PURPOSE:To grasp the quality of a system to be examined by deciding the branch on a basis of address data in a history memory, which is obtained when the system to be examined is executed, to gather directly C1 coverage information. CONSTITUTION:A computer system 1 is operated to store data in a history memory 26 while various conditions are so changed that the control passes all branched paths in a program range from a set address adr1 to a set address adr9. The program is analyzed in accordance with data in the history memory 26 by a CPU11. A memory 12 has a check point address table, and records in the history memory 26 are set there in order from the first record at the operation start time to perform prescribed processings; and if all next flags and branch flags are set to ''1'' as the result, it is discriminated that the control passes all preliminarily set paths, and the decided result is displayed on a display device 14. |
