To verify the validity of fault control measures, a verification platform with software fault injection and hardware fault injection is developed to conduct fault diagnosis measures for MCU control system. For the faults occurring in the internal units of a controller, program debugger is employed to simulate software or hardware faults by varying the data; for the faults occurring in peripheral circuits, a circuit of fault-settings is employed to simulate hardware faults, i.e., open-/short-circuit and electrical level variation. This verification platform is applied to evaluate software measures to control the faults/errors in accordance with IEC60335/IEC60730/UL1998/CSA22.2.08, and a case of induction cooker is presented shows how it works. Experimental results show that the verification platform runs stably and accurately, and has a big value in practice.
