Establish connectivity on a text purpose layer to traverse hierarchy.

snee

We have several layouts where the designers did not place pins on their nets, but rather tagged them with text layers to pass LVS. We're looking for a way to use the existing text layers to propagate connectivity through hierarchy, without having to edit the underlying layout and place pins. Also, we do not want to simply generate the pins on the top level cell with leHiCreatePinsFromLabels(), but would rather modify the text layer to inherit the properties of a pin.

Does anyone know of a method to do this?

Thanks.

  • I don't think I really understand what you're trying to do. If you want connectivity in the database throughout the hierarchy, aren't you going to have to edit those cellViews anyway? In which case, why not add the pins?

    If you're talking about making sure that LVS recognises the text, that's a different question (in which case knowing the LVS tool would be important).

    Perhaps you can clarify your objective?
