Description
Keywords: clock, uncertainty, hold, time, global, BUFGMUX, BUFG
When I do timing analysis on my design, I receive a hold violation on a global or BUFG clock. The Clock Uncertainty value is non-zero and results in the hold violation. A hold analysis on a global clock should not include clock uncertainty. When will this be fixed?
Solution
This problem has been fixed in the latest 8.1i Service Pack available at:http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 8.1i Service Pack 3.
