Virtex-7 FPGA Gen3 Integrated Block for PCI Express v3.0 (Rev3) - Extended Tag Field Support

Description

Version Found: v3.0 (Rev3)
Version Resolved and other Known Issues: See (Xilinx Answer 54645)

In the Virtex-7 FPGA Gen3 Integrated Block for PCI Express v3.0 (Rev3) core, when Extended Tag Field Support is set in the core configuration GUI, the core does not support 8-bit tag as defined in the spec.


Solution


This is a known limitation in the core. 

The core supports only 6-bit tag i.e. 64 tags in total. 

Note: "Version Found" refers to the version where the problem was first discovered. 

The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
