Altera FFT Vs Matlab FFT. Strange Results

Hi, I’m testing some FFT Altera Core using those parameters: 1)Single Streaming or Burst 16K length FFT 2)12-14-16 bits input REAL data (pseudorandom code {-1,1}) 3)same bits for twiddle...

Hi,

It seems that I am having the same issue.

My fft_sink_ready signal (called out_sink_ready) is being set to 0 after being asserted to 1 a couple of cycles before. I do not know why this is happening. Any help with this matter will be greatly appreciated.

Furthermore, since I am aware of the scaling issue in the streaming implementation, I ensured that the real input is FFFF (16 bits) - the largest number possible.

Thank you!
