6.13 Decoding Traffic
The PETracer 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.
