Abstract
An approach for performing arbitrary waveform propagation through a logic gate using timing analysis results is described. In one embodiment, there is an arbitrary waveform propagation tool for determining an effect of noise on a digital integrated circuit having at least one logic gate. A timing analysis component is configured to perform a timing analysis on the at least one logic gate and a noise analysis component is configured to perform a noise analysis. A waveform propagation model synthesizer component is configured to dynamically synthesize a waveform propagation model as a function of the timing analysis. The waveform propagation model synthesizer component is further configured to apply an arbitrary voltage waveform comprising one of a noisy waveform or noise glitch waveform and determine an effect of the arbitrary voltage waveform on the at least one logic gate from the dynamically synthesized waveform propagation model.
