“…The most interesting ones are comparison of models and minimization of models with respect to simulations and bisimulations. Minimization has been used in our case study to extract most general properties with respect to an observation criterion, given by a set of observable events (see in [3,4]). …”

Abstract. We present the modeling and validation experiments performed with the IFx validation toolset and with the UML profile developed within the IST Omega project, on a representative space vehicle control system: a model of the Ariane-5 flight software obtained by manual reverse engineering. The goal of the study is to verify functional and scheduling-related requirements under different task architecture assumptions. The study is also a proof of concept for the UML-based validation technique proposed in IFx.

“…A number of basic requirements are identified from the PCEP specification and then described as properties in IF. Based on these properties, the validation and verification of the formal specification are carried out using the IF toolset [9].

Abstract. In this paper, we present the modeling, validation, and verification of an industrial protocol for constraint-based path computation, called PCEP. From the PCEP specification defined by IETF, we divide the functionalities of PCEP into two parts: application and protocol. The protocol part of PCEP is then described in the IF language which is based on communicating timed automata. A number of basic requirements are identified from the PCEP specification and then described as properties in the IF language. Based on these properties, the validation and verification of the formal specification are carried out using the IF toolset. Test cases are generated by using an automatic test generation tool, called TestGen-IF, which uses partial state space exploration guided by test purposes. As a result of the modeling, validation, and verification, some errors and ambiguities are found in the PCEP specification. Also a number of test cases are obtained which will be used for testing implementations.

“…We use the DRE Semantic Domain to verify distributed non-preemptive real-time scheduling of avionics applications built upon the Boeing Bold Stroke platform [6,7], which is component middleware developed using Real-time CORBA [8] that has been ap-plied in a variety of mission-critical avionics computing systems. This specification technique enables the use of a wide variety of modeling formalisms supported by analysis tools, such as Uppaal [9,10], Kronos [11], and the IF [12] toolset.…”

Verifying distributed real-time properties of embedded systems via graph transformations and model checking

Component middleware provides dependable and efficient platforms that support key functional, and quality of service (QoS) needs of distributed real-time embedded (DRE) systems. Component middleware, however, also introduces challenges for DRE system developers, such as evaluating the predictability of DRE system behavior, and choosing the right design alternatives before committing to a specific platform or platform configuration. Model-based technologies help address these issues by enabling design-time analysis, and providing the means to automate the development, deployment, configuration, and integration of component-based DRE systems. To this end, this paper applies model checking techniques to DRE design models using model transformations to verify key QoS properties of component-based DRE systems developed using Real-time CORBA. We introduce a formal semantic domain for a general class of DRE systems that enables the verification of distributed non-preemptive real-time scheduling. Our results show that model-based techniques enable design-time analysis of timed properties and can be applied to effectively predict, simulate, and verify the event-driven behavior of component-based DRE systems.
