Abstract: A test technique that may be implemented in an automated test system for testing semiconductor devices. The test technique may enable the fast detection of a signal transition, such as an edge, within a waveform and the timing of that event. Circuitry within a digital instrument that can be quickly and flexibly programmed may, at least in part, implement the test technique. That circuitry may be simply programmed with testing parameters, such that application of the technique may lead to faster test development and faster times. In operation, that circuitry receives parameters specifying parameters of a window over a waveform in which samples of the waveform will be taken to detect the signal transition. The circuitry may convert these parameters into control signals for other components in the test system, such as an edge generator or pin electronics, to take a programmed number of samples at desired times.
