Abstract

PURPOSE:To easily obtain the desired information by securing such a constitution where an analyzing result extracting means groups all analyzing results of a circuit obtained by a circuit analyzing means based on the given conditions related to the connection and read out of a control information memory means and then extracts only the most important analyzing result. CONSTITUTION:A control information memory means 3 stores the given conditions related to the connection between each terminal of a circuit and each connection line as well as the importance deciding conditions of the circuit analyzing results. Then an analyzing result extracting means 4 groups all analyzing results of the circuit obtained by a circuit analyzing means 2 based on the given conditions of the connection read out of the means 3. At the same time, only the most important analyzing result is extracted for each group of analyzing results which are grouped after the importance deciding conditions of the circuit analyzing results. An analyzing result display means 5 displays the extracted most important analyzing result. Thus the desired information is easily obtained without checking all circuit analyzing results.
