Modeling of RLC interconnect lines

Abstract

Simple uniform reduced order model is used to model an RLC interconnect line. Few number of sections are shown to achieve high accuracy of modeling the RLC interconnect. Waveform characterization is used to evaluate the accuracy of the adopted model. As compared to RC lines, five times the number of sections is sufficient to model RLC lines. The model is shown to be accurate for wide range of relative impedance of the driver, the line, and the load. The model provides a simple and quick mean to characterize an RLC interconnect which is necessary for performance evaluation in digital circuits.
