FFT MegaCore Function simulation in Modelsim never finished

Hi, everyone! I'd like to ask those who deals with FFT MegaCore Function. My problem: I can't get generated FFT MegaCore Function simulation finished in Modelsim. I create a project in...

Hi, Jérôme!

Thanks for reply.

As I see in fft_tb.v file and in the Wave window of ModelSim all inputs of FFT function instanse are connected and have definite values (St0, St1), while all the outputs (including source_error) signals are in HiZ state whenever I stop simulation. Anyway, I rely on this generated testbench file, which seems to be quite consistent.

By the way, megafunction wizard generates MATLAB model, and it works fine.

Did you ever try simulate this megafunction in ModelSim yourself? May be there is bug in FFT v13.0?
