extract connectivity using skill

posh

Hi all,

I am a new Skill User, iam trying to write a code for extracting a net from one cellview and put it into a different cellview (only the extracted net). i have read some previous threads but most of them were pointed to VXL. i do not have a VXL licence. so can anyone hint me how to extract a net using skill in VLE.

 

thanks

Harish Poshala

    Step #5 needs to be expanded, or else you can get incorrect results. If you have several L shaped polygons or paths, the bounding box of those shapes could overlap shapes which are not connected. You actually have to break all shapes into rectangles and then do the overlap check on each rectangle. This part is not trivial for polygons, although, as discussed in the linked post, dbLayerTile could help with this.
