Analytical timing model for inductance-dominant interconnect based on traveling wave propagation

Abstract

As accurate and efficient timing prediction is very important for integrated circuit design, an analytical timing model for inductive-effect dominated resistance–inductance–capacitance (RLC) transmission line with resistive driver and capacitive load is proposed by virtue of traveling wave propagation and perturbation technique. This model is theoretically stable and computationally efficient. Comparison with other analytical and SPICE models illustrates that this timing model can achieve excellent accuracy for inductance-dominant interconnect. Incorporating with decoupling technique, this model could be readily extended to coupled interconnects.
