This is a generic message that indicates that the generation of the core failed with an internal error in the elaboration phase.

This can be caused by a bad install, which is caused by installing over a previous incomplete uninstall. A particular situation where this has been seen is when customers install ISE 6.1i over ISE 5.2i. In this case, there is usually only a subset of cores that do not elaborate correctly.

Uninstall ISE from the Windows control panel.

IF THE INSTALL DIRECTORY IS NOT REMOVED IN THIS PROCESS, YOU MUST BE SURE TO DELETE IT MANUALLY.
This is probably what caused the problem in the first place.

Reinstall and apply the latest service pack.

This error message might occur on Windows operating systems with German or French regional settings. See (Xilinx Answer 19510) for details.
