On the Modeling and Analysis of Crosstalk Noise in Nonidentical Lossy Interconnects

Abstract

The accurate and comprehensive modeling of interconnects system is crucial due to its effects on speed, signal integrity, and performance of the entire circuit. The novel idea of this article is to apply an efficient method to analyze crosstalk and delay of the lossy coupled interconnects system in generalized identical and nonidentical forms. For this purpose, a simple model containing capacitive and inductive coupling features is proposed under arbitrary excitation sources. More specifically, it gives comprehensive and accurate closed-form expressions according to transmission line theory to take both crosstalk and delay into account. The proposed coupling noise model is used to deal with the impacts of functional and dynamic crosstalk. Moreover, the voltage and current waveforms are efficiently calculated. The resulting crosstalk waveforms are in decent agreement with those obtained using Advanced Design System simulator. The presented technique could be extended to N coupled lines, opening new avenues to analysis of integrated circuit interconnections.
