This paper presents a substrate noise analysis methodology that employs chip-level substrate modeling based on F-matrix computation and digital substrate-noise injection modeling with a time-series divided parasitic capacitance model for time-domain power-supply current estimation.System-level simulation models generated accordingly to the methodology provide reliable substrate noise waveforms.Simulated waveforms for practical digital circuits on a 0.6-?m CMOS 4.5-mm square chip are well consistent with measurements with a 100-ps 100-?V resolution.Peak-to-peak substrate noise amplitudes for reduced-substrate noise as well as conventional designs show roughly the error of 10%compared with the measurements.
