How to use skill to change PCell parameter like using Edit Instance Properties to change parameter ?

Charley Chen

Hi All,

When using Pcell , press  q to use "Edit Instance Properties" to change parameter (e.g.  length) ,

in cdf  , it has callback ,  everything is right according to callback function . Different length has it different result in Pcell.

Now I have many Pcells needs to changed  parameter - length (from 2um to 4um) by  "Edit Instance Properties" ,

Is there any approach to do that ? (Not manual use "Edit Instance Properties" to change each Pcell's parameter ?

After changing parameter - length , its result should same as using "Edit Instance Properties" .

 

Thank you.

Charley

  • CDF callbacks are only executed during the interactive editing of the parameters through the Edit Property form or the Edit Property Assistant (IC6.1). If you are changing them programmatically, you have to execute the callback. Here is a way to do it:

    ;; Get the instance
    inst = car(selectedSet())
    ;; Instance CDF
    cdfgData = cdfGetInstCDF(inst)
    inst->length = newLength
    param = cdfFindParamByName( cdfgData "length")
    when(param->callback
      evalstring(param->callback)
    )
