摘要
Disclosed is a variation simulation system including a variation analysis unit that acquires the results of statistical analysis of variations of characteristics of a plural number of target devices, a model analysis unit that acquires the results of analysis showing how the characteristics respond to variations of a parameter with respect to a model for simulation that simulates each target device, a fitting execution unit that collates the results obtained by the variation analysis unit to those obtained by the model analysis unit and determines the manner of variations of the parameter in order to reproduce the variations of each target device in accordance with the model, and a result output unit that outputs the information on the manner of variations of the parameter determined by the fitting execution unit. A transformation matrix is determined by multiplying a pseudo inverse matrix of a response matrix, a matrix made up of principal component vectors and an arbitrary unitary matrix.
