12.1 Project Navigator - Double-clicking on IP core results in "ERROR:sim:623 - Unable to create new project..."


When I double-click on the XCO file to open the respective IP Core customization GUI from Project Navigator,the customization GUI fails to open and the following error occurs:

"ERROR:sim:623 - Unable to create new project < Project_directory >\ipcore_dir\coregen.cgc'. Project file already exists. ERROR:encore:268 - Project< Project_directory >\ipcore_dir\coregen.cgc could not be opened."


When the customization GUI is called, the CORE Generator software is attempting to create a new coregen.cgc (12.1 CORE Generator project) file instead of using the existing file.

Possible work-arounds to this error are as follows:
  • Delete the "coregen.cgc" file from the project.
  • Regenerate the core in the processes window.After regeneration, the customization GUI can be openedby double-clicking in Project Navigator. NOTE:After regenerating the Core, ifa "Cleanup Project Files" operation is performed, thenthe issue returns.

This issue has been resolved in ISE Design Suite 12.2.
