skill code to add netSet property on an instance (detail)

AndreyVolk

Dear Sirs,

I have an open schematic with many different instances.
(Cadence IC 5.1.41 Virtuoso Schematic)
How can I add to all the instants a "gdn33" netset with value "VDD" ?
"gdn33" this name netSet the properties.
"VDD" this name net in schematic.
I saw the answer
community.cadence.com/.../10777

But unfortunately my knowledge in the skill is very small.
Could you show the detailed code to solve my problem.

Thanks,
Andrey.

  • Andrey,

    If you have the instance Id, then you'd do:

    dbCreateProp(inst "gdn33" "netSet" "VDD")

    or maybe better still would be:

    dbReplaceProp(inst "gdn33" "netSet" "VDD")

    so that it doesn't complain if the property already exists - it just replaces.

    If you wanted to do it for every instance (not sure you necessarily want that) then you could do:

    cv=geGetEditCellView()
    foreach(inst cv~>instances
      unless(inst~>pin
        dbReplaceProp(inst "gdn33" "netSet" "VDD")
      )
    )

    Hope that helps.

    Andrew.

  • Dear Andrew,
    thank you very much.

    You completely solved my problem.
    Saved me a lot of time. And they saved me from tedious manual work.

    I do not know the Skill and would like to study Skill.
    Andrew, please advise which manuals and in what order to read to learn it?
    How to better learn skills?

  • We offer a number of training courses on SKILL (including the SKILL Language Programming class) - see Services->Training at the top of the page. 

    In terms of manuals, I'd start by reading the SKILL Language User Guide which talks about the principles of the language. There are then a number of reference manuals for particular application programming interface (API) functions for different applications and parts of the tools - plus there are lots of examples on support.cadence.com and in these forums.

    Regards,

    Andrew.

  • Dear Andrew,
    thanks for the answer.

    I am sorry. Probably everyone asks this question.
    It is clear that just need to learn.

    Regards,
    Andrey.
