PURPOSE:To check the whole of software after change with ease by providing a simulation input giving device which gives reset signals to microcomputers of two control units with a same timing and a comparison judgement device. CONSTITUTION:A control unit 1A before the software change and a control unit 1B after the software change are set in a cheker 3 connected a personal computer 2. A signal generator 4 is connected to input sides of each unit 1A, 1B. Normal and transient operation mode data are supplied to the computer 2, and according to the signal therefrom, correspondent signals are output from the generator 4. First, a reset signal is given and the sampling timing is synchronized. Then the transient operation mode data is given. At this time, pulse differential detained from directly the units 1A, 1B or through actual loads 6A, 6B are compared and judged by a comparison judgement unit 7. |
