This allows the trace file to be loaded and displayed quickly during subsequent viewings.
When copying a trace file, or sending it to someone, you can chose to send just the .pex file. In that case, the software re‐generates the additional folder and files when the trace is first opened. The other choice is to send the additional folder with contents along with the .pex file, which will save the rebuilding effort when the file is opened again. The choice is up to the user. If you do NOT want these files kept, and don't mind the extra time it takes to re‐build these every time you load a trace file, then you can select this in the
Recording Options.
If the additional files ever become out of date (newer software structures from a new release, etc.) or if any of the files are lost or damaged, the software will rebuild a fresh version of the information.
4.13 Exporting a CATC Trace File
By default, PCIe Protocol Suite saves CATC Trace files in the .pex format. However, you can export a CATC Trace to a file in any of the following other formats:
Text
Comma Separated Value (CSV)
Generator file format
Exporting to Generator file format is a simple way to create a script file from your
CATC Trace. Only PCI Express packets will be exported to a script. All transaction levels, including supported SSD decodes, can be exported to Text or CSV Text.
To export a CATC Trace file, select File > Export.

CrossSync is Teledyne LeCroy’s analyzer synchronization solution that enables time‐ aligned display of protocol traffic from multiple daisy‐chained analyzers showing packet traffic from multiple high‐speed serial busses. A lightweight software control panel allows users to select analyzers for synchronization and manage the recording process. Captured traffic is displayed using the latest analyzer software (in separate windows) with all the protocol specific search and reporting features.
Captured packets are displayed in separate windows that share a common time scale.
Navigating the traffic in either direction will scroll to the same timestamp in a synchronized window. When using the CrossSync option, users can access the full complement of analysis capabilities available within the individual Teledyne LeCroy software. Search, reporting, and decoding all operate normally.
This feature is available with the Teledyne LeCroy PCIe Protocol Suite software application.
Launching the CrossSync Control Panel
To launch CrossSync from the PCIe Protocol Suite software application, select the ‘Launch
CrossSync Control Panel‘ entry in the ‘Setup’ menu (see the screen below). Or, you can launch CrossSync from the ‘Start’ menu.

5.7.1 Snapshot
A recording of a pre‐determined length. You set the recording length in the Buffer Size box. Recording begins when you click the Rec button on the toolbar and ends when the selected buffer size is filled or when you press the Stop button.
5.7.2 Manual Trigger
Recording begins when you select Start in the application. Pressing the Trigger button allows the Analyzer to finish recording by switching between the pre‐trigger buffer and the post‐trigger buffer. Recording continues until the post‐trigger buffer has been filled.
You can also end the recording immediately by pressing the Stop button in the application.
Note:
Consider that when filtering is enabled, pressing the Trigger button will not necessarily cause the post‐trigger buffer to fill automatically, due to packets being filtered and not stored. In this case you will have to use the Stop button to immediately end the recording.
5.7.3 Event Trigger
A recording that switches between the pre‐trigger buffer and the post‐trigger buffer when it is triggered by an event in the CATC Trace. An Event Trigger begins when you select Start in the application and ends when the specified triggering event occurs in the
CATC Trace or you press Stop. If an event triggers the end of the recording, the Analyzer records a predefined amount of post‐trigger data (specified by Trigger Position and Buffer
Size.)
You can also terminate an Event Trigger recording by pressing the Manual Trigger button on the front of the Analyzer. When the Manual Trigger button is pressed, the Analyzer continues to record until the specified post‐trigger buffer has been filled.
The Buffer Size allows the Analyzer to record traffic to its buffer and then upload the
CATC Trace to the host machine. Recordings are limited in size to the size of the Analyzer's buffer, see Figure 5.1: 2B (1 GB per direction, Upstream and Downstream).
The Buffer Size slide‐bar allows you to set the size of the recording buffer.
58 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Upload Size Teledyne LeCroy
Figure 5.4: Buffer Size Slide Bar
The size selection is per direction. For example, selecting 32 MB creates two memory areas of that size.
After you have set the Buffer Size, you must set the Recording type and Trigger position options. These options determine how the buffer is used.
Note:
The Buffer Size slide‐bar does not precisely portray the buffer size because of the way the packets are stored in the Analyzer’s memory.
Causes the Analyzer to upload a portion of the Analyzer's buffer. This option lets you look at part of the CATC Trace. Half of the uploaded CATC Trace is pre‐buffer and half post‐
trigger (See Figure 5.1 on page 54 : 2C).

Protocol Recording
Bit Tracer Recording
Figure 5.8: Recording Mode Options
5.11.1 Protocol Recording
In this mode of recording, the analyzer records traffic on the bus in a native PCIe protocol.
5.11.2 BitTracer Recording
When the Bit Tracer Recording box is checked, it allows you to select the Speed and the
Link Width from the drop‐down menu. Based on the Speed and Link Width selected you can select the Upstream and Downstream Symbol on which to trigger.
This option does not have Simple Mode and Advanced Mode. Therefore, Upload Size, the
Miscellaneous options, Auto‐Configure Lane Polarity, Auto Speed, and Auto Link are not available.
Note:
Leaving all the boxes unchecked results in no trigger in that direction. For more information, see
the next chapter, see the next chapter, “BitTracer Recording” on page 191 .
This Trigger Position slide‐bar lets you adjust the amount of recording buffer allocated to recording pre‐trigger and post‐trigger traffic (see
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Link Settings Teledyne LeCroy
Figure 5.9: Trigger Position Slide Bar
For example, if you set the Trigger Position to 90% Post‐Triggering Traffic, the Analyzer records 10% pre‐trigger traffic and 90% post‐trigger traffic.
Trigger Position is only available when Manual Trigger or Event Trigger is selected.
5.12.1 Viewing Legacy Multi-Segmented CATC Traces
Current PCIe Protocol Suite software handles traces as large as the maximum buffer size selected. It does not need to generate segmented traces, but is able to open segmented traces generated with older software versions. Simply open the *.pem extension file and the trace will be converted to a new format single trace. If you are opening a *.pex file part of a segmented trace, make sure not to update the file in order for the original segmented index to work properly.
The Link options panel allows you to manage links (see Figure 5.10 on page 62 ). You can
define the basic link parameters or leave it on Auto detect. The various link settings are described in this section (see
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 61
Teledyne LeCroy
Link Speed Displayed

62
Figure 5.10: Link Options for Summit T24
5.13.1 Speed
The Speed can be set at Auto, 5.0 GT/s, or 2.5 GT/s from the drop‐down menu. The default is Auto (see
: 3A or Figure 5.10 on page 62 left side).
Auto: When set to Auto, the hardware auto‐determines the speed.
5.0 GT/s or 2.5 GT/s: When set to a specific speed, Teledyne LeCroy’s software forces the hardware to record at that speed.
For Auto speed setting to work the polarity setting of lane 0 has to be correct. The polarity can be set manually if the link is already in L0 state, or, for automatic polarity detection, the bus has to go through a reset so the analyzer can track the polarity.
Note:
For certain build configurations speed option 5.0 GT/s may be disabled.

Link Settings Teledyne LeCroy
Note:
Selecting Auto in the Speed drop‐down list will set the correct speed even if the analyzer does not record a link training sequence.
5.13.2 Link Width
The Link Width sets the physical width of the link. Select the Link Width or select Auto
(see Figure 5.1 on page 54 : 3B or
right side). The available options
(and the default) will be shown according to the detected product.

Note:
If the bus goes to a link width different from the one selected as fixed option, the trace will be full of errors. The appropriate Auto option needs to be selected in this case.
Note:
Selecting Auto in the Link Width drop‐down list will find the correct link width even if the analyzer does not record a link training sequence and for links that are in low power states.
5.13.3 Upstream and Downstream
Gives you low‐level control over each link direction. The heading for these boxes indicates the port and/or unit to which the following options are applied based on the current
Analyzer configuration (see Figure 5.1 on page 54 : 3C and 3D).
Inhibit Channel: Do not record/upload this channel
Reverse Lanes: Reverse Lanes: Manual lane reversal. If Swizzling Config is set, the Reverse Lanes will not work if Auto is checked.
Invert Polarity
5.13.4 Reference Clock
If the PCI Express link under analysis uses spread‐spectrum clocking, then the Analyzer must use the external reference clock from the system. If the Device Under Test does not supply a reference clock, the internal reference clock in the Analyzer module can be used
instead (see Figure 5.1 on page 54 : 3E). Only the standard PCIe reference clock is
supported.
5.13.5 Disable Descrambling
If checked, causes the Analyzer to assume that none of the PCI Express traffic is scrambled. By default, the Analyzer determines the scrambling state of the devices under test (see
: 3F).
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 63
Teledyne LeCroy Link Settings
5.13.6 Auto-Configure Lane Polarity
Lets the Analyzer determine lane polarity (see Figure 5.1 on page 54
: 3G). Auto functions such as Auto Configure polarity rely on Gen1 or Gen2 training sequences to properly discover their values.
5.13.7 Ignore Idle Errors
When set the analyzer will not store errors in between packets in the memory. This option helps to preserve analyzer memory to store more packets in cases where memory efficiency is critical. This option can also be used to filter out Compliance Patterns (see
: 3H).
5.13.8 Swizzling Config...
The Swizzling Config dialog allows you to reconfigure the order of the US (UpStream) and
DS (DownStream) lanes. See
: 3I.
Figure 5.11: Swizzling Config Dialog
When the Auto‐Configure Lane Swizzle is checked, it is important to configure Lane 0. You can do so by manually dragging Lane 0 to the required position (see

5.14 Triggering
Triggering Options can be set in both Simple and Advanced Modes. The options in both modes are the same, only the GUI is different where shortcuts for the events are displayed in the Simple Mode for easy access (see Figure 5.2 on page 55 ).
In the Advanced Mode triggering is set up via the recording rules which allow greater flexibility to create advanced sequences you would like the analyzer to look for. These recording rules are not available in the Simple Mode. The Simple Mode allows you to simply define triggering by checking the boxes.

2. Drag the selected events from the Available Events area into either the Global State
Cell or the Sequence Cell (see
“Recording Rules Overview” on page 69
).
Global State Cell
If you want the Analyzer to always search for the event, place it in the cell marked
Global State.
Sequence Cell
To create an event sequence, place two or more events in the faintly marked cell that reads Drag an event here to add a new sequence. At this point, the selected events have no effect because an action has not been assigned.
3. To select a sub‐set of your selected event, right‐click it and choose Properties. A
Properties dialog opens that presents additional options. For example, if you open the Properties dialog for Errors, you can set the specific types of errors the Analyzer should look for.
4. Assign an action to the selected events by right‐clicking each of the events, selecting
Specify Action from the pop‐up menu, and assigning an action such as Trigger,

5.17 Resources
Events in Recording Rules are based on Resources. There are two types of Resources.
They are Packet Match Resources, and Basic Resources.
5.17.1 Packet Match Resource
Packet Match Resources are for the TLP, DLLP, TS1 and TS2 events as well as some of the storage protocol trigger options such as AHCI Register, NVMe Register, PQI Register and
SOP IU Type. A Packet Match Resource allows you to define not only packets but it also allows you to define each specific bit in a packet. In the Packet Match resource you can define the exact layout to the bit level so that the Analyzer can match the exact pattern that applies to a TLP, DLLP, TS1 or TS2 event.
To set a Packet Match Resource, click on the New Event button and select any of the options. In this case we have selected DLLP: InitFC1. The DLLP: InitFC1 displays in the
Available Events panel. Double‐click on the DLLP: InitFC1 to select the specific fields and go to the Layout tab to change the pre‐defined bits.

The cell marked Drag an event here to add another sequence is the Sequence State. In the Sequence State you can define a sequence of Events and Actions which the Summit
T24 Analyzer looks for at pre‐determined times. Sequences are chains of events culminating in a trigger or any other action. A sequence which is a separate chain of events can be created with up to 16 states. A state is an event condition with an action within a sequence. Once a Sequence State is added the cell marked will read Drag an

Teledyne LeCroy Filter Out
A filter causes the Analyzer to filter out specified events from the recording. If events are filtered out of the recording, they are excluded from the Analyzer's buffer and not simply hidden from the CATC Trace. The purpose of “filtering out” is to preserve recording memory so you conduct longer recording sessions and exclude events that do not interest you.
Filter-Out In Simple Mode
In Simple Mode you can filter out:
SKIP Ordered Sets
UpdateFC DLLP
Link Events (Link Up and Link Down)
CLKREQ#
WAKE#
You can also choose to Ignore Idle Errors. See Figure 5.40
.
92
Figure 5.40: Simple Mode: Filter Out
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Filter In Teledyne LeCroy
Note:
If you did Filter‐Out all the events shown above, you’d create an empty trace and get a warning
Filter-Out in Advanced Mode
To enable “filter‐out” in Advanced Mode, place an event button into either the Global
State cell or the Sequence cell, then right‐click the button and choose an Action (see previous topic).
From the sub‐menu, select Filter‐Out. See Figure 5.41
.
Figure 5.41: Filter Out Option
Note:
The Filter‐Out option is only available in the DLLP, TLP, TS1 and TS2 Ordered Sets, for Link Events
Enter/Exit Electrical Idle, WAKE# Asserted/Deasserted, or CLKREQ# Asserted/Deasserted.
Note:
If you did Filter‐Out all events (by mistake), you’d create an empty trace and get a warning
“Filter in” is the logical opposite of “Filter Out”. In this case, you are specifically interested in capturing specific events or traffic and ignoring everything else. If events are filtered in to the recording, they are included in the Analyzer's buffer. The purpose of “filtering in” is to preserve recording memory so you conduct longer recording sessions and include only events that interest you. Filter in is only available in Advanced Mode.
As an example, let’s say you want to capture Any DLLP and Any NVMe:ACQ Commands.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 93
Teledyne LeCroy Filter In
First switch to Advanced Mode.
To enable “Filter‐In” place an event button (DLLP ‐> Any DLLP) into the Global State cell, then right‐click the button and choose an Action. From the sub‐menu select Filter‐In.
Then select NVMe under New Event and NVMe Register:ACQ and place that event into the Sequence 1, State 1 cell. Then right‐click the button and choose an Action. From the sub‐menu select Filter‐In. See Figure 5.43 on page 95 .
Figure 5.42: Filter In Option
Note:
When a Filter‐In is selected the analyzer filters out everything else by default.
Valid Configuration
In this case, you have chosen a Global State Filter‐In on any DLLP and Sequence 1, State 1 to have an NVMe Command:ACQ Filter‐In. This is a valid configuration as shown in
Figure 5.43
.

96
Figure 5.44: Warning Message for Invalid Configuration
The analyzer is warning you that you’ve set a Global Rule to Filter‐Out Any DLLP and that condition will filter out the NVMe:ACQ Command you’re looking for. So the recording rules have to be consistent. You’d get the same message if you set Any DLLP to Filter‐In but set the NVMe:ACQ Command to Filter‐Out. The warning message would pop up and if you hit OK, the Config is Invalid message will light up. See Figure 5.45 on page 97 .

5.24 Counter
Counters can be created for any specific event or for multiple events. Counters function similar to an event and are independent of the event, thus allowing greater flexibility. You can select a counter for any event and if both channels are selected you can set the counter to count upstream and downstream. Counters can be reset providing further flexibility. The counter once set lives in the State. In an Advance to Sequence state once the action proceeds from one sequence state to the next, the counter in the preceding state will stop and the counter in the current state will start.
There are two Counters for the Global State and four Counters for the Sequence State.
Note:
It is an invalid configuration for some events when you try and set a counter and timer when both channels are selected.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Counter Teledyne LeCroy
The counters have different colors for the Global State and Sequence State. Each color
signifies a different meaning in the Global and Sequence states (see Figure 5.55 on page 107 ).
Note:
Global timers/counters can be used by events from any direction as long as the events occur more than 380 ns apart. State timer/counters can be controlled only from one direction not both, meaning starting, reset and incrementing must be done from events occurring in the same direction of the selected timer/counter.

Note:
Listed below are some of the considerations to note about the counter functionality
1. If a counter is reset, it will restore to it's original value, in this case the value defined by the user.
2. Resetting a counter will stop it and set it to it's original value.
3. Local counters for a particular state will automatically reset if the sequencer advances to another state. Example: "Counter A" in State 1 and "Counter A" in State
2 are different timers not related to each other.
4. Local counters are controlled by events defined in the same state where the counters are defined.
5. In case of competing actions to control global counters using the same event from global and local states, the control from local states takes priority.

The Summit T24 analyzer can be optimized for specific DUT signal characteristics. The auto calibration feature in the Probe Settings allows for better signal recovery. There are
16, 0 db to 15 db, internal equalization modes in the analyzer hardware that boost the high frequency content of the captured signal. This equalization does not impact the signal to the DUTs, but helps in ‘opening the eye’ of the captured signal, so that the internal logic can capture PCIe frames. The system is designed to allow you to manually set the equalization to one of the sixteen modes for the CTLE values and one of the eight modes for the DFE values or choose to run an automated algorithm, internal to the analyzer. This automated calibration sets the optimized values for each of the PCIe captured lanes, provided that the signal at the analyzer input is stable.
Two lane settings can be configured, CTLE and DFE (Decision Feedback Equalization). CTLE is two dimensional and is set based on the least number of errors returned. DFE is three dimensional and is set based on the least number of errors returned by both CTLE and
DFE.

Decoding Traffic Teledyne LeCroy
The PCIe Protocol Suite software has several decode levels:
6.13.1 Packet
Packet level decode includes all TLP packets, DLLP packets, and all ordered sets.
Note: The PCI‐E 3.0 (and 2.1 with Errata) specifications state that there are two formats of the AER capability structure, and the AER_CAP_VER field indicates if format 1 or format 2 is used.
The difference between format 1 and format 2 is whether or not the TLP Prefix Header section is present in the AER capability, even if it is not actually implemented.
This means that:
If AER_CAP_VER = 1 and it is not a Root Port or RC Event Collector, there are 11
DWs (00h to 24h)in the total AER Capability structure.
If AER_CAP_VER = 1 and it is a Root Port or RC Event Collector, there are 14 DWs
(00h to 34h)in the total AER Capability structure.
If AER_CAP_VER = 2 then, there are 18 DWs (00h to 44h) in the total AER Capa‐ bility structure.
In fact, there are PCI‐E 3.0 compliant devices that have AER_CAP_VER=1.
Example H/W:
A PCI‐E 3.0 device that supports Multiple Header Recording, but does NOT support TLP
Prefixes. This device is allowed to have AER_CAP_VER=1, and
Multiple_Header_Recording_Capable=1
Therefore, the Teledyne LeCroy software decodes the
Multiple_Header_Recording_Capable field regardless of the value of AER_CAP_VER.

Teledyne LeCroy Decoding Traffic
6.13.2 Link
Link level decode is composed of TLP packets matched with a corresponding ACK or
NAK coming from the opposite direction.
6.13.3 Split
Split level decode is composed of two Link transactions, the Request TLP and the
Completion TLP from the other direction.

Decoding Traffic Teledyne LeCroy
6.13.4 NVMe
To decode the NVMe protocol there are two levels available: NVMe Transaction level, which decodes the individual NVMe transactions from the PCI Express protocol and
NVMe Command level, which gathers NVMe transactions into a single command. If the top level button is selected, it will decode the NVMe Command level directly.
The NVMe Transaction level option displays NVMe transactions. PCIe Protocol Suite decodes the storage commands starting from lower PCI Express Transaction Layer decodes. In the case of NVMe, it will decode first the Packet Level, then the Link
Transaction level, then the Split Transaction Level and finally the NVMe Transaction decode level.
The NVMe Command level option displays NVMe Commands. The NVME commands decode all the lower level decodes first.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 137
Teledyne LeCroy Decoding Traffic
Note:
As of software version 7.34, the NVMe decoding will be performed properly even if the ACK
DLLPs have been filtered.
Note:
As of software version 7.34, once the NVMe decoding has been applied, it will be kept in a
separate temporary file not the Trace file (see “Trace File Structure” on page 47 ). The next
time the trace is opened for review there will be no need to re‐decode, making opening of the file in NVMe mode faster.
Note:
As of software version 7.36 Beta, the NVMe decoding can handle multiple controller resets within the same recording.
NVMe: Device ID and Model Name Decoded
As of software version 7.34, the Device ID and Device Model Name field is displayed in the decoded command (see Figure 6.14
and Figure 6.15 on page 139 ).
Figure 6.14: Device ID and Model Number Decoded from NVMe Trace
The trace must contain the device enumeration sequence so the decoding picks up the associated base addresses and NVMe transactions can be properly decoded. If the enumeration sequence is not available the base addresses must be manually entered in the
PCIe SSD Configuration dialog from the Tools menu. See Figure 6.15 on page 139 .

BitTracer Recording
Note:
BitTracer Recording is an optional feature.
The Summit T24 analyzer has an optional BitTracer data capture mode, which captures bi‐ directional link traffic in raw format. The BitTracer recording mode captures and displays traffic before lane‐to‐lane de‐skew operations and before descrambling of 10b bytes. The
BitTracer mode includes support for multiple logical links (bifurcations) on a single physical link.
The BitTracer recording mode has its own user interface, which provides characterizations of link traffic that are not available in the standard protocol analyzer mode.
You can export BitTracer recordings for viewing in CATC Trace format.
Note:
This feature can be included at initial purchase or added in the field with a software upgrade license. To obtain a software license key to add this feature, contact Teledyne LeCroy.
Lane Deskew Bypass in Recording Options prevents lanes from being bonded by the analyzer, allowing you to troubleshoot problems with physical layer.
9.1 Enabling BitTracer Recording
To enable the BitTracer recording mode, open the Recording Options.
In the Target Analyzer section of the General tab, select Summit T24.
In the Recording Mode section, select Bit Tracer Recording.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 191
.
Teledyne LeCroy Views Available for Captured Data
In Bit Tracer Recording, you can use the Snapshot, Manual Trigger, and Event Trigger recording types.
Note:
You can also use other standard Recording Options, such as Link Width, Buffer Size, and Lane
Polarity Settings, to characterize the link.
9.2 Views Available for Captured Data
BitTracer mode displays captured data lane‐by‐lane and byte‐by‐byte in each direction
(upstream and downstream), with the time scale progressing left to right.
192
Other views are provided for timing measurements, marker placement, physical layer errors, captured symbol types, packets, events, and decoding of ordered sets and packets. You can view any or all displays simultaneously, using the Windows selection in the View menu.
By default, BitTracer recordings display captured data in time de‐skewed format, across all lanes for both directions. But it is possible, for debugging purposes, to bypass this de‐ skew using the Lane Deskew Bypass check box in Recording Options.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Data Display Formats Teledyne LeCroy
When lanes are not de‐skewed, individual bytes are as they were captured on the recorded link, before the receiver device on the link (or the receiver logic on the PCIe
Protocol Suite analyzer) has performed lane‐to‐lane de‐skew operations.
You can manually skew the captured data, left or right, in increments of one symbol time, using the associated toolbar buttons.
You can automatically de‐skew an entire lane direction. First, left‐click on the direction in the data window. Then right‐click to display a popup menu. Then select Auto De‐Skew.
You can de‐skew only one direction for each right‐click operation. To automatically de‐ skew the opposite direction, first left‐click on that direction in the data window.
Note:
The skew observed in the bit tracer is the actual skew of the lanes in the link plus the skew introduced by the analyzer interface. The De‐skew Bypass option is not intended for skew measurements or estimations.
To display traffic in K/D symbol (with Running Disparity indicated), scrambled, descrambled, 10‐bit, and Binary code formats:
Use the toolbar.

LFSR value) in pop‐up list.
194
Note:
Descrambled values can only be displayed after the first recorded skip ordered set. Data prior to the skip is displayed in scrambled values, due to the unknown LFSR.
Note:
For Binary Data Display Format, bits are shown in order of transmission on the bus.
9.5 Color-Coding of BitTracer Contents
To increase visual understanding of BitTracer displays, different symbol types have color‐ coding:
Presence or non‐presence of a lane’s byte‐lock
Idle data characters (D0.0)
K codes
Invalid 10b symbols
Signal presence
Background of the Markers Bar (see
)
(color coded according to traffic speed).
All symbols of a TS1/TS2 ordered set
By default, these color selections match the standard color selections used in the
CATC Trace format. You can modify them in the Display Options menu, accessible from the Main toolbar or the Setup menu.

Synchronize Trace View. Synchronizes the Trace View and Link Tracker windows so that a move in one window repositions the other.
Because of the differences in scale and logic between the Link Tracker and
Trace view window, scrolling produces different effects depending on which window is being scrolled.
Scrolling in the CATC Trace window causes the Link Tracker window to rapidly jump from event to event. Long periods of idle time are thus skipped.
Scrolling in the Link Tracker window, in contrast, produces modest movements within the CATC Trace window.
Scrolling in the Link Tracker window causes the CATC Trace window to pause until the beginning of a packet is displayed. At that point, the CATC Trace window repositions itself. While scrolling long Idle periods or through the contents of a packet, the CATC Trace window does not move.

Select View > FC Credits Setup... displays the FC
Credit Setup dialog (see the following screen capture).
For each virtual channel that is present in the trace you need to specify the amount of available credits before the beginning of the trace. You can also specify the values of credit fields for UpdateFC packets before the beginning of the trace. If the values of the

Using the CATC Trace Navigator
10.8.4 To Determine Current Position
In addition to the two range delimiters, the slider has a blue current‐position indicator
(see above). The current‐position indicator shows where you are in the CATC Trace display with respect to the possible viewing range.
For example, suppose you set viewing range to packet 0 through packet 500 (the top range delimiter is at packet 0, and the bottom range delimiter is at packet 500). If you then move the current‐position indicator on the slider to midway between the top and bottom delimiters, then packet 250 appears in the middle of the CATC Trace display.
10.8.5 To Reset Navigator Range
You can reset the Navigator range using the toolbar Navigator Range button. Press the button to bring up the Navigator Range drop‐down menu (see

Set Range Near Packet xxx: Allows you to collapse the range so that only the packets immediately above and below the xxx packet are displayed. The xxx packet is whatever packet is currently at the top in the CATC Trace display.
Recently Used Ranges: Allows you to reset the range to any of a number of recently used (previously set) ranges.
10.8.6 Navigator Panes
You can display any combination of CATC Trace Navigator panes.
From left to right, the panes are: Pre/Post Trigger, Errors, Traffic Type, Traffic Speed, and
Link Width. Each pane represents the entire CATC Trace with respect to different types of information. The top of each pane represents the start of the CATC Trace file, and the bottom represents the end of the CATC Trace file.
Pre/Post Trigger: To view the trigger event in the CATC Trace and the relative size of pre‐trigger and post‐trigger portions of the CATC Trace. The two portions are set apart as different colors. The trigger event occurs at the point the two colors meet.
Errors: To view any errors in the CATC Trace. A thin red line represents each error in the pane.
Traffic Type: To view the types of packets that occur in the CATC Trace. A differ‐ ent color represents each packet type in the pane. The relative size of colored portions in the pane corresponds to the amounts of the various packet types in the CATC Trace. As described below, you can use the Navigator legend to change the types of packets that take precedence in the display.

Detail View Teledyne LeCroy priority of information displayed in the panes using the up and down triangles on the right.
10.8.10 Using the Legend to Show/Hide Navigator Panes
To use the legend to show/hide an entire pane, use the checkbox next to the name of each pane in the legend.
In the case of the Pre/Post Trigger and Errors areas, the action of show/hide in the legend is identical to that provided by CATC Trace Navigator pop‐up menus.
In the case of the Traffic Types pane, there is no equivalent show/hide available through the pop‐up menus.
10.8.11 Using the Legend to Set the Priority of Information Display
You can use the legend to set the priority of information displayed in the Pre/Post Trigger
Traffic Type panes. This is a two‐step process.
1. For a particular item in a pane, click the column next to the checkbox for the item.
That labels the item as currently active.
2. Next, use the up‐down at the lower‐right of the area to move the item higher or lower in priority.
In the case of the Traffic Type pane, priority determines display priority of each packet type. For portions of the CATC Trace that are dominated by a particular packet type, this setting no effect: only the color corresponding to that packet type is displayed in that portion of the pane. Suppose, however, that part of the CATC Trace includes equal or near equal numbers of several types of packets. In that case, you can use the legend to select which among those types is represented in that portion of the Traffic Types pane. This allows you to view only packets of interest in crowded portions of the CATC Trace display.

10.14 Using Unit Metrics
For every protocol unit at the Link or Split transaction level, PCIe Protocol Suite™ calculates and displays a set of metrics. Metrics are measurements of key operating parameters. You can use metrics to evaluate performance of traffic in the CATC Trace stream.
You can view metrics information in the CATC Trace display, the Traffic Summary window, and the Bus Utilization window.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Metrics Defined for Link Transactions Teledyne LeCroy
PCIe Protocol Suite defines different metrics for Link and Split transactions.
10.15 Metrics Defined for Link Transactions
Number of Packets: The total number of packets that compose this Link transac‐ tion.
Payload: The number of data payload bytes this Link transaction transferred.
Response Time: The time it took to transmit this Link transaction on the PE link, from the beginning of the first packet in the transaction to the end of the last packet in the transaction.
Data Throughput: The payload divided by response time, expressed in mega‐ bytes per second.
Note:
Usually, the Number of Packets metric for a link transaction is two (in case of explicit acknowledge) or one (in case of implicit acknowledge). However if Naks/link level retries are involved, this metric might be higher. As a result, the Number of Packets metric is useful in highlighting unusual link transactions.
10.15.1 Metrics Defined for Split Transactions
The following types of metrics currently are defined for Split transactions:
Number of Link Transactions: The total number of Link transactions that compose this
Split transaction.
Payload: The number of payload bytes this Split transaction transferred.
Response Time: The time it took to transmit this Split transaction on the PE link, from the beginning of the first packet in the Split transaction to the end of the last packet in the
Split transaction;
Data Throughput: The transaction payload divided by response time, expressed in megabytes per second.
Latency Time: The time measured from the end of the request transaction to the first completion transmitted in response to the request within this Split transaction.
Note:
The Number Of Link Transactions metric for a Split Transaction usually is two for a Configuration or IO request. It can be bigger then two for a Memory Read request.
10.16 Show Metrics in the CATC Trace Display
In the CATC Trace view display of Link Transaction or Split Transaction levels, all metrics information applicable to a specific protocol unit is displayed in a Metrics header. The header is located close to the end of the unit, in front of the Time cell. You can expand and collapse the header to show or hide the metrics information.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 241
Teledyne LeCroy Show Metrics in the CATC Trace Display
10.16.1 Collapsed Metrics Header Display
Following is a collapsed metrics display for a unit of Link Transaction. The collapsed header display shows only the metrics cell representing the Number of Packets (see the following figure).
Following is a collapsed metrics display for a unit of Split Transaction. The collapsed header display shows only the metrics cell representing Number of Link Transactions.
10.16.2 Metrics Tool Tip Display
In both CATC Trace level views, you can view the summary of all the unit metrics in the
Metrics header tool tip. To view the tool tip, simply place the mouse cursor over the
Metrics header. Following is the tool tip for a unit in the Link Transaction view.
242
Note:
The tool tip also presents information for time passed from the start of the recording till the beginning of this Link or Split Transaction.
10.16.3 Expanded Metrics Header Display
When you expand the Metrics header, the display creates a separate cell for each applicable metric:
The following is the expanded Metric header for a unit in the Split Transaction view.
The following is the expanded Metric header for a unit in the Link Transaction view.

Show Metrics in the Traffic Summary Window Teledyne LeCroy
Note:
Each of the metric cells pops up a tool tip window with the explanation of what the metric means.
10.17 Show Metrics in the Traffic Summary Window
Some of the Traffic Summary reports at the Link and Split Transaction levels are based on metrics collected for the corresponding protocol units in the CATC Trace.
10.17.1 Reports at Split Transaction Level
Split Transaction Performance: This report table groups the Split Transactions by
Requester‐Completer pair and displays Minimum/Average/Maximum data for Number Of
Link Transactions and Response Time metrics.
Read Requests Performance: This report table includes only the Split Transactions that present Read Requests (Configuration, IO and Memory). It groups them by the combination of Requester‐Completer pair, request type, and Traffic Class and displays
Minimum/Average/Maximum data for Throughput, Response Time, and Latency metrics.
Write Requests Performance: This report table includes only the Split Transactions that present Write Requests (Configuration and IO). It groups them by the combination of
Requester‐Completer pair, request type, and Traffic Class and displays Minimum/Average/
Maximum data for Throughput, Response Time, and Latency metrics (see the following figure).
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 243
Teledyne LeCroy Show Metrics in the Traffic Summary Window
10.17.2 Reports at the Link Transaction Level
The following metric‐based reports are displayed at the Link Transaction level:
Link Transaction Performance: This report table groups the Link Transactions by TLP Type and displays Minimum/Average/Maximum data for Number Of Packets, Response Time and Payload Bytes metrics.
Memory Writes: This report table includes only the Link Transactions that present
Memory Write Requests. Memory Writes are the only (posted) requests that don't get promoted to the Split transaction level, therefore their performance should be viewed at the Link transaction level. The table groups Memory Writes by the combination of
Requester ID and Traffic Class and displays Minimum/Average/Maximum data for
Response Time, Payload and Throughput metrics.
244
The following features apply to all of the report tables described above for the Split
Transaction and Link Transaction levels:
Each report row for the defined tables contains the total number of units in this group for the CATC Trace (total number of units for Split Transaction perfor‐ mance, Read Requests performance, Memory Writes, and so on).
In many cases, the Maximum and Minimum values in the report tables are navi‐ gable. By clicking table cells, you reposition the corresponding CATC Trace view to the Split or Link Transaction that has yielded this maximum or minimum value. This can help you to find specific units in the CATC Trace, such as transac‐ tions that produced spikes in Response Time or Throughput.

Show Metrics in the Bus Utilization Window Teledyne LeCroy
10.18 Show Metrics in the Bus Utilization Window
The Bus Utilization window provides graphs for packet‐level information in the
CATC Trace. The window also provides graphs for information on Split and Link
Transaction levels, plotted over time. The graphs for Split and Link Transaction levels are based on metrics collected for the transactions throughout the CATC Trace.
The seven graphs related to Split and Transaction levels are:
1. Pending Requests at Split Transaction level.
2. Response Time at Split Transaction level.
3. Latency Time at Split Transaction level.
4. Throughput Per Transaction at Split Transaction level.
5. Response Time and Latency Time at Split Transaction level (combined graph).
6. Response Time at Link Transaction level, for Memory Writes only.
7. Throughput at Link Transaction level, for Memory Writes only.
The following is an example of Bus Utilization window display of graph numbers 1, 4, 5, 6 and 7:
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 245
Teledyne LeCroy Show Metrics in the Bus Utilization Window
10.18.1 Unit-Based Averaging
The Analyzer builds metric graphs using unit‐based averaging (as opposed to time‐based averaging). For the total duration of a certain request (or Memory Write transaction), the graph value is assumed equal to the corresponding metric for this request (transaction). If there are overlapping operations for a certain time period, then the value is calculated as an average of metric values for all the overlapped requests (transactions).
It is important to remember that the Analyzer uses unit‐based averaging rather than time‐based averaging. Time‐based averaging can be misleading in some situations. For example, consider the Throughput Per Transaction graph. Sometimes, while many outstanding requests are in progress, latency (and response time) grows for each of the transactions, resulting in a lower throughput per transaction over time (which is reflected in the graph). This happens even though aggregated throughput across all the transactions is constant.
10.18.2 Bus Utilization Window Features
For the seven Split‐ and Transaction‐level graphs listed, all Bus Utilization window features are available, such as zooming in/out, changing scale type, scrolling, context‐ sensitive status, and graph synchronization. See Bus Utilization and Bus Utilization
Buttons for more on these features.
Note:
Clicking a certain place within a graph area repositions the CATC Trace display at the Link or Split transaction level to the transaction that was in progress at that time.
10.18.3 Split Transaction Level Graphs
Transactions at the Split level combine all the non‐posted requests with corresponding completions. This includes Configuration and IO Read and Write requests, as well as
Memory Read requests.
The following figure shows the graphs for the Split level:
246 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Show Metrics in the Bus Utilization Window Teledyne LeCroy
Note:
The Pending Requests graph is not directly defined by metrics, but it is useful when considering metrics. The Pending Requests graph presents the unit‐averaged number of requests that were pending (in progress) at any moment of time. It allows you to correlate the number of requests posted to a completer with other performance metrics.
10.18.4 Link Transaction Level Graphs
Memory Writes are the only (posted) requests that do not get promoted to the Split transaction level. Therefore, Memory Write performance should be viewed at the Link
Transaction level. That is the reason graphs at the Link level only present the Memory
Write‐related metrics and are titled Writes: Response Time: and Writes: Throughput (see the following figure).

PCIe SSD Base Address Mapping Teledyne LeCroy
10.23 PCIe SSD Base Address Mapping
In order for NVMe, PQI, AHCI, ATA, SOP and SCSI decoding to work correctly, the PCIe
Protocol Suite software needs to know the Memory Base Address of the device. In cases when Base Address assignment is recorded in the trace, the software will determine all the values automatically. If the Base Address assignment is not present in the trace, you can specify the values manually using this dialog. You need to select the type of the device (NVMe, PQI, AHCI, ATA, SOP or SCSI) and set the value of the Base Address by selecting Tools > PCIe SSD Base Address Mapping. The PCIe SSD Configuration dialog displays (see Figure 10.39 on page 264 ).
Note:
From software release 6.63 onwards, users are able to decode NVMe/PQI traces which are lacking configuration space and administration information, from release 6.70 this is applicable to AHCI traces, from release 7.00 this is applicable to ATA traces and from release 7.10 this is applicable to SOP and SCSI traces.
Note:
From software release 7.30 onwards, multiple NVMe devices can be decoded from the same trace.
Note:
From software release 7.34 onwards, the SSD Dialog displays the Device Name as read in the configuration accesses.
Follow the steps below to perform the applicable storage decoding:
1. Record the trace for NVMe, PQI, AHCI, ATA, SOP or SCSI device boot and decode it.
This saves the configuration space and administration information in .xml format, which is used to decode traces that do not include configuration and administration commands.
2. Record the trace of the same NVMe, PQI, AHCI, ATA SOP or SCSI device without rebooting and the application will decode it.
You can keep recording and decoding until rebooting. On reboot repeat steps 1 and 2 above.
10.23.1
NVMe PCIe SSD Device Configuration
The PCIe SSD Configuration dialog is used to add missing information to decode the trace without the configuration space and queue administration information. See Figure 10.39 on page 264 for NVMe PCIe SSD Device Configuration.
Prior to decoding, if all the required information is available in Configuration Space then the Source field in the PCIe SSD Configuration will be set to "Config Space" (see
Figure 10.39 on page 264 ). The description for important fields and buttons are given below:
1. DEVICE ID: Represents the device ID in the bus/device/function address from the

7. ACQS: Defines the size of the Admin Completion Queue in entries. Refer to the controller registers section of the NVMe specification. The minimum size of the
Admin Completion Queue is two entries. The maximum size of the Admin
Completion Queue is 4096 entries. This is a 0’s based value.
8. DSTRD: This register indicates the stride between doorbell registers. The stride is specified in bytes. This may be used to separate doorbells by a number of bytes in memory space. It may be useful in software emulation of an NVMe Express controller. For hardware implementations of NVMe Express, the expected doorbell stride value is 4.
9. LBASIZE: Size for Logical Block Addressing.
10. MPS: This field indicates the host memory page in bytes.
11. IOCQES: I/O Completion Queue Entry Size. This field defines the I/O Completion
Queue entry size that is used for the selected I/O Command Set. The required and maximum values for this field are specified in the Identify Controller data structure for each I/O Command Set. The value is in bytes and is specified as a power of two
(2^n).
12. IOSQES: I/O Submission Queue Entry Size. This field defines the I/O Submission
Queue entry size that is used for the selected I/O Command Set. The required and maximum values for this field are specified in the Identify Controller data structure for each I/O Command Set. The value is in bytes and is specified as a power of two
(2^n).
13. MQES: Maximum Queue Entries Supported. Defines the maximum individual queue size that the controller supports. This is a 0’s based value. The minimum value is 1h, indicating two entries.

).
Note:
When opening a trace file created with 7.0X or older versions of PCIe Protocol Suite, these new fields are not present and the application tries to export the configuration information to XML before decoding NVMe transaction level. In this case a message box will show claiming that a value for this field is required.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 265
Teledyne LeCroy PCIe SSD Base Address Mapping
Note:
In case of problems when opening older traces try the following: a) Decode NVMe transaction level before exporting XML file. This will apply the default value for the new fields and export can be performed. b) Manually enter the values for the new fields. c) In case the trace contains submission entries which are not decoded, add a new Queue and set the corresponding address in the PCIe SSD Configuration dialog.
10.23.2 AHCI PCIe SSD Device Configuration
The PCIe SSD Configuration dialog is used to add missing information to decode the trace
without the configuration space and queue administration information. See Figure 10.41
for AHCI PCIe SSD Device Configuration.

Appendix A
Configuration Space Decoding
The decoded capability structures in the Configuration Space Viewer and Editor are based on programmed definitions in the PCIe Protocol Suite software and on Configuration
Space Decode Scripts.
Configuration Space Decode Scripts are tools to define capability structures and instruct the Configuration Space Viewer or Editor how to decode them. These scripts are in the
\CfgSpaceScripts sub‐directory below the \Scripts directory in the application directory.
You can write Configuration Space Decode Scripts using the CATC Scripting Language (CSL).
See the Teledyne LeCroy Analyzers File Based Decoding Manual for reference.
PCI Express Configuration Space Decode Scripts have the file extension .pecfgdec.
Configuration Space Decode Scripts must set the following reserved variables.
CapabilityName: Name of the capability structure
CapabilityID: ID of the capability structure
ExtAddSpace: Set to 1 if Extended Configuration Space. Else, set to 0 for PCI.
Modules are collections of functions and data dedicated to decoding a specific capability structure. Each module has one primary Configuration Space Decode Script file
(extension .pecfgdec) and optionally has include files (.inc).
A module function is an entry‐point into a decoding module. To help display a capability structure, the application calls a module function.
The Configuration Space Editor and Viewer support only the DecodeRegister(offset) and
GetSize( ) functions.
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 287
Teledyne LeCroy Configuration Register Types
12.2.1 DecodeRegister()
DecodeRegister(offset)
The application calls this function while decoding a specific DWORD offset of the specified CapabilityID. The offset is the decoding entry point, where the decoding path starts.
The Configuration Space Editor calls this function to determine how to decode the assigned configuration space. The offset parameter is the DWORD to decode.
An offset of 0 indicates bytes 00h‐03h, an offset of 1 indicates bytes 04h‐07h, and so on.
Note:
The Configuration Space Editor can only decode one DWORD at a time.
12.2.2 GetSize()
This function returns the size of the capability structure specified by CapabilityID.
288
The following reserved variables are defined global constants.
CFGREG_UNDEFINED
CFGREG_HWINIT
CFGREG_RO
CFGREG_RW
CFGREG_RW1C
CFGREG_ROS
CFGREG_RWS
CFGREG_RW1CS
CFGREG_RSVDP
CFGREG_RSVDZ
Note:
These reserved variables match the Configuration Register Types of Table 7‐2 in Section 7.4 of the PCI Express Base Specification, Rev. 2.1.
12.4 Primitives
Decoding uses the following primitives.
12.4.1 GetRegisterField()
GetRegisterField(dword_offset, bit_offset, field_length)
This function returns a register field of length field_length, starting at bit position
bit_offset in DWORD dword_offset.
dword_offset: DWORD offset of the register field location
bit_offset: Bit offset of the register field location
field_length: Length of the register field
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Primitives Teledyne LeCroy
For example, GetRegisterField(1, 9, 2); means: Go to DWORD 1, bit offset 9, and returns 2 bits.
12.4.2 AddField()
AddField(field_name, field_length, configuration_reg_type, tooltip, encoding_table =
NULL)
This function adds a register field to the Capability View and returns a pointer to the field, for adding subfields.
field_name: Name of the register field to display in the Capability View
field_length: Length of the register field
configuration_reg_type: Configuration register type of the register field.
Note: If subfields are defined, their configuration register types override this set‐ ting for their specified bits.
tooltip: Tooltip displayed for the register field in the Capability View
encoding_table: Optional. Displays encodings as lists for select values.
For example, user input becomes a combo box for the field in the Field View.
As examples:
AddField("PCI Express Extended Capability ID", 16, CFGREG_RO, "");
means: Add the field “PCI Express Extended Capability ID” with length 16 and cfg register type CFGREG_RO.
capability_reg = AddField("Capability Register", 32, CFGREG_RW, ""); means: Added the field “Capability Register” with length 32 and cfg register type
CFGREG_RW and stored a pointer to this field in variable capability_reg, which can be used to add subfields to this field.
12.4.3 AddSubField()
AddSubField(parent_field, subfield_name, subfield_length, configuration_reg_type, tooltip, encoding_table = NULL);
This function adds a subfield to a register field in the Capability View. Subfields are modifiable and visible in the Field View and appear in the tooltips of register fields.
parent_field: Pointer to a register field in the Capability View
subfield_name: Name of the subfield, displayed in the Field View
subfield_length: Length of the subfield
configuration_reg_type: Configuration register type of the subfield field.
Note: This overrides the configuration_reg_type of the parent field.
tooltip: Tooltip displayed for the subfield in the Capability View
encoding_table: Optional. Displays encodings as lists for select values.
For example, user input becomes a combo box for the field in the Field View.
For example,
AddSubField(capability_reg, "Mode Supported", 4, CFGREG_RO, "Indicates the
Function modes," ), ModeEncodings);
means: Add the subfield “Mode Supported” to the parent field “capability_reg” with
Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual 289
Teledyne LeCroy Helper File length 4, type CFGREG_RO, a tooltip in the Capability View, and a combo box displaying
“mode encodings” for input in the Field View.
ConfigSpaceCommon.inc include file contains useful functions for script decoding.
