Hi All, I'm relatively new to FPGA programming, and as a part of a larger project, I am designing a FFT hardware solution to convert a live audio signal into frequency and amplitude pairs (but ...

...and that's as far as it gets.

I'm currently not getting any output from the instantiated FFT module, either as a wave form or in the file on disk.

Any ideas?
