Virtex-6 FPGA Integrated Block Wrapper for PCI Express - The v1.3 and v1.3 rev 1 Core is not linking up reliably on ES (engineering sample) silicon using ISE 12.1 and ISE 11.5 or later software


Due to the automatic insertion of the MMCM calibration block that occurs in ISE11.5 and ISE 12.1 tools, the v1.3 or v1.3 rev 1 core might notreliably link up. This could occur on the ML605 board as well as your own board.


This issue is fixed in the v1.3 rev 2 patch. Refer to (Xilinx Answer 34279) for the patch.
