Abstract
A computer converts dimensions of design patterns of components of the transistors configuring the semiconductor circuit or component parameters extracted from in-design physical characteristics of the transistors into simulation parameters inputted to the simulator, organize the plurality of transistors included in the semiconductor circuit into a plurality of groups, selects any selection groups from the plurality of groups, sets fixed parameter values as component parameters of the non-selected groups other than the selection groups in the plurality of groups, sets the combinations of the component parameters in the selection groups, acquires circuit characteristics with respect to each combination of the component parameters, selects a group as a next selection group different from the selected groups, and repeatedly executing the setting the fixed parameter values through the selects a group as a next selection group different.
