Abstract
A coupling distance y of a plurality of securing elements for coupling two members to construct a casing for accommodating a circuit board having electric components mounted thereon inside space surrounded by a conductor extracted from design data, an overlapping width x of overlap sections provided to the two members for coupling the two members with the plurality of securing elements, the overlap sections contacting to each other, and a wavelength λ of electromagnetic noises generated from the electric components, are extracted. Then, a recommended coupling distance Y for the plurality of securing elements to attenuate the electromagnetic noises by a certain attenuation amount is calculated, based on the overlapping width x and the wavelength λ, and the coupling distance y is compared with the recommended coupling distance Y. Thereby, verifications of an electromagnetic noise countermeasure can be made reliably without relying on settings by a user.
