FFT Mega Core IP

I am working on FFT MegaCore IP. I would like to give 64 points to the generated file and get the output using Altera DE2 board not the simulation. I built a top level file.v to pass the inputs...

i am still not quite sure what you are doing, maybe posting a block diagram would help? how will you verify the output data from the FFT?

sounds like you are feeding the FFT 64 samples from a lookup table, hopefully into the sink_real and sink_imag inputs of the FFT? you could try using SignalTap on the source_real and source_imag outputs of the FFT.

other than that have you verified functionality in simulation? the Avalon Streaming signals can take a little bit of work to get right.
