Simulation MegaCore FFT in ModelSim - Problem!

Hi All,

I'm currently trying to simulate a FFT using the Testbench generated by the MegaWizard Plugin Manager. I've compiled fft.v, fft_bb.v and fft_tb.v to the library (with fft as the variation name) and am running the simulation from the fft_tb module.

When running the Simulation, it doesn't work! And I think that's because the FFT sub-module isn't being instantiated. When looking on the files tab of the fft_tb simulation, only fft_tb.v and fft_bb.v are there, I think fft.v should be there as well, but I have no idea how to get it there?

Can someone point me in the right direction? Or am I going completely wrong somewhere?

Thanks

    _bb is a black box file and not necessary for simulation

    you need to make sure that the Generate Simulation Model checkbox is enabled when you generate the IP. then you want to use the _tb.v test bench and .vo simulation netlist to run your simulation
