摘要： An object is to simplify a power supply noise analysis model of a circuit board. CAD data of the circuit board is obtained from a CAD apparatus, and overlapping power supply islands among power supply islands existing in different layers of the circuit board are extracted as a power supply pair. Nodes are arranged in the extracted power supply pair, and the nodes of the power supply pair are projected on the power supply islands to which the power supply pair belongs. A mesh region which encloses each node is determined for each power supply island, and impedance (L, R, C) between nodes is calculated. Then, a power supply noise analysis model is created based on the impedance between nodes in each layer, and a capacitance between layers.

摘要： A selector calculates a difference between the number of write operations of a first storage medium and that of a second storage medium and takes the difference as a first difference. Further, the selector calculates a difference between the number of write operations of the first storage medium and that of a third storage medium after copying the data within the second storage medium to the third storage medium and takes the difference as a second difference. Then, the selector selects the second storage medium as a target of replacement with which the second difference is larger than the first difference. A setting changer copies the data stored in the second storage medium selected as a target of replacement to the third storage medium, and changes the setting of the second storage medium to a spare and the setting of the third storage medium to a data write destination.
