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?

  •  Hi Theopan,

     I appreciate your response. It is a parameter in a layout cell that I'm am trying to set.  However the value of the parameter comes from the corresponding schematic view property.

    The difficulty for me is not setting parameters. What I've been unable to figure out is how to extract that value from the same instance in the schematic.

     I have a cell with numerous instantiations of the 'option' cell. The instantiations in the schematic are using pPar("var") as value for the "connectivity" property. In the layout the connectivity parameter is hardcoded to an integer value. What I want to do is grab the value from the schematic instantiation and set it to the value for the corresponding layout instantiation.

     I can get the values of each schematic instantiation in a list but I haven't yet been able to get the values set is the correct layout instantiations.

     Hope that makes sense. This is one of those things that is really actually very simple to show but difficult to explain.

    Cheers,
