Critical Issue
Description
The PCI Express Base Specification states that receivers can optionally check the Address Translation (AT) bits of the Transaction Layer Packet (TLP) and flag the received TLP as malformed if AT is not 2’b00. The Stratix V Hard IP for PCI Express does not perform this check.
Resolution
No workaround is required; however, you cannot rely on the AT bits to flag malformed TLPs.
