I downloaded the project "CF_FFT"
and write a testbench that make the signal "enable_i" high,
sync_i pulse before data input,
but the sync_o always didnt pulse,so i cant get the outdata
All i get is data_0_o = "0" and data_1_o = "X"
Do anyone know what's wrong?

and more question is that

cf_fft_2048_18.v has input "data_0_i" and "data_1_i"
for a 2048-point data , just input to the two signals in 1024 cycles,
1024 data each, is that so?
thanks!

I am facing this trouble as well
