  • Method and apparatus for diagnosing an integrated circuit
    Patent number: 8516316
    Abstract: System and method for diagnosing failures within an integrated circuit is provided. In an embodiment, the apparatus includes a diagnostic cell coupled in series with a buffer chain. The diagnostic cell includes a plurality of logic operators that when activated invert a signal received from the buffer chain. The inversion of the signal from the buffer chain allows the diagnostic cell to determine the location of a failure within an integrated circuit previously determined by a scan chain design for test methodology to contain a failure.
