LogiCORE IP Tri-Mode Ethernet MAC v5.4 and earlier - Multiple pause frame requests can result in a corrupted pause quanta being output


When using the Tri-Mode Ethernet MAC v5.4 and earlier, it is possible for the pause quanta in a transmitted pause frame to become corrupted when requesting back to back pause frames. 

The upper 8 bits of previous pause value and lower 8 bits of the current pause value can incorrectly be sent together for the pause quanta in the same transmitted pause frame.


This issue has been resolved in the Tri-Mode Ethernet MAC v5.5 core.

If using the v5.1, v5.2, v5.3 or v5.4 cores, the SHIM in the below file can be used with the core. 

See the readme file contained in for information on how to instantiate and connect the SHIM.

If using the v4.6 Tri-Mode Ethernet MAC core, see (Xilinx Answer 53139)
