Hi Daniel Sorry for the nasty surprise after all the hard work.
The good news is that I have very recently (Monday) compiled a design using those library blocks and do not notice the problems you have. There are a few things to do to figure out what the problem is; 1. Check that the block parameters (FFT size, bit widths etc) were copied correctly when replacing the old blocks with the new. 2. Simulate the old and new designs and compare the outputs. Putting a scope on the output of the fft block in this case should give you a good idea of what is happening. This will require a bit of work but simulation is a key skill to learn. 3. If these steps don't help figure out the problem, send me the design with the new pfb_fir and fft_wideband_real blocks, as well as the git commit hash for the version of the libraries you are using (use git log). Regards Andrew
