I upgraded to SP2 Quatus 9.1 / Modelsim ASE 9.5b, and the hex memory files stopped working. However, after copying the mif file into the simulation modelsim directory the mif file works and my hex files dont. I didn't spend to much time debug why the hex failed since I perfer the mif file format, but it was strange event.

Is there something I need to do to get modelsim to load the mif file from the source directory instead of looking at the local current simulation directory?
