10.1 ISE/EDK - ERROR:MapLib:978 - "<block_name> has an equation that uses input pin ..." when using EDK subproject in ProjNav

Description


If running an EDK subsystem in ProjNav, and you make changes to the hardware, you could get errors such as:



ERROR:MapLib:979 - LUT6 symbol

will be trimmed. See Section 5 of the Map Report File for details about why
the input signal will become undriven.

Solution


Notice that the errors are on a plb_v46 instance. There will likely be many such errors.



This can happen from a stale NGC in the ProjNav project directory. The fix is to manually clean all NGC files in the Project Navigator folder that come from the EDK submodule, then re-implementing.
