LogiCORE Fast Fourier Transform (FFT) FFT compiler 7.1

Hi all!

I have some troubles when I use ISE 14.7 during the simulation of the LogiCORE FFT v7.1. My target board is Virtex-6 ML605 and I use floating-point data whice meet the IEEE 754 standard. However, the result is different from MATLAB fft. Even when I use ifft(set fwd_inv=0 & fwd_inv_we=1), the result is different from the initial data.

Any suggestion is very appreciated.

Thank you.
