PURPOSE:To grasp the quality of a program in a system to be examined by discriminating the branch automatically on a basis of accessed address data obtained by operating the system to be examined. CONSTITUTION:Before analysis of the program, a computer system 1 to be examined is operated to store addresses of branch instructions and next accessed address data in a history memory 23. A CPU11 analyzes the program on a basis of this data; and when the address of the next record in the history memory and the next instruction address of the branch instruction address coincide with each other, next flags and branch flags are set to ''1'' altogether. If both flags are set to ''1'', the passage of all paths is discriminated. The discrimination result is displayed on a display 14 by the indication of a key input device 13, and information of C1 coverage can be gathered directly. C1 coverage means that it is checked whether the control passes all paths of the program to be examined or not. |
