Reading PCell Properties/Parameters using SKILL

frasheed

 Hello All,

I have a PCell that has nfet layout and I am writing a SKILL code to open the layout and label the Gate, Drain, Source and Bulk in layout. For that I need to read the parameters that where is the Gate, Drain and Sourcein layout. I tried some commands like :

pcGetParameters , pcGetParamLabelDefn, pcGetParamLabels, pcGetParamLayers but all of them are given me "Nil". Can anyone help me what's wrong ? Is it because the PCell doesn't have any properties ?

or is there any better way for labeling ?

Thanks

P.S: I didn't created that PCell and I am very beginner to SKILL.

  • Hey Ted,

    Thanks for your reply.

     

    [UPDATE]: I just read in skdref.pdf that under terminal, pins attributes can't be modified

    so how I can I update pins in my cell after creating the bulk pin?

    I know this command can solve my problem

    dbSetq(cellView~>instances~>instTerms~>term b_pin pins)

    but I cam't set pins as pins is already the property , so I need to update and I am confused how to choose that "nil" pin
