Minimal State Space Realization on Delay Rational Green’s Function-based Macromodel

Abstract

High speed interconnects at various design levels are commonly modeled mathematically to analysis signal integrity issues. In this paper, minimal state space realization method was applied in delay-rational model of multiconductor transmission lines. The proposed method ensured that state space converted from rational formulation did not contain redundant state variables. As a result, state space representations of the system can generate equivalent circuit optimally in macromodel synthesis. The experimental results showed that there was a reduction in the number of netlist nodes and the computational expense of time domain simulation.
