Abstract :
Summary form only given. We present a new AnalogRouter, specifically developed to address the problems of current densities and electromigration in the routing of multi-terminal, non-planar signal nets in analog circuits. The contributions of our work are: a new current characterization method based on current vectors attached to each terminal; current-driven Steiner tree generation which effectively determines all branch currents prior to detailed routing; and a run-time and memory efficient detailed routing strategy which addresses all features of current-driven circuits, particularly varying wire widths
