Xilinx cores are compliant with the Error Pollution section of PCI Express Base Specification. See section 6.2.3 for more information. This section explains that if a TLP contains multiple errors, only one is reported. For example, if the data link layer reports an error on a given TLP andif another error with the same TLP is found in the transaction layer, it will not be reported. See the specification for more details on how errors are classified and reported.
