PURPOSE: A probabilistic answer of high resolution is obtained and the time required for completing estimation of the device performance is shortened by processing statistically a pair of equations showing a data set corresponding to the answer of a model against the input data showing a device parameter and performing the probabilistic display of the device performance. CONSTITUTION: The input data (20) showing a device parameter are given to an experiment design (model) (22) which is produced by the computer software. The data (20) are not equal to the single input value and equal to the distribution of input value. The model (22) includes an expected range of input value, and the result of the model (22) is equal to a data set that describes a multidimensional surface showing the device performance and is expressed by a series of equations (24) which are shown as f(x). The equations (24) are arrayed on a spread sheet and accordingly a model (25) is set based on these equations (24). Then a probabilistic answer (28) including the distribution and statistic concerning each output value is obtained by means of a statistic routine (e.g. Monte Carlo analysis) (26).
