Accurate and closed-form spice compatible passive macromodels for distributed interconnects with frequency dependent parameters
Fast and accurate signal integrity analysis is becoming a major requirement in validation of high-speed designs. This demands efficient and accurate models for highspeed distributed interconnects. Also it has been demonstrated that, preserving passivity of the macromodel is essential to guarantee a stable global transient simulation. In this paper, an efficient method for the analysis of high-speed distributed interconnects with frequency-dependent parameters is presented. The proposed method enables representation of the distributed stamp in terms of simple delay and resistive elements. The new method while guaranteeing the passivity of the macromodel, provides significant speedup, and enables easy implementation. Necessary formulation and validation examples are given.
