摘要：
An approach for transforming UML statecharts into Projection Temporal Logic(PTL) formal models for system's simulation and verification is presented in this paper. UML Statechart is a graphic tool used to describe systems' behaviors, but it lacks formal semantics. PTL is a kind of temporal logic interpreted over discrete state sequences (intervals). With PTL, the formal semantics of UML Statecharts is defined. By transforming a UML statecharts into PTL model and describing properties with PTL, the system can be formally verified in the same logic frame and further simulated by Tempura an executable subset of PTL. A tool has been developed for automatically transforming UML statechart diagrams into PTL formal models which will facilitate system's simulation and verification.
