The Virtex-6 FPGA Integrated Block Wrapper v1.4 rev 2 for PCI Express was released as part of the ISE 11.5 update. For more information on ISE 11.5, see (Xilinx Answer 34571). The Virtex-6 FPGA Integrated Block Wrapper was updated in 11.5 to fix the issue discussed in (Xilinx Answer 34144). Users who generate the core in 11.5 will receive v1.4 rev2 and do not need to worry about the issue with the MMCM VCO settings discussed in (Xilinx Answer 34144).
However, users who update to ISE 11.5 and want to use VHDL should download the v1.4 rev 3 patch. This patch enables VHDL generation of the user example design and the simulation testbench.
Please see (Xilinx Answer 34279) to download this patch.
