using auto-vias through SKILL

I have a list of bBoxes of path shapes of 0.05um width (M1, M2, M3 overlapping/stacked on each other) in my current hierarchy. I have dbIDs of shapes as well. I tried to use function "dbCreateViaShapeArray" but it requires calculations of how many vias we can place(and this could change upon different lengths of the overlapping paths, i could calculate the length of path by subtracting starting y and ending y from their bBoxes, but still it is not generalized for different path lengths). And also it is not giving equal enclosures of both the ends of the paths.

The requirement here for me is to use auto-via function somehow on these overlapping shapes somehow through SKILL code because auto-via is giving me required proper results.

So, how to use auto-via on these overlapping path shapes to get the desired result.

Hi Leonardo Vinci

Starting from IC617, you can use functions such as viaGenerateViasAtPoint to automatically create vias. It is the SKILL equivalent of autovia function. Please see $CDSHOME/doc/sklayoutref/sklayoutref.pdf for more details.
