Teledyne LeCroy Using Unit Metrics
192 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Figure 10.26: Configuration Space View
On the left, the view displays the Configuration Space for the selected CompleterID or
DeviceID at the current packet. You can select Configuration Space Header or a
Capability Structure.
The right displays the decoded data of the selected Configuration Space Header or a
Capability Structure, up to the current packet. (The decoding builds while navigating
through the next packets.)
The Configuration Space View toolbar allows you to S ave, go to First, go to Previous,
go to Next, go to Last, go to Previous Access to Selected Configuration Space Register,
go to Next Access to Selected Configuration Space Register, and display Hexadecimal or
Binary.
Note: See Appendix A “Configuration Space Decoding” on page 215 .
10.14 Using Unit Metrics
For every protocol unit at the Link or Split transaction level, PETracer™ 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.
PETracer defines different metrics for Link and Split transactions.
