how to pass CDF parameter's value of an instance in schematic pcell to CDF parameter of schematic pcell

 Hey Andrew,

Sorry for not being able to describe it correctly, being a novice in this field. Here's an example of a section of the code that I am working on. I am calling the pcell code first (pcDefinePCell and my_schpcell_code) followed by the code to create the CDF for my schematic pcell. I have also included the relevant section of the cdfdump I performed on the foundry's pcell.

    (gw "float" 5.0)
    (gl "float" 5.0)
    (gtotcap "string" "1p")

  my_schpcell_code(pcCellView gw gl garea gtotcap)

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

 I hope I have decribed it correctly this time. When I instantiate the schematic pcell that I created and change it's properties, I see that the callbacks get called first followed by my schematic pcell code. So should I be reversing the order in which I tried to create the pcell and the cdf? Am I using the correct way to create the schematic pcell and its CDF?

Thanks,
