I have a System Generator model, which uses a black box to incorporate a top-level VHDL file. I keep getting errors similar to below:

When exporting from System Generator as a PCORE,so long asthe _config.m file is set up correctly thePCORE directory structure should becorrect and all the files should be there.

In the _config.m, specify the .ngc filesfor the cores that are inthe blackbox portion of the design. The syntax for this is:

this_block.addFile('corename.ngc');

Add this type of line for every file that is referenced by the blackboxtop level.This is similar to a compile order for a BBD file and System Generator will annotate the BBD file correctly.
