Assura DRC and RCX batch run with SKILL

henriqueiesam

Hi everyone,


Can somebody please explain me:


1) How to start Assura LVS and RCX with a SKILL script?


2) With the script above. How to get some values (sca, scb and scc) of the extracted view?


This will be done with one simple transistor, but for many sizes and one at a time.

  • Hi henriqueiesam

    You can refer to COS article 11803100 for a sample SKILL which can execute Assura DRC, LVS and QRC extraction. Instance parameter values can generally be obtained as follows:

    a. Open the extracted view
    b. Select any instance
    c. Execute the following in CIW:

    cv=geGetWindowCellView()
    inst=css()
    inst~>sca

    You have to use a foreach loop to automate the process. E.g.

    foreach( inst setof(x cv~>instances pcreMatchp("mos" x~>cellName))
       printf("inst: %s sca: %L\n" inst~>name inst~>sca)
    ) ;foreach

    Hi Quek, when the SKILL script is executed, I get the following error:

    **************************

    Thanks for the reply.

    Hi henriqueiesam

    It looks like my script was only meant for PVS-QTS flow and not Assura-QTS flow. Sorry that I had remembered wrongly. Hope that it is still a good starting point for you to modify it for Assura-QTS flow.
