ISE Design Suite 11.4.1 - Known Issues for Virtex-6 FPGA Service Pack

Description

ISE Design Suite 11.4.1 is alimited release thatis for customers who have received Production6VLX240T silicon only. If you have further questions, please contactTechnical Support. Critical: You must rerun your design through the implementation tools after installing ISE Design Suite 11.4.1.

Certain IP products may error during implementation due to new requirements on the Virtex-6 FPGA MMCM attribute settings. See Xilinx Answer 33849 which is also listed below for more information.

Please note that the 6VLX240T speeds filesincluded in this update have been verified against production silicon and are now labeled "PRODUCTION." However, full hardware validationof IP coresis NOT available for ISE Design Tools 11.4.1. If you experience issues with IP Cores, please reference theKnown Issues section of this Answer Record.Bug fixes for most issueswill be in a future ISE Design Suite update(currently scheduled for March2010).
