question about pcell SKILL code

Hi

I got a legacy SKILL code for pcell from the company and need to modify it. Could someone explain to me the purpose of using dbReplacProp shown below ? I cannot find the info about it in Cadence documentation. Could I remove these two lines from pcDefinePCEll definition.

pcDefinePCell(list(ddGetObj(globaldata->library_name) "testa" "layout") 

...

   dbReplaceProp(pcCellView "viewSubType" "string" "maskLayoutParamCell")
   dbReplaceProp(pcCellView "function" "string" "transistor")

)

Thanks,

MC

    The maskLayoutParamCell viewSubType was something added by graphical PCells so that it effectively ran Tools->PCell (or something like that) when  you opened the layout for the PCell. That's not needed for a SKILL PCell.

    Similarly the function isn't needed either.

    Andrew.
