In this paper, the authors present a novel, simple and accurate delay estimation model for single interconnect and tree interconnects, which is based on new Matrix Pade-Type Approximant (MPTA). The proposed model provides a simpler rational function approximation for estimating delay and overshoot in lossy VLSI interconnects. Computational complexity is reduced by considering rational function denominator as scalar polynomial and avoiding matrix inversion. With the reduced order lossy interconnect transfer function, finite ramp responses are obtained and line delay and signal overshoot are estimated.
