摘要:PROBLEM TO BE SOLVED: To provide an automatic ground guard wiring system capable of automatically preparing ground guard wiring. SOLUTION: This system is provided with a means for preparing ground guard wiring 17 so as to surround a signal line 15 in designing a printed wiring board 13 by using a printed wiring board design CAD system 1, and for designating at least one of the distance between the signal line 15 and the ground guard wiring 17 and the conductor width of the ground guard wiring 17 with respect to the signal line 15 to which the ground guard wiring 17 should be provided. Thus, it is possible to solve the problem that the signal line 15 and the ground guard wiring 17 are abnormally brought close to or brought into contact with each other to cause a short circuit. In addition, it is possible to sharply reduce the man-hours of design compared to the case that the pattern of the ground guard wiring 17 is prepared so that the wiring 17 is prevented from being brought into contact with the signal line 15 by comparing a circuit pattern displayed on a display means 3 of the CAD system 1 with a request document from a circuit designer.
