Where is the rodObj stored?

Sylvio

Hello,

I found an annoying behavior (bug?) of rodGetObj(...)

For IC6 I implemented a new VXL interface for layout generators (pcells which display generated/stored layout), which avoids wrapping menus. Unfortunately, all cells which are generated over this new interface (e.g. pick from schematic) don't have ROD handles, which are needed for higher level generators...

I seems, that rodGetObj("" cellView) does not create the ROD-object in the specified cellView but in pcCellView, when called from the body of a pcell...

In the documentation there is a note, that the second argument (cellView) is optional, if rodGetObj(..) is called from pcell context.

So I was sure that "optional" means something different from "is beeing ignored", isn't it?

My question is: Is this behavior intended? Is there a workaround (e.g pretend non-pcell context)?

Best Regards,

Sylvio

    You can make a master a ROD object using rodGetObj. Inside the pcell you have to open the cellView master for append and add the RODness and handles directly to the master:


           cv2 = dbOpenCellViewByType( "PDK_devices" "rodTest2" "layout" "maskLayout" "a" )
          newObj = rodGetObj( "" cv2 )
          rodCreateHandle( ?name "alignLowerLeft" ?rodObj cv2 ?type "point" ?value car(cv2~>bBox) )
          dbSave( cv2 )

      The master has to be open for edit, you only have to create the handle(s) once in the master, all other instances will have that handle.
