Abstract
In a printed circuit board design support apparatus for supporting design of a printed circuit board by calculating a radiation amount of electromagnetic radiation caused by an interconnection on the basis of design information related to each of the printed circuit board having a ground plane, interconnections formed on the printed circuit board, and components to be mounted on the printed circuit board, an arithmetic unit calculates a common mode (CM) radiation amount of the interconnection on the basis of a CM radiation amount ratio that indicates a ratio of a common mode (CM) radiation amount of electromagnetic radiation caused by the ground plane in correspondence with the interconnection to a differential mode (DM) radiation amount of electromagnetic radiation caused by the interconnection. A printed circuit board design support method and program are also disclosed.
