A design support system for designing a printed circuit board (20), comprising: a database (110) for storing layout data, noise source data of the printed circuit board (20), and calculation results; a data reading unit (120) for reading noise source data and local layout data of a local area (30) around the noise source (21, 205) from the database; a bypass devices introducing unit (124) for introducing current bypass devices (206) to the local area, and a calculation unit (130) for estimating the radiation effective forward wave power injected into assumed infinite power supply planes (210) of the printed circuit board from the noise source (21, 205) without and with current bypass devices (206), and for calculating their ratio. |
