Find the area which not overlapped by some layer.

Sharif H N

Hello there,


I want to highlight the area which is not overlapped by some layer. For ex:- Highlight the area in a stdcell which is not covered by diffusion.

Any help in this regard within couple of days will be highly appreciated.

Thanks in advance..

  • Create a rectangle on a dummy layer (e.g. y0) which is the size of the cellView bBox (i.e. cvId~>bBox), and then collect all the shapes on the diffusion layer (something like car(exists(lpp cvId~>lpps lpp~>layerName=="diffusion" && lpp~>purpose=="drawing"))~>shapes, and then pass these two to dbLayerAndNot to find the region of the bBox which is not diffusion.

    Regards,

    Andrew.
