Abstract: A source code analysis unit identifies dependency strengths of one or more functions included in a source code. An influence analysis unit identifies one or more transfer functions that will each move to a different subsystem due to refactoring and identifies a dependency strength to be influenced by the refactoring, based on the dependency strengths that have been identified by the source code analysis unit with respect to the one or more transfer functions. A scale calculation unit calculates the scale of the refactoring, based on the dependency strength to be influenced, which has been identified by the influence analysis unit.

Abstract: In a requirement analysis apparatus, a connection analysis unit classifies a plurality of requirement items into groups based on connections between requirement items indicated in item connection information. A subsystem analysis unit extracts the number of subsystems that are reached by tracing the connections from each requirement item, based on the connections between the requirement items indicated in the item connection information and based on the connection between each requirement item indicated in the item connection information and each subsystem. A result display unit displays, for each requirement item of the plurality of requirement items, analysis result information which is set with an identifier identifying a group into which the requirement item has been classified, and the number of subsystems being reached by tracing the connections from the requirement item.

Abstract: A memory diagnosis apparatus to diagnose whether a fault occurs in a memory includes a diagnosis execution unit to divide the memory into a plurality of areas, select two or more base areas that are diagnostic targets from among the areas to carry out a memory diagnosis including a reading test and a writing test, and perform only the writing test in carrying out the memory diagnosis on a same base area for second or more times. The diagnosis execution unit is implemented by an arithmetic device that is a processing circuit that executes a memory diagnosis program stored in a storage device.
