Thanks. Yes, I just re-read the NCO user guide and I can simulate the my NCO design vhdl file on ModelSim now. I used automatically generated tcl file to run the simulation. The instructions to follow is in page A-2 of the NCO MegaCore function User Guides.

Great! Glad to hear you got it working.

I think Altera should remind users that the testbench file should not be used in Quartus but will be used by the tcl file to run simulation in Modelsim. In Xilinx, you can run the testbench file directly (recall from my memory).

I think Altera relies on the error messages to remind you :)

Cheers,
