I tried different timings for fwd_inv_we but none of them works (modelsim and ise simulator)
1. Before start
2. Rising start and fwd_inv_we at the same cycle (page 25 , data sheet)
3.
fft core v5.0 - ise 9.2i sp4
pipelined, streaming i/o
lenght 8
target clock 200MHz
unscaled
truncation
natural order
distributed ram
ce
Matlab
f = [ 8 0 0 0 0 0 0 0];
iF = ifft (f);
iF = [1 1 1 1 1 1 1 1];
F = fft (f);
F = [8 8 8 8 8 8 8 8];
Thanks in advance.
