    Hi,

    Im am trying to use do_extract_model to create a .lib file. I am using this in the top level of another netlist in  build gates. However I see that, when I run the flat netlist (no .lib used for sub block) I see some timing violations which I dont see on using the .lib file.

    When I study the timing report, I see that the sub block (with .lib) shows a different propagation delay which is much lesser than what it actually is. Can you please let me know the reason for this? And when extracting the .lib file how are purely combinational paths handled?

    Thanks,
    Arun
