Hi, Sebastian, If you're only changing the inputs (i.e. NOT changing parameters of the CASPER blocks), you might want to consider building a test design that allows you to provide the inputs via a "Shared BRAM" block and reading the output from another "Shared BRAM" block. Then you could "simulate" in hardware (assuming you have hardware...), which will be very much faster.
If you're changing the parameters of the CASPER blocks, then perhaps testing with a smaller PFB/FFT would speed things up while you hone in on the parameters you want to explore in more depth. Then you can try a smaller set of tests on the larger PFB/FFT.
