Abstract

A method for establishing standard cell power connections is disclosed. The method generally includes the steps of (A) calculating a power consumption of a plurality of logic cells receiving power directly from a power rail, (B) removing at least one excess via from a plurality of vias directly connecting the power rail to a power mesh in response to the power consumption and (C) routing a signal through an area where the at least one excess via was removed.
