  • Techniques for performing a Logic Built-In Self-Test in an integrated circuit device
    Patent number: 7873890
    Abstract: A method, system and computer program product for performing device characterization Logic Built-In Self-Test (LBIST) in an IC device. Test parameters of the LBIST are saved in a memory of the IC device, and nominal operational parameters of the IC device are used to define a signature of the LBIST. A determination whether the LBIST is passed or failed is made within the characterized IC device.
    Type: Grant
    Filed: June 30, 2008
    Date of Patent: January 18, 2011
    Assignee: International Business Machines Corporation
    Inventors: Abel Alaniz, Robert B. Gass, Asher S. Lazarus, Timothy M. Skergen

  • Proactive automated calibration of integrated circuit interface
    Patent number: 6965839
    Abstract: An integrated circuit device and system of devices in which a device interface incorporates dynamic, elastic calibration facilities. The interface includes a calibration manager and circuitry for monitoring the interface signals to detect the presence of signal skew, delay, or other degradation. If the monitor detects an out-of-calibration interface, the calibration manager initiates a dynamic calibration procedure. The calibration manager can also initiate the dynamic calibration procedure in response to an event such as the detection of a correctable error on the interface. By proactively monitoring the interface for degradation, the calibration manager is responsive to environmental changes as they occur and is efficient in its use of the calibration procedure by invoking it only when calibration is required.
