Chapter 13, Configuring Xgig TraceView Filter And Hide
286 Xgig Analyzer User’s Guide
The graphical state machine has four states, and it corresponds to the state machine displayed in
the FC_Port state machine section of the FC-FS-3 specification. However, the speed negotiation
state has been renamed to 16G training speed neg. because the Xgig analyzer does not detect the
speed negotiation phase, but it captures the training frames in that phase, and that is what is shown
in the state machine.
The graphical state machine highlights the path taken in the training sequence with a mixture of
green, yellow and red lines. The green line shows a successful path. The red line shows an error
path. The yellow line shows a successful path with some warnings.
To view the details of any state or any state transition, click inside the state box or the state
transition text, and the
Selection Details section is automatically populated with the details.
All the counters, symptoms, warnings, and errors are displayed in the
Selection Details
section.
The errors causing the state transition are displayed in red. Warnings are displayed in orange, but
they do not cause a state transition.
The details for the transmitter training state also contain the Training_Sequencer sub-states for
both ports in the port pair ordered by timestamp.
Following are the context menus available in the Selection Details section:
•
Copy All
: Copy the entire
Selection Details
section to the clipboard so it is possible to paste
the content to a text editor.
•
Go to occurence...
: This context menu is available on lines where a count (Cnt) is shown for
a counter. It opens a dialog where you can select a number in the range (1-Count). Then, the
main TraceView grid highlights that occurrence of the event, and you can navigate in the main
grid in parallel to this dialog.
•
Description
: Opens a tooltip with a full description of that event.
When you click a hyperlink in the Selection Details section, the main TraceView grid highlights
the event corresponding to that timestamp. You can navigate in the main grid in parallel to this
dialog. You can also right-click any event in the main grid and select the context menu
Show in
Graphical Transmitter Training
, and the dialog will highlight the state containing that event.
When you right-click any error transition text in the graphical state machine, and select Show in
main grid
, that menu will highlight the event that caused the error transition in the main grid.
PCIe Device and Address Mappings
The PCIe Analyzer remembers the devices and address mappings from a prior boot-up sequence in
order to analyze and decode future traces. You can manually enter the all devices and addresses in
the
Devices And Addresses
dialog. Expert automatically generates those mappings when it
processes a boot-up sequence. To open the dialog, click the Devices And Addresses button in
TraceView’s toolbar, or select
Devices and Addresses...
from the
Edit
menu. This button is
enabled when you open a trace file or capture buffer.
The
Devices And Addresses
dialog has either one or two tabs. The first tab shows the mapping
stored in the pre-capture.devices file. If present, the second tab shows the mapping in the
post-capture.devices file.
