Changing Pcell parameters with a skill script

menime54

Hi All,

I am trying to change the parameter of a pcell using a skill script.  I can change bolean parameters using:

 instance~>parameterName = nil

inst~>sourceFirst = nil

 If I try to write to a cyclic parameter the properites form changes, but the pcell is not affected.  And it eventually errors out when I manually try to change the properties form.

inst~>lastContactParam = "no contact"

I have found a way around it in my script.  I open the properties form and change the parameter on the form and apply the change, but this option takes a very long time to complete when I run my script over a large number of transistors

 leHiEditProp() geiPlSetPropValue("editorNum0" "parameter" "lastContactParam" "cyclic" 0) geiPlInvokePlistAction("editorNum0" "apply")

Is there a way to bypass the properties form to write to a cyclic field??

Thank you,

Stephanie

     Hi Stephanie,

    didn't hear about cyclic fields for PCells,
    is your cell really a "pure" Pcell or are there CDFs defined that behave similar to
    pcell-parameters but are defined separately?

    Perhaps you could try to inspect your cell by using the CDF-editor,

    CIW - Tools - CDF - Edit

    But, that's not the difference, you can manipulate CDF-parameters the same
    way as pcell-parameters.

    --> One possibility might be: the name of the parameter and the prompt in the
    properties form must not be necessarily the same as they are for PCells,
    so possibly you are trying to manipulate a non-existing Parameter by using an incorrect name?

    You should first check this by using the CDF-editor or by running cdfDump against
    your cell:
    cdfDump("LIB" "filename_to_dump_to" ?cellName "YOURCELL" ?level 'user ?edit t)

    hope this helps, have a nice weekend
