dbGetTrueOverlaps - abutting layers

dakuang01

Hi,

I'd like to make a layout cellview with CB layer for pad opening and its own pad pin from original layout so I'm using dbGetTrueOverlaps function.

There is an issue I cannot get full size of CB layer by using the function. Whole CB layer is octagonal shape but it is made of two shapes which are seperated with rectangle inside and rest of it outside. The shapes are abutting each other without any gap. But I only can get rectangle CB layer by using dbGetTrueOverlaps.

Do you have any good idea I can get whole CB layer?

Thanks,

Jungyoon

    A picture would help (doesn't have to be a screenshot, just a diagram....).

    I can tell you dbGetTrueOverlaps will find polygons (not just rectangles) if they overlap the bbox you give it, and are on the correct lpp.

    But if you want the whole CB layer anyway, maybe you should try dbLayerOr?
