How to call a Pcell?

http://sourcelink.cadence.com/docs/files/Release_Info/Docs/skdfref/skdfref07.02/chap2.html

The list of parameters depends on the parameters available on the pcell you are placing. If it is your own pcell, then you should know what these parameters are. If you want to know what parameters are available on a pcell, do the following:

1. Place an instance of a pcell in Virtuoso
2. Select that one instance. In your CIW, css() will give you the "car of the selected set" which is essentially the database object of what you just selected.
3. From this database ID, you can find all of the parameters:
To get all the attributes and values of each parameter for the master of this instance:
css()~>master~>parameters~>value~>??
To just see the parameter names:
css()~>master~>parameters~>value~>name
To just see the current values:
css()~>master~>parameters~>value~>value
To just see the valueTypes:
css()~>master~>parameters~>value~>valueType

Now, you can construct your l_params (list of parameters) for dbCreatParamInst using any of the parameters found in the previous step. You'll need to know the name, valueType and value you wish to set. You only need to include parameters whose default you wish to change.

Example:
    master=dbOpenCellViewByType("myLib" "myPcell" "layout")
    paramList = list(
        list("w" "float" 10.0)
        list("h" "float" 5.0)
    )
    dbCreateParamInst(geGetEditCellView master nil 0:0 "R0" 1  paramList)
