Efficient transient simulation of high-speed interconnects characterized by sampled data

In the past, Pade synthesis has been successfully applied to the analysis and simulation of high-speed interconnects. However, Pade synthesis (via moment-matching method) is not quite suitable for the analysis of interconnects characterized by sampled data, since the derivatives of system functions at selected expansion points are not easily obtained. This paper describes an efficient simulation method of arbitrary networks characterized by sampled data. Since no numerical inversion is required to obtain the transient response, nonlinear elements are handled efficiently. The example of arbitrarily terminated interconnects characterized by measured scattering-parameters is presented to demonstrate the computational efficiency and accuracy of the method
