DESIGN SUPPORT PROGRAM, RECORDING MEDIUM WITH THE PROGRAM RECORDED, DESIGN SUPPORT DEVICE AND DESIGN SUPPORT METHOD

PROBLEM TO BE SOLVED: To achieve the reduction of a workload and the shortening of a design period by automating wiring with wiring length satisfying circuit characteristics of specifications in a prescribed wiring region. SOLUTION: A design support device is configured to retrieve a wiring path connecting first and second terminals arranged in a prescribed wiring region and a patrol path which is not connected to the wiring path within the prescribed wiring region, to calculate wiring path length by uniting the wiring path length of the retrieved wiring path and the wiring path length of the patrol circuit, to decide whether or not the calculated wiring path length is equal to or more than the wiring path length satisfying the circuit characteristics of specifications, and to output the decided decision result. Thus, it is possible to decide the feasibility of the wiring path length satisfying the circuit characteristics of the specifications in the prescribed wiring region by using the longest wiring path candidate obtained by combining any wiring path between terminals whose retrieval is relatively easy and the patrol circuit instead of the longest wiring path between terminals which are difficult to retrieve.
