  • System and methods for fault path testing through automated error injection
    Patent number: 7020803
    Abstract: The system and methods described herein relate to testing and verifying the fault tolerance in fault tolerant systems. Fault logic integrated into a fault tolerant system permits automated testing of fault paths in system firmware and hardware dedicated to handling fault scenarios. Advantages of the disclosed system and methods include the ability to inject errors without the need to modify system firmware or hardware. Errors can be injected in a controlled manner and asynchronously to normal system firmware execution which permits improved coverage of firmware error paths. The automated error injection capability disclosed is applicable in both the development and production of fault tolerant systems.
