PCELL's and warPCELL's

Patrick1982

Hi Everyone,

 I'm currently working on some pcells with Cadence.  I am using standard IBM pcells and I am using the "Inherited Parameters" option i.e. I am using a resistor and I am inheriting the Width and Length, and I am caliing them resW and resL, respectively and these are set as a "string".  The problem I am having (and I'm sure there is a simple answer to this) is I want to use the parameters resW and resL in a stretch command but I am getting the following warning:

 *WARNING* ("dbCreateParamInst" 62 t nil ("*Error* dbCreateParamInst: Invalid string" 17.92))

Does anyone know how to fix this?

 Also, does anyone have any information on warPCELLS?  I am currently using Cadence 5.1.4 but I will hopefully be migrating to 6.1 shortly, in the prvious company they were just rolling out 6.1 and I was led to believe that warPCELLS were already setup or very easy to setup, so any information on pcells for either versions with be great.

 

Thanks very much,

Patrick

  •  Hi Patrick,

    I have no idea what a "warPCell" is, sorry, perhaps it is a custom creation, part of a PDK (e.g. IBM since you mentioned them) or some other form of third party offering?

    Also I am not clear on what you mean by inherited parameters - perhaps this is something specific to the IBM Pcells that you mentioned. You might need to provide more detail - I do a fair amount of work with PCells and I haven't a clue what you are asking!

    Regards,

    Lawrence.
