Abstract
Method and apparatus for detecting and analyzing effects of noise in a digital circuit that arises from a coupling of signals produced by switching of a first gate and a second gate in a timed relationship. Where each of a first gate and a second gate can switch within a selected switching time interval, the gate switching effects are combined and the second gate output signal is analyzed with reference to the first gate input signal. Otherwise, the gate switching effects are not combined. When the second gate output signal satisfies at least one of three criteria, this condition is interpreted as indicating that the second gate permits propagation of a noise pulse produced at the first gate.
