An approach to refinement checking of SysML requirements
2011
ETFA2011
Preserved Fulltext
System engineering modeling language SysML is widely used in order to manage increasing complexity of embedded systems. ...
This work shows efforts towards integrating embedded systems modeling with verification measures, namely, with refinement checking (checking whether a system description is really an implementation of ...
Finally, the refinement verification model consists of two corrected CSP# models corresponding to the original FSMs and an assertion of type "modelA refines model B in trace semantics". ...

We describe the difficulties in translating 'run to completion' semantics into Event-B refinements and suggest a solution. We outline how safety and liveness properties could be verified. ...
Statechart notations with 'run to completion' semantics, are popular with engineers for designing controllers that respond to events in the environment with a sequence of state transitions. ...
Here we make use of UML-B's statemachine translation but provide a completely different semantic by generating a behaviour into the underlying Event-B events that are linked to the generated UML-B transitions ...

To relate these abstractions, through the execution trajectories of corresponding models, formal semantics for both kinds of models and a set of inference rules are defined. ...
In the development of embedded software, modeling languages used within or across development phases e.g., requirements, specification, design, etc are based on different paradigms and an approach for ...
Methodology Description In Section 2, we have described the syntax and semantics of two models used in the development of embedded system software: the event-based model of UML statemachines, and the time-triggered ...

UML-based Approach to Specify Secured, Fine-grained Concurrent Access to Shared Resources

UML protocol statemachine is used to define the access protocol for shared resources and UML activity is used to specify the behavior of methods implementing plausibly concurrent operations. ...
The approach is largely inspired from the language constructs of CDL*. A light-weight extension of UML 2.0 meta-model is proposed for the required constructs and semantics. ...
Where as many of the related works in UML [5, 10] are centered around refining the active object semantics, our work aims at refining the semantics of passive object to model a shared resource, a central ...

Since the UML standard only contains an informal description on how to execute such statemachines mathematically precise semantic frameworks are required for an automated analysis. ...

In Event-B, refinement is used to relate system models at different abstraction levels. ...
We now provide a more complete presentation of the technique of refinement in UML-B including a formalisation of the refinement rules and a definition of the extensions to the abstract syntax of UML-B ...
Semantics of UML-B The semantics of UML-B models are given by the generated Event B model and Event-B semantics are defined by the corresponding proof obligations. ...
