Circuit design apparatus, circuit design program, and capacitor energy amount calculation method

摘要

A circuit design apparatus includes a storage that stores a first capacitance of a capacitor associated with one or more usage conditions, and a controller that controls an amount of energy of the capacitor under a specified usage condition of the one or more usage conditions. The controller calculates a second capacitance under the specified usage condition based on a first relationship between the specified usage condition and the first capacitance, and calculates the amount of energy of the capacitor based on the calculated second capacitance.
