  • Integrated circuit fault testing implementing voltage supply rail pulsing and corresponding instantaneous current response analysis
    Patent number: 5483170
    Abstract: A method and apparatus for detecting faults in digital, analog, and hybrid integrated circuits is disclosed. A single test vector employing bias voltage on input used in conjunction with pulsing the power supply rails is used to allow detection of the various faults which may be present. The instantaneous rail current (i.sub.DD) is then employed for analysis of the circuit, preferably by neural network.
