Abstract
In this paper sensitivity study on wire sizing optimization supplementary recommends that there exists a small set of “globally” optimal wire widths for a range of interconnects. We examine general and efficient methods for computing such a “globally” optimal wire width design and show rather surprisingly that using only two “predesigned” widths for each metal layer, we are still able to achieve close to optimal performance related with that by using many possible widths, not only for one fixed length, but also for all wire lengths assigned at each metal layer. Our wire width planning can consider different design objectives and wire length distributions.
