Abstract:
1. A system for checking decoupling of power supply in a printed wiring board, comprising: a power net extracting means for extracting a power net with power attribution, which is segmented by a power-decoupling element, with reference to circuit design data of the printed wiring board; a parts number extracting means for extracting a parts number of an integrated circuit which is connected to the extracted power net; a parts headcount calculating means for calculating a headcount of the integrated circuit which is connected to the extracted power net; a judging means for comparing the extracted parts headcount with a predetermined reference value; and a representing means 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 equal to or larger than the reference value.
