Hi,In my project, I have to implement the FFT and IFFT operators. I have seen megafunction FFT integrated in Quartus II, but I don't know where's the IFFT core. Please show me where's IFFT core. Is the IFFT and the FFT core are the same? Thanks,

The IFFT can be implemented with an FFT. IIRC you need to do a conjugate operation on both the input and the output, and you may need to do a scaling (divide by N I think).
