  • Test method and apparatus using energy consumption ratio
    Patent number: 6513137
    Abstract: A method of fault testing an electronic circuit by measuring the ratio of the power drawn by a circuit under test to the average power drawn by good circuits as the input is driven by input vectors V1 and V2. Input vectors V1 and V2 can be selected in accordance with an algorithm to maximize the difference in power drawn by the faulty circuit relative to the good circuit. The method is useful in detecting redundant logic faults that are not detected at the outputs of the circuit being tested.
