An Accurate Time Domain Interconnect Model Of Transmission Line Networks

In this paper, we present a new time domain model of interconnects modeled as transmission Line networks, Each element of the characteristics of a transmission line is modeled by a principal part and a remainder. The principal part consists of an impulse and an exponential function, whose Laplace transform matches the original function at infinity frequency with order 1 and at zero frequency with order 0. The remainder in the time domain consists of a cubic polynomial for a single line and a piecewise cubic polynomial for coupled lines, The model is stable, accurate, simple, and efficient to use.
