Constant impedance scaling paradigm for interconnect synthesis

Abstract

On-chip global interconnects perceived as performance limiters for continued scaling of integrated circuits in nano-CMOS regimes highlight the importance of their proper design and optimization. A constant impedance scaling paradigm is proposed for systematic synthesis of complete interconnects physical parameters from system level performance metrics such as delay, power and wiring density. The methodology is illustrated for different system level targets and optimal physical parameters are deduced.
