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

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.
