Get all other cells used in a given cell

CClauson

Hello,

Given a cell, I'm wondering if there's any easy way to programmatically get all other cells used in that cell's design.

Code looks something like this:

;;winId has type "window", as tested
;;by function wtypep()
myCell = windId->cellView

Now, given myCell, how can I create a list of other cells that are referenced in myCell's design?

Also, I have a more general question:  If I'm given a type in SKILL, is there any easy way of finding the documentation for what members it has, like Javadoc?  If this were Javadoc, I'd go to the "window" type, see that it has a "cellView" member.  I'd then go to that type's doc, which would probably answer my question.

Thanks in advance for any advice that can be offered.

  • Okay, I think I got this worked out.  Here's the solution I ended up using:

     procedure(getSchematicDBsInSchematicDBs(cvId)
        prog( (
            ;;local variables
            retlist
            newcvId
        )
        retlist = nil ;;initialize return list to empty list
        foreach(master cvId->instanceMasters ;;iterate through symbol cellviews referenced in this schematic
            ;;try to find a schematic cellview for this symbol cellview,
            ;;will return nil if none can be found (and, unfortunately, issue a warning in the CIW!)
            newcvId = dbOpenCellViewByType(master~>libName master~>cellName list("schematic"))
            if(newcvId ;;if didn't return nil
                retlist = cons(newcvId retlist) ;;append to beginning of return list
            )
        ) ;;end foreach
        return(retlist)
        ) ;;end prog
    )

    The only downside of this is that it issues warnings in the CIW.  If there was some way to avoid that it would be nice, but this works reasonably for now.

     Thanks for the help!
