Hi，are you still working with the FFT megacore? The same problem puzzled me now.I just created a fft ip core by Quartus II.But I don't know how to use it.

Do i need to wirte a state machine to control the sink_sop,sink_eop,sink_valid?

For example I want to analyse the signal sin(x) (0:1:1024) by FFT. I have got the 1024 pionts by matlab and saved the datas by file.

How to set up the input datas? 18bits and one by one or together?
