11.4 EDK, MPMC v5.04.a, Spartan-6 ES Silicon - MCB memory access failure patch

Description

When using CES Spartan-6 devices, the MPMC memory access is unreliable. How do I resolve this issue?

Solution

This issue is related to the MIG (Xilinx Answer 34089).

Extract the following zip archive to the project pcore/ directory.

This issue does not affect production devices, and this pcore should likely be removed when targeting production silicon. This patch targets 11.4, 11.5, and 12.1 versions of MPMC. The same changes will need to be made to all future MPMC designs when using ES devices only.
