SKILL to modify layout parameter

40Ford

I have written SKILL functions to change or add parameters to a cellView. What I need to do now is grab the value of a parameter from a schematic and copy that value to the corresponding layout.

The parameter is called "connectivity" and I only want to change the value in cell "option". Yes, "option" is the cellName.

I know how to grab and instance and grab the property in SKILL but what I can't understand is how to know I'm getting the corresponding layout view for that instance.

 Any suggestions?

  •  This may have worked. I haven't thoroughly verified it yet.

     procedure(reset_default_param()
        let((clv csv instList layInstList schInstList schInstName schParamValue numelem)
            clv = geGetEditCellView()
            csv = dbOpenCellViewByType(clv~>libName clv~>cellName "schematic" "schematic" "r")

            layInstList = clv~>instances
            schInstList = csv~>instances

            schInstName = setof(inst schInstList inst~>cellName == "option")~>baseName
            schParamValue = list()

            foreach(inst schInstList
                if(inst~>cellName == "option" then
                    schParamValue = append(schParamValue list( dbSearchPropByName(inst "connectivity")~>value))
                ) ; end if
            ) ; end foreach

            dbClose(csv)

            numelem = 1
            foreach(inst layInstList
                foreach(elem schInstName
                    if(inst~>baseName == strcat("|" elem) then
                        printf("\nmatch")
                        dbReplaceProp(inst "connectivity" 'string nthelem(numelem schParamValue))
                    ) ; end if
                ) ; foreach
                numelem = numelem + 1
            ) ; end foreach
        ) ; end let
    ) ; end procedure
