Inductive interconnect width optimization for low power

The width of an interconnect line a ects the total power consumed by a circuit. A tradeo exists, however, between the dynamic power and the short-circuit power in determining the width of inductive interconnect. The optimum line width that minimizes the total transient power dissipation is determined in this paper. A closed form solution for the optimum width with an error of less than 6% is presented. For a speci c set of line parameters and resistivities, the power is reduced by almost 80% as compared to a minimum wire width. Considering the driver size in the design process, the optimum wire and driver size that minimizes the total transient power is also determined.
