skill script to add layout pin for given metal intersect

There's a lot question of the environment and results:

Are the metals at cellview or in hierarchy?

Is there connectivity on the wires, labels or something else?

Is there more than one intersection?

Maybe the quickest way to solve the problem would be to use leHiMarkNet.

Then save the markNet of the two nets and do a Boolean on the intersections.

Hi Paul,

Metal are at cellview.  There is connectivity on wires. 

There are more than one intersection.

 leHiMarkNet may not work since I expect atleast 5-6 thousand intersection point. Its massive layout.

I'd probably use dbLayerAnd or maybe abeLayerAnd if you need the capacity - this would find the overlapping regions of metal9 and metal10 and end up with a set of candidate pin shapes (presumably on metal9 - you didn't say). You could then iterate over the list of shapes and for each use dbShapeQuery to find the shape on metal9 underneath the rectangles you've created. Then use dbCreatePin using the ~>net of that shape and the rectangle you've found from the dbLayerAnd operation as the pin figure.

Seems a bit of an odd requirement though - presumably you'd end up with a lot of pins which might not be terribly accessible - but maybe I can't visualise what your layout looks like. It's unlikely to be anything that is a standard feature because it sounds rather specific to how your  layout is constructed.

More questions or possible ways to get a solution.

Are you looking for help on writing or something already written?

Is there more than two layers involved?

You could do a search for the two layers with the nets you want copyFig to a tmp layer and do a Boolean on the intersections to output your pin locations

dbCreatePin from the Boolean nad delete the tmp shapes.
