FFT_verification

Hi ! When I run FFT and IFFT tool in megawizard, the results are not logical. For example firstly I run the FFT tool with the megawizard tb (input: natural order, output : digit reversed order)...

Have you tried checking what the input file looks like when you generate a testbench for the IFFT, there's no guarantee the output file of the FFT matches the input format for the IFFT.
