Abstract :
The analysis and simulation of effects induced by VLSI interconnects become increasingly important as the scale of process technologies steadily shrinks. While most analyses focus on the timing aspects of interconnects, power consumption is also important. In this paper, the power distribution estimation of interconnects is studied using a reduced-order model. The relation between power consumption and the poles and residues of a transfer function is derived, and an appropriate driver model is developed, allowing power consumption to be computed efficiently. Application of the proposed method to RC networks is demonstrated using a prototype tool
