Abstract
PURPOSE:To detect the defect of a microcomputer program by simulating the interruption applied from an input/output device in a state approximate to that of a real device. CONSTITUTION:An interruption monitor mechanism 11 of a CPU simulator 1 delivers the interruption permitting information to an IO control simulator 2 as long as the interruption is possible. An interruption permission control mechanism 24 of the simulator 2 informs the interruption permission to an IO model 3 that delivered an interruption request. The model 3 sets an interruption type against the interruption request and returns the control to the mechanism 24. Thus the mechanism 24 informs the interruption type to the simulator 1 and an interruption execution control mechanism 12 of the simulator 1 checks the interruption types and delivers the control to the corresponding interruption routine. Thus the hardware interruption can be simulated in a state approximate to that of a real device. Then the defect of a microcomputer program can be detected.
