When I use Ctrl-V to paste values into the Frequency column, XPower crashes with an error dialog box similar to the following:
"FATAL_ERROR:GUIDUtilities:WinApp.c:657$Revision - This application has discovered an exceptional condition from which it cannot recover. Process will terminate. To resolve this error, please consult the answer database and other online resources located at www.support.xilinx.com. If you need further assistance, please open a Webcase by clicking on the "Webcase" link at www.support.xilinx.com."
To work around this issue, perform the following:
1. Expand the desired folder by pressing the '+' button.
2. Press Ctrl and click to select each signal name to which you want to assign the same frequency.
3. Right-click and select "Set Frequency of Asynchronous Nets."
4. Enter the appropriate value.
