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

    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
