Latest Patents

Wei-Pin Changchein's latest patents include a method and apparatus for diagnosing an integrated circuit. This system provides a way to diagnose failures within an integrated circuit by utilizing a diagnostic cell coupled in series with a buffer chain. The diagnostic cell employs a plurality of logic operators that, when activated, invert a signal received from the buffer chain. This inversion allows the diagnostic cell to pinpoint the location of a failure within the integrated circuit, which is crucial for effective testing methodologies.

Another significant patent is related to a circuit and method for clock skew compensation in voltage scaling. This innovation addresses the issue of clock skew that arises when one power domain operates at a lower supply voltage. The circuitry selectively delays the clock pulse in one of the power domains to minimize skew by comparing clock pulses. The method iteratively determines the necessary delay to ensure optimal performance.
