Hi,

Yes I already simulated the FFT function under ModelSim, it worked well with the version 13.0.

If I remember well, you only need the fft.vo file in ModelSim, not the fft.v (I don't know what is your fft_bb.v).

Then, one thing that is often forgotten, is that you need to have the 6 cos/sin.hex files generated by the MegaWizard in the same folder as your fft.vo file.

Once you are sure of these two points, if you still have trouble, I think that ModelSim should give you some warnings. Could you indicate what are they ? Could you also put a screenshot of the wave in ModelSim ?
