Abstract

The invention discloses a conversion tool and method from a model B to a timed automaton network. The tool includes an Event-B metamodel, a time automaton network metamodel, an EventB2NTA model transformation engine and an EventB2NTA model transformation configuration module. The method includes: combining and storing the Context model of the buc format of the Event-B and the Machine model of thebum format into an Event-B model of the xmi format; and converting the preprocessed Event-B model of the xmi format into the time automaton network model of the xmi format; storing the time automatonnetwork model in the xmi format as an xml format recognizable by the time automaton network tool UPPAAL, and then adding the corresponding time attribute according to the user's requirements to complete the modeling. The tool can be integrated into the Eclipse platform, and combines the advantages of the gradual refinement of the Event-B model with the explicit characterization of the time characteristics of the time automaton network model.

Description

technical field [0001] The invention relates to the technical field of computer software engineering, in particular to a tool and method for converting a complex software system Event-B model to a time automaton network. Background technique [0002] Early software modeling and design can reduce the development difficulty of complex software systems, such as complex military information systems and cyber-physical fusion systems (CPS), and improve system development efficiency. Among them, the Event-B model is a formal method for system-level modeling and analysis, which has a strict mathematical foundation, and Event-B can model complex systems in a "step by step refinement" manner. Modelers You can start with an abstract requirement specification, gradually iteratively introduce more implementation details, and finally complete the system modeling. Due to the feature of gradual refinement, using Event-B to model complex software systems can significantly reduce the difficu...
