Abstract:
1. An analysis apparatus comprising: a reception unit for receiving information representing a property of a material forming a circuit board and wiring, information representing an arrangement of said material, information representing electric characteristics of a plurality of elements, and information representing said plurality of elements and said wiring linking said plurality of elements to each other; a first calculation unit for calculating a magnitude of an electric field and a magnitude of a magnetic field at a plurality of predetermined points of time for each of said circuit board and said wiring using a magnitude of an electric field and a magnitude of a magnetic field resulting from current and voltage in said element, said information representing a property, and said information representing an arrangement; a conversion unit for mutually converting a magnitude of an electric field and a magnitude of a magnetic field, and a current value and a voltage value; a division unit for dividing said information representing wiring linking a plurality of elements to each other into multiple pieces of element definition information representing wiring to which each said element is linked; a second calculation unit for calculating a current value and a voltage value at said plurality of predetermined points of time for an element represented by each of multiple pieces of element definition information divided by said division unit, using a current value and a voltage value converted by said conversion unit from a magnitude of an electric field and a magnitude of a magnetic field calculated by said first calculation unit, multiple pieces of element definition information divided by said division unit, and said information representing electric characteristics; and an output unit for outputting (i) the magnitude of the electric field and the magnitude of the magnetic field calculated by the first calculation unit, (ii) the current value and the voltage value calculated by the second calculation unit, or (iii) the magnitude of the electric field and the magnitude of the magnetic field calculated by the first calculation unit as well as the current value and the voltage value calculated by the second calculation unit.
