The purpose of this work is two fold: first, to quantify and establish future trends for dynamic power dissipation in global wires of high performance integrated circuits; and second, to develop a novel and efficient delay-power tradeoff formulation for minimizing power due to repeaters, which can otherwise constitute 50% of total global wire power dissipation. Using the closed form solutions from this formulation, power savings of 50% on repeaters are shown with minimal delay penalties of about 5% at the 50 nm technology node. These closed-form, analytical solutions provide a fast and powerful tool for designers to minimize power.
