  • Fault injection using boundary scan
    Patent number: 5428624
    Abstract: A system and method for fault injection utilizing boundary scan includes the provision of an additional fault injection register to the standard JTAG architecture in order to allow the intentional introduction of faults into a device or module forming part of a system under test. Through the use of the fault injection register of the present invention, faults may be intentionally introduced and the system response to such faults monitored and analyzed independently of the system software and without the use of mechanical probes or the like for introducing the fault. The system and method of the present invention is readily integrated with the existing test functions of the standard IEEE 1149.1 boundary scan architecture.
