Inductance Aware Interconnect Scaling
This paper introduces a new global-tier interconnect scaling scheme which ensures that inductance effects do not start dominating the overall interconnect performance. It is shown that for unscaled global lines, inductance effects increase as technology scales while for the scaling scheme proposed by ITRS [1], interconnects become extremely resistive and, while inductance effects diminish with scaling but the performance, specifically, delay per unit length, degrades with scaling. The effect of the proposed global interconnect scaling scheme on optimized driver size, interconnect length, delay per unit length and total buffer area is quantified and compared with the unscaled and the ITRS cases. It is shown that the proposed scaling scheme improves the delay per unit length without degrading inductive effects or increasing buffer area with scaling.
