The following fatal error has been found to occur while saving UCF files in ISE:
"FATAL_ERROR:GuiUtilities:Gui_Clip_AppliationBase.c:325:184.108.40.206 - This application has performed an illegal operation and must be shut down. Process will terminate. For technical support on this issue, please open a WebCase with this project attached at ..."
Restarting ISE results in the same fatal error when the project attempts to open.
The problems persists even after the machine has been restarted and the tools have been re-installed multiple times.
This fatal error can occur if the project database or .ise file have been corrupted.
To resolve the issue, delete the <project_name>_xdb folder and <project_name>.ise file. Upon opening the project using the .xise file, ISE will rebuild the .ise and database folder. The error should not persist.
If the solution above does not address the issue, please contact Xilinx Technical Support via Webcasefor further help.
