FFT IP not working

Dear All, I did some projects using FFT IP to process 20Khz signal from two-channel 5MSPS simultaneously ADC. however, the FFT IP from my design is not working properly. The source_imag of FFT Ip i...

Hi CheePin,

yeah, still stuck to the last problem, I can't get a signal that represents real and imaginer. I think the sampling data needs some pre-processing or signal conditioning before wiring to FFT IP. btw I did a simulation using Matlab Simulink and the output is good as expected. well, I need to learn more about this FFT IP.
