... vhdl generic: I m new to vhdl, and I tried to use xilinx fft core, but when I try to simulate it in test bench using ise ... zero results.
here is what I do:
1- from core generator I choose fft core and create .vhd & .vho & .xco files.
2- I add the .xco ...

FFTGUI Demonstration of Finite Fourier Transform.
FFTGUI(y) plots real(y), imag(y), real(fft(y)) and imag(fft(y)).
FFTGUI, without any arguments, uses y = zeros(1,32).
When any point is moved with the mouse, the other plots respond.
