Abstract
A checking unit includes a power net extractor for extracting a power net with power attribution, which is segmented by a power-decoupling element, with reference to circuit design data of a printed wiring board; a parts number extractor for extracting a parts number of an integrated circuit connected to the extracted power net; a parts headcount calculator for calculating a headcount of the extracted parts; a judging unit for comparing the extracted parts headcount with a predetermined reference value; and a representing unit for representing a name of the power net and the parts number of the integrated circuit as an unprocessed location of power decoupling when the headcount is larger than the reference value, thereby inspecting quickly whether a power supply in use, shared by each of the integrated circuits, is decoupled at higher frequencies by the power-decoupling element.
