  • Method of testing susceptibility to failure of functional circuitry embodied in an integrated circuit
    Patent number: 6111422
    Abstract: A test device is formed on a chip which allows the susceptibility to failure of functional circuitry formed on the chip to be tested. The test device allows aggressive design of chips which include sensitive circuitry, such as precharged dynamic logic, by testing whether deviations from the design specification introduced during manufacturing of the chip are sufficient to cause failure of the functional circuitry.
    Type: Grant
    Filed: April 30, 1999
    Date of Patent: August 29, 2000
    Assignee: International Business Machines Corporation
    Inventors: Salvatore Nickolas Storino, Robert Russell Williams
