I understand the SDF FFT algorithms are cascaded how do I modify the code to realize smaller FFTs? I am running 32K FFT and wish to realize functions below that all the way down to 16.
Have anyone tried before?

Are you trying to reuse the code for variable length FFTs? If all you want is FFTs of different sizes, you can configure dsp.HDLIFFT with the appropriate FFT length and generate HDL code.

I have 32K FFT RTL working on my FPGA and wish to have 16K, 8K, .. etc by modifying the same RTL.
