11.5 EDK, plbv46_pcie_v4_04_a - Potential block RAM collisions require EDK 12.1 for Spartan-6 production use

Description

When I use a plbv46_pcie_v4_04_a, block RAM collisions occur, causing data corruption or simulation collision warnings.

How do I resolve this issue?

Solution

General information on this collision issue can be found in (Xilinx Answer 34533).

A patch that partially solves this issue can be found in: http://www.xilinx.com/txpatches/pub/applications/misc/ar34712.zip.

To use this patch, extract it to the project pcore/ directory, restart XPS, clean hardware, and rebuild the project.

This issue is scheduled to be updated into PLBv46_V4_04_a in EDK 12.1 without a version change.
