  •  This requirement may be either part of DFM or just out of curiosity question.

    Usually new layout enginners or even few experienced engineers use polygons instead of paths. In such cases auto-contact doesn't work IMO. And when polygons are used engineers use few vias than can be accomodated. Usually this practice is profound among engineers new to layout. In technologies like >0.18um engrs use only 1 or 2 vias (!= power nets).
