  • Constant-current VDDQ testing of integrated circuits
    Patent number: 6661246
    Abstract: Integrated circuit analysis is enhanced via a method and system for detecting defects associated with particular logic states of an integrated circuit. According to an example embodiment of the present invention, a constant current supply is applied to an integrated circuit. The voltage across the constant current supply is detected for each of a plurality of clock cycles of the integrated circuit, each clock cycle being representative of a logic state of the integrated circuit. The voltage detected at each clock cycle is compared, and the comparison is used to analyze the integrated circuit for a defect.
