If I import an XCO file using Project -> Import Existing Customized IP, the following error occurs:
"FATAL_ERROR:GuiUtilities:Gui_Clip_ApplicationBase.c:369:1.30 - No index entry for element ID '' found 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
This error occurs when the current project has a device set that is incompatible with the imported XCO.
To work around this error, copy the XCO and associated files to the project directory of the current CORE Generator project. When the CORE Generator tool opens, it reads all of the XCO core files into the project directory. At this point, the core can be regenerated with the "Current Project Settings" if desired.
This issue has been resolved in ISE Design Suite 14.3.
