Claim 0:
1. A simulation method of a multilayer capacitor for three-dimensional electromagnetic simulation, the method comprising:
providing a simulation model of a multilayer inductor between a first input/output port and a second input/output port, and providing a simulation model of the multilayer capacitor between a third input/output port and a fourth input/output port; and
simulating a characteristic relating to crosstalk between the first input/output port and the fourth input/output port or between the third input/output port and the second input/output port by inputting a frequency sweep signal to the first input/output port or the third input/output port; wherein
the simulation model of the multilayer capacitor includes a plate-shaped first internal electrode model between the third input/output port and the fourth input/output port, and a plate-shaped second internal electrode model between the third input/output port and the fourth input/output port;
a capacitance, an equivalent series resistance, and an equivalent series inductance obtained from an actually measured value of an impedance characteristic of the multilayer capacitor are set for the first internal electrode model and the second internal electrode model;
the first internal electrode model faces two side surfaces opposed in a width direction of the multilayer capacitor;
the second internal electrode model faces two main surfaces opposed in a height direction intersecting the width direction of the multilayer capacitor; and
the providing further includes providing the simulation model of the multilayer capacitor adjacent to the simulation model of the multilayer inductor, and the first internal electrode model or the second internal electrode model intersects a magnetic field from the simulation model of the multilayer inductor.
