A Framework for Semantics of UML Sequence Diagrams in PVS

Sematics of UML Sequence Diagrams in PVS

In this paper, we present formal semantics of UML (Unified Modeling Language) sequence diagrams using the PVS (Prototype Verification System) [8] as an underlying semantic foundation. We give a formal definition of a trace-based semantics [5] of UML sequence diagrams; i.e. a sequence diagram is interpreted as a set of traces of events that may occur in the realization of the interaction specifi...

Semantics of UML Statecharts in PVS

In this paper, we propose formal semantic definition for UML statecharts in the PVS specification language. Based on the semantic definitions, we develop a general framework for translating UML statechart diagrams into PVS specifications, and show how the resulting specification can be model-checked by using the PVS toolkits. This work is a part of a long-term vision to explore how the PVS form...

An Outline of PVS Semantics for UML Statecharts

The current UML standard provides deenitions for the semantics of its components. These deenitions focus mainly on the static structure of UML, but they don't include an execution semantics. These deenitions include several "semantic variation points" leaving out the door open for multiple interpretations of the concepts involved. This situation can be handled by formalizing the semantic concep...

Towards a formalization of UML Class Structure in PVS

The Unified Modeling Language (UML) is a language for specifying, visualizing and documenting object-oriented systems, and serves as a standard OO modeling notation. As the semantics of UML constructs is given informally in natural language, it is, for example, difficult to formally reason about correctness of a system design. Formal methods provide a rigor that is lacking in most of OO modelin...
