Abstract:
PURPOSE:To form an easily view connection diagram without an excessive cross and bending by controlling a connection sequence. CONSTITUTION:A net list input device 1 for reading the input and output information name of an element to be connected, an element arrangement information storing part 5 for reading and storing the arrangement information of the element, a connection processing part 4 for connecting two selected terminals and a connection control part 2 for feeding the two terminals to be connected to the connection processing part 4 from the inputted net list are provided. Herein, a connection sequence control part 6 is disposed to regulate the wiring sequence of the connecting terminals according to a rule whether a connecting line should be bent in an input side or in an output side. Accordingly, a part between the elements at near positions is connected by the shortest line. Thereby, the number of the crosses and the bendings of the wiring is reduced to more easily view a connection diagram.
