PURPOSE: To automatically check fault processing under various condition by making it possible to generate a false fault for checking a fault processing function on an optional place at an optional timing by a dummy fault generating instruction(FFGI). ;CONSTITUTION: This dummy fault setting system is provided with a diagnostic processor(DGP) 1 for defining and generating an FFGI for generating a false fault and an exclusive signal line 3 for forming a dummy fault designation applied from the DGP 1 to a specified device, which is provided with a function for generating a false fault. A dummy fault is designated from the DGP 1 to the specified device by the FFGI through inter-processor communication and the specified device is provided with a microprocessor for generating a dummy fault and a function for generating the dummy fault by starting the microprogram. Since the dummy fault can be optionally generated by the FFGI, the fault processor in a computer system can be automatically checked under various conditions for fault processing.;COPYRIGHT: (C)1993,JPO&Japio
