Abstract

We present new macromodeling techniques for capturing the response of a CMOS logic gate to noise pulses at the input. Two approaches are presented. The first one is a robust mathematical model which enables the hierarchical generation of noise abstracts for circuits composed of the precharacterized cells. The second is a circuit equivalent model which generates accurate noise waveforms for arbitrarily shaped and timed multiple-input glitches, arbitrary loads, and external noise coupling.
