Patent ID: 7823096

Claim:
An inductance analysis system for a multi-layered board including a power supply plane, said system comprising: analysis means for determining a potential distribution within a power supply plane by receiving information on a power supply plane in a state in which a beginning point of non-coupled current of return current associated with signal current is placed in a vicinity of a signal through-hole on said power supply plane, based on position information of said signal through-hole; and means for outputting the potential distribution within said power supply plane acquired, wherein said analysis means evaluates uncoupled inductance from said signal through-hole in said power supply plane to at least one of a power supply through-hole and a power supply via, and wherein said analysis means performs potential distribution analysis by analyzing two-dimensional heat diffusion in said power supply plane based on an assumption that a heat source has been placed at said beginning point of said non-coupled current.
