FFT MegaCore Function simulation in Modelsim never finished

Hi again, Jérôme!

If I follow your point and place in ModelSim project just one fft.vo file, simulation couldn't be started - ModelSim outputs '# error loading design' message. And it is clear - because fft.vo is just an 'IP Functional Simulation Model'.

To test module we obviously need:

1. IP Functional Simulation Model - fft.vo file;

2. Module interface declaration - fft.v file;

3. Testbench - fft_tb.v file;

4. BlackBox - fft_bb.v file (I don't know anything about it)

And to start simulation I need all of these 4 files, otherwise I get '# error loading design'.

So, that's what I have:

1. My project window

2. Simulation window (stopped after waiting long time)

Have any idea about it?
