how to create netlist from schematic in ultrasim simulator netlist format hspice with ocean script

iqbalsahid

hi,

i tried with this script.

simulator( 'UltraSim)
design( "libname" "cellname" "schematic")
createNetlist(?recreateAll t)

but its creating spectra netlist format not hspice format.

how to do that?

  • You need to add:

    envOption('netlistFormat "hspice")

    to your script. You could have seen this if you had set it up interactively in ADE and then exported an OCEAN script (just to let you know how I found this out, for future reference).

    Regards,

    Andrew.

  • thanks Andrew that is so much helpful and working fine.
    But i modified the file accordingly you said. Its took old file for running. So i close the virtuoso and open it run then its coming fine.
    Is there any problem with my script or clear something?

  • I can't think of any good reason why you should have to exit virtuoso after making this change. It can't really take the old file unless you'd didn't save it.

    Andrew.

  • I also face that problem earlier with skill scripting. I am editing the file in Vim editor in terminal. then after saving i use (load "file_path") in virtuoso ciw. But sometime it show previous results.

  • Maybe you have some NFS synchronisation problem on your network. There's no caching of the files read by SKILL, so it can only be that when  you attempt to read the file off disk, it's not seeing the changes - this can only be a user problem or an OS problem, nothing to do with the Cadence tools themselves (I've never seen this behaviour). 

    I should point out that if the file is open in the SKILL IDE at the same time, you need to ensure that what the IDE is seeing is up to date (it should prompt you to say that the disk copy is different from what is displayed). However, you didn't mention using the IDE...

    Andrew.

  • Ok thanks for that I will check that. And I did't open IDE. directly loading in ciw .
