4.10 PETracer Files
The PETracer software creates and uses different kinds of files:
• Trace Files: Recorded traffic
• Recording Options Files: Configuration file that contains the various options
selected in the Recording Options dialog box to configure the recording
• Display Options Files: Configuration file that contains the options selected in the
Display Options dialog box to configure how traffic is displayed
CATC Trace Files
PETracer 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.
When Multisegment CATC Traces are created, a special index file is also created called
.pem. This index file provides a high level view of the CATC Trace segments
created in the recording session.
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.
Recording Options Files
Recording Options files are created when you set recording options. These files use the
.rec extension and contain recording option information.
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.
