DISPERSION SIMULATION SYSTEM, AND DISPERSION DETERMINING MODEL METHOD, APPARATUS AND PROGRAM

摘要

A dispersion simulation system is provided to carry out a simulation efficiently in consideration of dispersion in detail. The simulation system comprises a dispersion analyzing unit (100) for acquiring statistically analytic results in dispersion of characteristics with respect to a plurality of subject devices, a model analyzing unit (200) for acquiring analytic results showing how the characteristics respond to fluctuations of parameters with respect to simulation models to simulate the subject devices, a fitting execution unit (300) for comparing the results acquired by the dispersion analytic unit (100) with those acquired by the model analyzing unit (200) and determining how to disperse the parameters in order to reproduce the dispersion of the subject devices in accordance with models, and a result output unit (500) for outputting information of how to disperse of the parameters determined by the fitting execution unit (300). A simulation-reverse matrix of a response matrix is multiplied by a matrix composed of primary-component vectors and an arbitrary unitary matrix to determine a transformation matrix.
