40 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Example
If you create a 1010 MB recording using 10 MB segments, the following files and sub‐
directories are created:
data.pem (This is the index file.)
data_pem_files\00000\segment_00000.pex
data_pem_files\00000\segment_00001.pex
...
data_pem_files\00000\segment_00099.pex
data_pem_files\00001\segment_00100.pex
data_pem_files\00001\segment_00101.pex
Note: An additional index file is created called segments.col. This is an internal system file
that users should not modify.
4.12 PETracer Files
The PETracer 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
4.12.1 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
<filename>.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.
4.12.2 Recording Options Files
Recording Options files are created when you set recording options. These files use the
.rec extension and contain recording option information.
