Abstract
An interference analysis device can be provided, which analyzes interference between wirings of a circuit board with reduced load and for a short time period. The interference analysis device according to the present invention includes: a design data input part for inputting design data of the circuit board; a noise characteristics setting part that sets data representing electrical characteristics of noise for a wiring of the circuit board; a limit value setting part that sets an allowable limit value of noise received by a wiring; a selection part that selects a wiring group to be analyzed based on the noise characteristics data and the allowable limit value; an interference analysis part that calculates, concerning the selected wiring group, an amount of interference from a wiring giving the interference to a wiring receiving the interference; and a received noise level calculation part that calculates a noise level that the wiring receiving the interference will receive.
