Title:
POWER-SUPPLY DESIGN SYSTEM, POWER-SUPPLY DESIGN METHOD, AND PROGRAM FOR POWER-SUPPLY DESIGN
Document Type and Number:
WIPO Patent Application WO/2012/014597
Kind Code:
A1
Abstract:
Disclosed is a power-supply design system for designing a power-supply of an electronic device. The system is provided with an input device which inputs circuit information relating to a power supply of the electronic device; a current deviation calculation unit which calculates current deviation indicating current fluctuation of the electronic device on the basis of distribution information indicating distribution of the current fluctuation corresponding to the circuit information input by the input device and the circuit information; a target impedance calculation unit which calculates target impedance which is a target of the power supply indicated by the circuit information, on the basis of the current deviation calculated by the current deviation calculation unit and an allowable range of voltage fluctuation indicated by the circuit information; and an output device which outputs the target impedance calculated by the target impedance calculation unit.
