cf FFT

[Marco]

My name is Marco and I'm working on my final year project, one subblock of
my project is a fft.
I would like to develope it myself (the fft) , but their is no time for that
because i have only 12 weeks for the hole project.
I got the cf_fft 512(vhdl version) on opencores.org but i have problems with
it,
the only thing that i get on the output_0_o is zero!
Is their a special pattern that i have to plug in at the three control
inputs
(enable_i,reset_i,sync_i<= i tested all 8 pattern) or do i need a special
clock ???

It would be very nice of you to give me a short introduction what i have
to do to bring the fft to run.

Greetings Marco

As far as I know, the Xilinx Coregen tool has a FFT module and should
be fairly customisable. Theres generally pretty good documentation
with them aswell. Definately worth a look!
Hope this helps
