Methodology to simulate delta-I noise interaction with interconnect noise for wide, on-chip data-buses using lossy transmission-line power-blocks

Abstract

A new technique is described for reducing computational complexity and improve accuracy of power distribution and interconnect noise prediction for wide, on-chip data-buses. The methodology uses lossy transmission-line power-blocks with frequency-dependent properties needed for the multi-GHz clock frequencies. The interaction between delta-I noise, common-mode noise, and crosstalk is illustrated with simulations using representative driver and receiver circuits and on-chip interconnections. © 2004 IEEE.
