Hi Tilak, The issue you describe, where system generator hangs indefinitely, is a known issue and one that has been talked a lot about: https://www.mail-archive.com/casper@lists.berkeley.edu/msg09210.html. There are really only ways to mitigate how often it happens. Those are noted in the advice under the section Ubuntu 20.04 from the “Note on Operating Systems” on the CASPER tutorials site: https://casper-toolflow.readthedocs.io/en/latest/index.html#a-note-on-operating-systems. Specifically, bullet number two applies to you, “If you find the System Generator gets stuck during initialization or when compiling: There are some toolboxes that can cause this. We recommend only having the required toolboxes installed. See also this thread, for more information.”
Perhaps you would be willing to run Matlab 2022a and Vivado 2023.1 from the newer branch of CASPER tools? I believe on Ubuntu 20.04 there have been fewer cases of this issue with Matlab 2022a and Vivado 203.1 as opposed to Matlab 2021a and Vivado 2021.1.
