Digital Signal Processing - IP and Algorithms

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.
