Description :
In the 6.2.3 Constraints Editor, there are signals incorrectly listed in the clock list. When is this going to be fixed?
To work around this issue, do not assign period constraints to these signals that should not be in the clock list.
This problem has been fixed in the latest 6.3i Service Pack available at:
http://support.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 6.3i Service Pack 2.
