Fault isolation with abstracted objects

摘要

In response to a notification of a fault captured in a system, a fault isolator serially analyzes each clock object to determine captured faults associated with the clock object. For each of the clock objects determined to have a captured fault, the fault isolator initiates a repair action for the chip represented by the clock object. The fault isolator concurrently analyzes the non-clock objects to determine captured faults associated with the non-clock objects after analysis of the clock objects. For each of the non-clock objects determined to have a captured fault, the fault isolator initiates a repair action for the chip represented by the non-clock object.

1. A method comprising:
generating, for each of a plurality of chips in a system, a clock object and a non-clock object, wherein the clock object indicates at least one of data and program code for clock related functionality of the chip and the non-clock object indicates at least one of data and program code for functionality of the chip that is not related to clock functionality; in response to a notification of a fault captured in the system,
serially analyzing each of the clock objects to determine captured faults associated with the clock objects;for each of the clock objects determined to have a captured fault, initiating a repair action for the chip represented by the clock object; andafter said serially analyzing each of the clock objects,
concurrently analyzing the non-clock objects to determine captured faults associated with the non-clock objects;for each of the non-clock objects determined to have a captured fault, initiating a repair action for the chip represented by the non-clock object.
