Clocking Wizard v3.3,the Defense Grade Virtex-6Q Lower Power devices are not supported. For more information, see (Xilinx Answer 42530).
Known Issues
In v3.5 of the Clocking Wizard, if you select a BUFHCE as the output buffer the example design might be unroutable with the default constraints. The BUFHCE can drive a single clock region.
In the Clocking Wizard v3.5, example design implementation with the BUFHCE as the output buffer might fail due to the placement of logic in multiple clock regions. To work around the issue,you can provide constraints to lock the output clock pin and the BUFHCE into the same bank.
