How to use FFT megacore version 14.0 as IFFT

Honored Contributor II

Hi Guys, 

I am trying to simulate the FFT megacore version 14.0 of altera as IFFT. My question is that can i just use FFT core as IFFT by setting the inverse signal to high or i need to divide the output by N as well. I would also like to know that which ports are optional in FFT megacore of altera. 


Thank you for support
