  2. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    In a Linux system, for example, the watchdog daemon can be configured to attempt to perform a software-initiated reboot, which may be preferable to a hardware reset as it allows file systems to be safely unmounted and fault information to be logged prior to the reboot. It is essential, however, to have the insurance provided by a hardware WDT ...

  3. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...

    The ability to use multiple software programs adding flexibility; The identification and clearance of fault code; Data shown by intuitive graphs and charts; The extent that a PC tool may access manufacturer or vehicle-specific ECU diagnostics varies between software products [42] as it does between hand-held scanners.

  7. Automatic test pattern generation - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_pattern...

    ATPG (acronym for both automatic test pattern generation and automatic test pattern generator) is an electronic design automation method or technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects.

  8. Failure detector - Wikipedia

    en.wikipedia.org/wiki/Failure_detector

    The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.

  9. SAPHIRE - Wikipedia

    en.wikipedia.org/wiki/SAPHIRE

    In 1986, work commenced on the precursor to the SAPHIRE software – this software package was named the Integrated Reliability and Risk Analysis System, or IRRAS. IRRAS was the first IBM compatible PC-based risk analysis tool developed at the Idaho National Laboratory , thereby allowing users to work in a graphical interface rather than with ...
