Hi every body:
after alot of work i successed to add FFT core to my Project
and I attached some picture about how to add FFT
1-First you should add FFT core from Megafunction (as attached file1)..
2-add your Wrapper FFT to the Project path (file: fft_avalon_wraper.v). and you should change it to match your project.
3-add your FFT core as (new component) to SOPC builder (as attached file2-3-4).
4-connect your FFT to SGDMA (as attached file5-6-7).
5-be cerful to the Arbitration number (as attached file5).
6-add your code in C project (as attached file8).
i hope that will successed,
good lock all.
