Abstract

PURPOSE:To improve the efficiency of debugging work by storing plural conditions corresponding to operation states of a logical device and checking the order of occurrence of them and detecting the state transition of the logical device to stop debugging. CONSTITUTION:A debugging processing signal 100 which a logical device 10 sends is inputted to a memory 2, and contents of the address are sent as an order number 101 and is sent as an order number 102 through an output register 3. Numbers 101 and 102 are inputted to a comparator 4 and are checked, and an FF 6 is set to send a detection signal 104 if they are in a preliminarily set order. Next, a comparator 5 compares the number 101 with a preliminarily set end number 103, and a coincidence signal 105 is outputted if they coincide with each other. An AND gate 7 sends a debugging stop signal 106 when signals 104 and 105 coincide with each other. Thus, debugging is stopped by detecting the state transition of the logical device to improve the efficiency.
