OFDM Megacore

Hi,

I am trying to use the ofdm modulation/demodulation megacore. As per User Manual, I have to add the fft library to the user library, which I have completed. This is from user manual :

option 1: in the quartus ii software, add

\ofdm_modulation\source\fft72 to the user library. then

re-generate the fft megacore based on the wrapper provided in

\source\fft72\. doing this ensures all the necessary fft library files

are included.

However, I have problem in the second step to re-generate the FFT megacore based on the wrapper provided. I am quite new in this area, and I am not very sure what does it mean. Anyone can help me?
