ABSTRACT:
A model parameter extracting apparatus comprises a range designation unit, a combination designation unit, a simulator, a calibrator, a determination unit and a range update unit. The range update unit comprises a detection unit, a new range designation unit 28 and a range shift unit. The detection unit detects a model parameter capable of providing the slightest difference between a target characteristic value and an actual value, as a quasi-optimum value. The new range designation unit designates a numerical range having a half length of that of the previous adjustment range with the quasi-optimum value set at a center, as a new adjustment range. If the quasi-optimum value is a value at one end of the adjustment range, the range shift unit shifts the adjustment range such that the quasi-optimum value is at the other end of the adjustment range while maintaining the length of the adjustment range. The apparatus realizes automation of the re-setting of a model parameter.
