FFT MegaCore Usage

Hi all,

I am working on a project including FFT transformation and I want to use the provided by Altera IP, but I am having some issues.

As I see in the ReadMe file (https://www.altera.com/content/dam/altera-www/global/en_us/others/support/examples/download/fft_32k_readme_v1_0_0.txt), I need to have FFT MegaCore v2.1.3 software on my PC, but I cannot seem to find out how to download it. Am I missing something out?

Can somebody please give me a hint on that? Your feedback will be very appreciated.

Thanks in advance!

    Hi bfkstimchan,

    You are right, there is an fft folder in my directory, but when I try to regenerate the FFT MegaCore files, I get an error saying that fft_small.v is not a valid MegaWizard-generated variation file. This is why I thought I was doing something wrong.

    Does anybody have any idea how I could deal with this issue?

    Hi bfkstimchan,

    I have same question.

    In my installation directory C:\altera_lite\15.1\ip\altera\fft\lib, there are lot of files named xxx_xxx_fft_151.v(vhd).

    Is the right place for "Specify the FFT MegaCore Function user library"?

    I have Quartus Prime Lite Edition 15.1. Is it can run the design example fft_32k?

    If not, Which vension of Quartus should be use?
