12.4 Planahead - Synthesis Results in "EXCEPTION:Xdm:ModelImp.c:853:$Id: ..."


I see the following exception message at synthesis when running my project in the PlanAhead tool:

EXCEPTION:Xdm:ModelImp.c:853:$Id: ModelImp.c,v 1.28 2009/06/12 19:55:28 jdl Exp $ - Xdm_Exception::InvalidFileFormat format=binary file='<my_module>.ngc'

How do I fix this?


If the NGC files are added by pointing to a directory, the PlanAhead tool creates a directory structure that includes the NGC file name as a sub-directory. This can cause XST to give exception. This issue is fixed in PlanAhead 13.1.

It is recommended that you avoid naming directories with the extension .ucf, ncf, edf, or .ngc.

As a workaround, you can just point to ngcs rather than the directories.
