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

  • Hi Ted,

    thanks :)

    I tried this compact code also inside if my pcell code... and cv2 still has ROD handles after re-opening. (modification: behind ?rodObj I put newObj instead of cv2) That means ROD should be o.k.

    So I need to look deeper, why my ROD handles vanish, when the generator was called from the pcell. Basically I do exactly the same in my code. Before the dbSave I still have handles, but if I re-open the layout later from the libManager I don't find userHandles...
