I am new hand when using the FFT megacore 7.2. I learned the FFT core handbook for three days however I am not very specified about how to use the core.Especily about this paragram on using Buffered...

Source_ready: This signal indicates that the downstream module after FFT (at the source side) is ready to take more data.

Buffered burst data: Because how the core was implemented, you actually need to pass in more data (valid or not) into the FFT core, before you would get your last remaining packets out. Therefore, you do have to keep sink_valid high at the end (even when you don't have more real data).

Hope this helps.
