Abstract:
This paper presents a sensitivity-based wiresizing algorithm for interconnect delay optimization of lossy transmission line topology under MCM technologies. Our approach computes the maximum delay and its sensitivities with respect to the widths of wires in the topology via high order moments based on an exact moment matching model[6]. Compared with other approaches, it achieves analytical sensitivity computation and calculates higher order moments (sensitivities) recursively from lower order moments for tree network. It can yield optimal wiresizing solution for interconnect delay minimization. Experiments show that the delay estimation using high order moments is very accurate compared with SPICE simulation and our approach can reduce the maximum rising delay by over 60 % with small penalty in routing area. Besides delay optimization, the final solution eliminates the overshooting of response waveform and is robust under parameter variations.
