modify PCell parameter due to skill code

Two issues:

1. You're getting the CDF for the instance in the variable cdf and the vfoSetParam is using a different variable cdfData
2. You probably should check that cdf is non-nil (or even the right kind of component) before trying to set parameters. After all, using ~>instances will get all the pins and global taps etc as well as any devices in your schematic.

Hi Andrew,

I'm not clear for this. could you please help modify the code for me?

thank you very much

Hi Andrew,

I miss something. the cdf should be cdfData. 

thanks

cdfData=cdfGetInstCDF(inst)
when(cdfData
   vfoSetParam(cdfData "sdMtlWidth" "280n")
   vfoSetParam(cdfData "leftTap" nil)
)

Hi Andrew,

thank you very much. it does work now.

Hi Andrew,

I write a code in the following to modify the cells in a library. the code works in process a, but it doesn't work in process b. I found an interesting thing: I run the code first, it will moidfy one instance parameter; it will modify the next instance parameter when I run the code twice. 

my code:

procedure(modifyCDFParam()

   let((cv cvSch cdfData)

   cv=geGetEditCellView()

  cvSch=dbOpenCellViewByType(cv~>libName cv~>cellName "schematic" "schematic")

  foreach(inst cvSch~>instances

    if (inst~>libName==techGetTechFile(cvSch)~>libName

    then

    cdf=cdfGetInstCDF(inst)

    when(cdf~>sdMtlWidth  vfoSetParam(cdf "" "280n"))

    when(cdf~>leftTap  vfoSetParam(cdf "leftTap" nil))

       )

                )

       )
                )

when I run the code, the ciw report the error:

*** Error in routine putprop:

Message:*Error* putprop: first arg must be either symbol, list, defstruct or user type

Entering new debug toplevel due to error:

sorry, the "" should be "sdMtlWidth"

the whole code:

procedure(modifyCDFParam()

   let((cv cvSch cdfData)

   cv=geGetEditCellView()

  cvSch=dbOpenCellViewByType(cv~>libName cv~>cellName "schematic" "schematic")

  foreach(inst cvSch~>instances

    if (inst~>libName==techGetTechFile(cvSch)~>libName

    then

   printf("Proceeding the instance: %s\n" inst~>name) 

   cdf=cdfGetInstCDF(inst)

    when(cdf~>sdMtlWidth  vfoSetParam(cdf "sdMtlWidth " "280n"))   

    when(cdf~>leftTap  vfoSetParam(cdf "leftTap" nil))

       )

                )

       )
                )
