PURPOSE:To stabilize the extraction time of a terminal group which constitutes a conducting circuit by extracting the conducting circuit from an origin element number and destination element number group inputted through a keyboard input means. CONSTITUTION:Wiring information is written on an origin terminal-destination terminal table 33 in increasing order. Then, wiring information before circuit decision is retrieved in the table 33, its origin terminal 41 and destination terminal 42 are written on the conducting circuit constituent terminal group table 34, and the wiring information is retrieved with the circuit is decided. Then the terminal name 44 of a terminal before circuit retrieval is extracted from the table 34 and the same origin terminal and destination terminal matching with the terminal name 44 are retrieved in the table 33. This retrieval is carried on until the origin terminal becomes larger than the terminal name 44. In the middle of the retrieval, when the terminals 41 and 42 having the same contents as the terminal name 44 are detected, a terminal having contents different from the terminal name 44 is entered into the table 34 and its wiring information is retrieved until the circuit is decided. This operation is performed repeatedly until all terminals in the table 34 are retrieved. Then this operation is repeated until all pieces of wiring information in the table 33 are decided. |
