Unable to get correct output in my FFT megacore function model

My inputs are fed correctly but my FFT megacore output always shows a 0 

 

O/P signals 

sink_ready=1 

sink_valid=1 

 

Streaming Mode FFT 

 

Is anything wrong in my Simulink model 

 

I have attached the .mdl file
FFT_altera.zip

Without having looked at your code I can only say that you need to obey to the protocol for the Avalon ports: sink_sop, sink_eop and reset for the FFT to work. Also - you must have source_ready=1 to enable downstream flow. Good luck
