Abstract:
1. A design system equipped with capability to analyze design data for a circuit board having circuit elements and wiring placcd thereon, comprising: a storing section that stores the design data, including structure data representing a structure of the circuit elements and wiring placed on the circuit board, circuit data representing circuits built from the circuit elements and the wiring, and element data concerning the circuit elements; a selection section that selects a pair of circuit elements that are spaced apart from each other and are subject to interference analysis among the circuit elements placed on the circuit board represented by the structure data; a substitution section that acquires element data concerning the circuit elements selected by the selection section from the design data and generates, based on the element data, equivalent circuit data representing electromagnetic coupling within the space between the pair of circuit elements using an equivalent circuit; and an analysis section that calculates an amount of interference within the pair of circuit elements by analyzing data obtained by combining the equivalent circuit data with the circuit data.
