Abstract

PURPOSE:To check simply control information for normalcy, by forecasting a control signal for the next status transition of automatons on a basis of statuses of automatons and control signals and comparing this forecasted control signal with an actual control signal. CONSTITUTION:An address generating part 5 combines status values of automatons A, B, and C and values of control signals in controlling circuits of automatons to generate address information to a storage circuit 6. Status values of the control latch and the control signal in an objective device which are forecasted on a basis of status values indicated by this address information are written preliminarily in the storage circuit 6 for forecasting control information which is designated by address information of the generating part 5. When transition conditions of automatons A, B, and C are satisfied, information such as outputs of controlling circuits in automatons is set to a register 7. Output data from the circuit 6 is compared with contents of the register 7 by a comparing circuit 8, and a check bit 9 becomes 1 if they do not coincide with each other.
