Methodology to Simulate Delta-I Noise Interaction with Interconnect Noise for Wide, On-chip Data-buses Using Lossy Transmission-line Power-blocks

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.
