Abstract
A computer determines a threshold signal voltage of a semiconductor device. The computer determines a first expected signal propagation time for a signal travelling through a first test path of the semiconductor device. The computer transmits a first signal through the first test path. The computer measures a signal voltage and signal propagation time of the first signal. The computer determines that the signal voltage of the first signal does not reach or exceed the threshold signal voltage within the first expected signal propagation time. The computer determines that the first test path contains a defect.
