Do I need to drive fftpts_in of the FFT Intel® FPGA IP core even if I'm not changing the block size?

Description

You may receive source errors (missing SOP, missing EOP) when attempting to process data through the FFT Intel® FPGA IP core when fftpts_in not being driven or being driven incorrectly.

Resolution

fftpts_in must be driven, even if one is not dynamically changing the block size. For a fixed block size implementation, it should be driven to match the transform length selected in the parameter editor.
