A multiconductor transmission line methodology for global on-chip interconnect modeling and analysis

Abstract

This paper describes a methodology for global on-chip interconnect modeling and analysis using frequency-dependent multiconductor transmission lines. The methodology allows designers to contain the complexity of series impedance computation by transforming the generic inductance and resistance extraction problem into one of per-unit-length parameter extraction. This methodology has been embodied in a CAD tool that is now in production use by interconnect designers and complementary metal oxide semiconductor (CMOS) process technologists.
