Re: FFT_tb

Altera_Forum · ‎01-26-2015

Hi !

I created 16 FFT code by using megawizard. I ran its stimulation by using the test bench code which megawizard created.

It is running only for 4 frames. I modified the frame number and its source files( sink_real.txt and sink_imag.txt) but I couldnt run it for more frames.

I want to run it for 16 frames. Did anyone try this ? Is it possible ?

thanks

If you're using fft_tb.v then you need to edit line 51:

parameter NUM_FRAMES_c = 4;

To what you want.

For fft_tb.vhd you need to edit line 56:

constant NUM_FRAMES_c : natural := 4;

Does that help?

I am using VHDL .I have editted the line 56 I didnt work.

I figured out the problem .

We have to edit also line 59.

signal fftpts_array : fftpts_list_t := (16, 16, 16, 16);

this array legnt must be the same with the frame number..

Thanks a lot
