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)...

If change the "I/O Output Order" of FFT and "I/O input order" of IFFT to "digital reverse Order", then the input of FFT should be equal to output of iFFT. I'm able to get the correct result.
