CIRCUIT BOARD DESIGN SUPPORT SYSTEM AND WIRING DESIGN SUPPORT PROGRAM

PROBLEM TO BE SOLVED: To provide a circuit board design support system and a wiring design support program, efficiently realizing wiring design work for a circuit board executing wiring between IC chips or of a semiconductor circuit requiring the transmission line circuit wiring of a structure allowing high-speed transmission. SOLUTION: This circuit board design support system for wiring a signal line between a driver and a receiver on a conductor layer, forming pair wiring of the same coordinate position and actually same wire width on a conductor layer adjacent through an insulation layer, and designing a wiring pattern of a stacked pair wiring structure has: a condition setting means 10 having at least one means of a wiring kind setting means, an automatic production decision means and a wiring position setting means; a signal line input means 20 for inputting signal line data to the conductor layer; and a data production means 30 producing pattern data based on the signal line data inputted in the signal line input means 20 on the conductor layer adjacent to the signal line.
