Abstract
The design system, which is equipped with capability to analyze circuit board design data, comprises a storing section for recording design data, including structure data, circuit data, and element data; a selection section for selecting a pair of circuit elements subject to interference analysis among circuit elements placed on a circuit board, represented by the structure data; a substitution section for acquiring element data concerning circuit elements selected by the selection section from the design data and, based on element data, generating equivalent circuit data representing electromagnetic coupling within the pair of circuit elements with the help of an equivalent circuit; and an analysis section for calculating an amount of interference within the pair of circuit elements by analyzing data produced by combining the equivalent circuit data with the circuit data.
