Find the metal polygons having a pin

shazzy

I have some metal polygons in an instance and that is called in some other other celllview on which the pins are placed.

 

I want to find only those the metal polygons which have pin label over them. 

 

I have written a code wherein the polygon is broken into rects and then pins are searched in  the rects so created, but that process involves a lot of loops thus being tedious and memory hungry. Also, checking net or pin properties of the metal ain't working.

 

Could you please share any new code ideas wherein the desired metal polygons can be found

    The usual way of doing this kind of thing would be to find all the labels, and then use dbGetOverlaps with a zero-sized box using the ~>xy attribute of the label to find the shapes underneath. Not sure why you need to break the polygon up into rectangles.

    Hard to give advice without seeing precisely what you're trying to do and what you're doing right now.
