16 years agoHave you installed the service pack for Modelsim 6.5b for Quartus II 9.1 that is shown on Altera's website? I seem to remember running into a similar port mismatch issue that was resolved when I installed the service pack for modelsim.
I can't say for sure that this is the exact issue, but it smells very similar to what I ran into...
