Virtex-6 FPGA - Known Issues for the Virtex-6 CXT FPGA device


The Virtex-6 CXT FPGA device is supported in ISE Design Suite 11.2 and later software, but IP and third-party software support is limited.


ISE Design Suite 11.2 and later software support allows users to target Virtex-6 CXT FPGA devices. 
At this time, there is limited IP support and third-party synthesis tool support for these devices. 
For details on which IP are supported for the latest release of ISE Design Suite, see the IP Release Notes Guide at: 
The Synplify Pro Synthesis Production version C-2009.06 does support CXT devices. 
In some cases, Virtex-6 CXT device support is required for an unsupported synthesis tool or IP. As a work-around, you can target similar Virtex-6 LXT devices in the synthesis tool and the CORE Generator tool first, then re-target to CXT devices during design simulation, implementation, and while using the Power Estimator/Analyzer. The UCF constraints file should also be modified for the CXT device.
