Printed circuit board design system and printed circuit board design method

摘要

The printed board design system designs a board configuration of a printed board on which an IC and passive components are mounted and a cable is connected. The printed circuit board design system includes an input unit, an EMI characteristic deriving unit that derives EMI characteristics from design information of the printed circuit board that the input unit has received input, a determination criterion storage unit that stores EMI allowable conditions, When it is determined that the EMI characteristic is compared with the EMI permissible condition to determine whether the EMI characteristic satisfies the EMI permissible condition, and the EMI permissible condition is not satisfied, A board configuration changing unit that changes a configuration inside the printed circuit board and sets design information of the printed circuit board having the changed structure to design information for deriving an EMI characteristic by the EMI characteristic deriving unit; And an output unit that outputs a configuration of a printed circuit board that satisfies the EMI allowable condition when it is determined that the EMI allowable condition is satisfied.
