Generate netlist with subckt statement for top level

Octavian

I'm generating a netlist from CIW using:

simulator('spectre)
design("libName" "cellName" "viewName")
createNetlist()

This works fine but I would like to enclose the top level cell in .subckt/ends statements, similar to other cells in the hierarchy. Is that possible using the skill/ocean interface?

 

Thanks,

  • Hi Matthew,

    I'm assuming that the version you mention is ICADV12.1.500.11 (as returned by "virtuoso -W")? If so, then it should be there, because it first appeared in ISR5 (ICADV12.1.500.5) and IC616 ISR3 (IC6.1.6.500.3).

    You will also need to be using MMSIM12.1.1 or later, otherwise it won't show up. Which spectre subversion are you using?

    Regards,

    Andrew.

  • Hi Andrew,

    You are correct, Virtuoso version is ICADV12.1-64b.500.11.  I am also pointed to MMSIM141_303, and spectre -version returns '14.1.0 64bit'.

    After reading your response I took another look at my script and found the issue.  I copied your envOptions code verbatim, but I had put it at the top of my script where I was already using envSetVal for some other settings.  That did not work.  Just now I moved the envOptions section down inside my gen_netlist procedure, just before I call createNetlist, and now it works.

    Thanks!
