Abstract
A simulation device and method to simulate the electric current flowing in electronic devices using the moment method, and to execute accurate simulation processing when the electronic device has an amplifier. An allocating device allocates defining dipoles to the input terminal and output terminal of an amplifier of an electronic device for the purpose of deriving the electric current flowing in the element. A creating device creates a simultaneous equation of the moment method having a form such that the amplifier input impedance is inserted into the input terminal dipole allocated by the allocating device, and the amplifier output impedance, or its inverse, and a dependent energy source responding to the amplification characteristics of the amplifier are inserted into the output terminal dipole allocated by the allocating device. A solving device solves the simultaneous equation of the moment method created by creating device.
