Return route search device, circuit design apparatus and circuit design program storage medium
摘要：
A return route search device includes a starting point/destination point setting section which accepts the setting of a starting point on a circuit from which a return current starts accompanied by a signal transmission on the circuit, and a setting of a destination point on the circuit to which the current flows. The return route search device further includes an easiness setting section which accepts a setting of easiness of conduction of the return current through each of portions on the circuit, and a return route search section which searches for a route when the return current flows from the starting point to the destination point on the basis of the easiness of conduction on the circuit.
摘要（中）：

返回路径搜索装置包括起始点/目的地点设定部分，其接收在电路上启动返回电流的起始点的设置，伴随着电路上的信号传输，以及电路上的目的地点的设置 电流流过。 返回路径搜索装置还包括容易设定部，其接受通过电路中的各部分的返回电流的导通的设定的设定部，以及返回路径搜索部，其在返回电流从起始时流动时搜索路线 基于电路上的传导容易度指向目的地点。
