How to avoid compiling Verilog/sytemVerilog views every time you netlist (AMS)?

iguerra

Hi,

I would like to know if is possible to avoid compiling the Verilog/sytemVerilog views every time you generate an AMS netlist in ADE-L (based on a config file with a sytemVerilog template).

The compilation time is extremely long and I only want  to confirm if there is no netlist errors (no simulating).

Thanks.

    First of all, cell-based is obsolete nowadays - you really should move to using UNL (especially with recent versions, as you're presumably using if using ICADV - you didn't say which number though). However, regardless of that...

    1. Unchecking the "incremental" options will just cause it to compile all, I think. So you should check the incremental options.
    2. There normally isn't a "clean snapshot and pak files" option with cell-based netlisting.
    3. The method you said about unloading the incisive module makes absolutely no sense to me. Some level of compilation is required to allow it to see hierarchy underneath textual views.
    4. The vmsNcvlogExecutable is related to when you are "checking and saving" the textual view - nothing to do with netlisting. So messing with that makes no sense either.

    One thing to be aware of is that it may still call ncvlog during netlisting - sometimes this may take little time as it's incremental though.

    However, you really should explore moving to using the Unified Netlister (UNL) technology instead.

    Regards,

    Andrew.
