In checking a model of software, there is an approach of transforming a source code of software into a checking code in order to reduce a cost required to describe the checking code by an input language of a model checker. Since a user may select only a single transformation method, there are problems in that an abstraction-level change is difficult, a rule modification cost for following up a design and a change of the source code is high, and a rule modification cost for checking using another checking tool is high. In the present invention, when the source code is transformed into the checking code, a unit that selects a plurality of transformation rules is provided to allow the user to easily change an abstraction level. Further, the plurality of transformation rules include a transformation rule of transforming the source code into an intermediate format, a transformation rule of abstracting the intermediate format, and a transformation rule of transforming the intermediate format into the checking code.
