Abstract
A design assisting system is constructed as a CAD (computer-aided design) system for assisting in designing printed-circuit boards or other electronic devices. The system makes it possible to design layouts for reducing an unwanted electromagnetic radiation due to a common-mode current. The system has a first tool for converting at least a set of an electronic device, an interconnection, and a ground plane from layout information of a circuit board into a model for analyzing an electromagnetic field, a second tool for specifying a frequency and calculating a magnetic field intensity distribution near the ground plane using the model, and a third tool for superposing the calculated magnetic field intensity distribution and the position of the interconnection, determining whether a position where a magnetic field or a current is strong and the position of the interconnection are close to each other or not, and outputting a determined result.
