Reading SVSEED set by IUS,vamanger

adwait

When the job is submitted to queue via vmanager and seed is set by IUS how to read that seed inside .sv or .v file. When I read it with $value$plusargs it returns warning saying the
the types do not match and +svseed value is 'random'. Is there anything available to get that seed directly ?

  • Normally you should not need to access the seed directly yourself, as NCSim takes care of seeding the SV RNG directly from the -svseed argument.

    If you really need to get the seed value yourself for some other purpose, then I'd recommend you use the "gen_random" value in the VSIF. This asks vManager to generate a random numeric seed before calling the test's run_script. For example:

    test my_test {
      sv_seed : gen_random;
    };

    Hope this helps.
