Hey Andrew. Thank you for your reply.
The PFB and FFT size that I am using is 1024 channels. I can run the tutorials without any problems. I have removed the PBF_real bock and I get the following error: Simulink:Masking:Bad_Init_Commands: Error in 'rfsoc_zsu111_narrowband_v5/fft_wideband_real1/fft_biplex_real_4x/bi_real_unscr_4x/hilbert0/add_even_real/a_debus': Failed to evaluate mask initialization commands. It is weird because it is the same block as in the tutorials. The board I am targeting is the RFSoC ZCU111 and the RFSoC 4x2. Am I mussing something stupid? Thank you for the help.

Large PFBs can take many minutes to initialise. How long are you waiting before you give up? Your error could come from a number of sources. You need to simplify things in an effort to isolate the problem. Some things to try: - Check that you have the correct version of toolflow, mlib_devel etc. have you run any tutorials successfully with your setup? - Simulate the PFB in a separate, very basic design starting with just the FFT block and a very small number of channels. Keep an eye on the messages emitted to look for errors and warnings that might give you clues... - If that works, simulate your design with just the FFT (again starting with a small number of channels). Check that you can simulate, even if the resulting data is rubbish. Again, look for clues in messages. - If that works, add the pfb_fir_real to your design but keep the number of channels etc very small. Good luck and regards Andrew On Mon, Jan 20, 2025 at 1:47 PM Heystek Grobler <heystekgrob...@gmail.com<mailto:heystekgrob...@gmail.com>> wrote: Good day everyone. I hope that you are doing well. I have a weird situation where Simulink get stuck while initialising the simulation. The design is a narrowband spectrometer. I played around with Simulink, and the simulation won’t initialise as soon as I add a pfb_fir_real block and a fft_wideband_real block. If I comment out the blocks, then the simulation initialises and runs. Has anyone stumbled across something like this? Thank you for the help.
