- The design of advanced embedded control systems requires a systematic approach in handling their increasing complexity and in particular integration of the different aspects and parts of a product worked on by different experts. Several variants of model-based approaches are today advocated to facilitate systems integration. This paper describes a number of representative efforts that address multiple concerns or views including modeling languages such as AADL and EAST-ADL as well as model integration environments such as GeneralStore, ToolNet, and Fujaba. We present a characterization of the approaches and thereby highlight their commonalities and differences regarding basic integration mechanisms and engineering support. We conclude with a prospect for future work.

FAR EAST : Modeling an automotive software architecture using the EAST ADL
- 2004
-
Ingår i: Proc. 26th International Conference on Software Engineering.
-
Konferensbidrag (refereegranskat)abstract
- We present a case study where a concept vehicle is remodeled using a new systems modeling approach, the EAST ADL (Architecture Description Language). EAST ADL is a language for modeling and development of software based systems. The application domain is automotive software-based systems. The language has been developed within the project EAST-EEA by representatives of European automotive industries and academic research sites. EAST ADL supports modeling during all stages of development of vehicle functions; from function selection, through function specification, to implementation of a running system. The language further supports modeling of aspects orthogonal to software structure, such as requirements, behavior, validation, and verification. The FAR vehicle has been previously developed, using model based development. Within this paper we re-model the FAR vehicle using the EAST ADL. The new model ties together the various models, code and documentation in a consistent structure with clear relationships between entities.

Software Component Technologies for Heavy Vehicles
- 2005

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Control-systems for heavy vehicles have advanced from an area where Industrial Requirements on Component Technologies for Embedded Systemsmainly mechanic and hydraulic solutions were used, to a highly computerised domain using distributed embedded real-time computer systems. To cope with the increasing level of end-customer demands on advanced features and functions in future vehicle systems, sophisticated development techniques are needed. The development techniques must support software in numerous configurations and facilitate development of systems with requirements on advanced functionality, timeliness, and safety-criticality. In order to meet these requirements, we propose the use of component-based software engineering. However, the software component-technologies available on the market have not yet been generally accepted by the vehicular industry. In order to better understand why this is the case, we have conduced a survey - identifying the industrial requirements that are deemed decisive for introducing a component technology. We have used these requirements to evaluate a number of existing component technologies, and one of our conclusions is that none of the studied technologies is a perfect match for the industrial requirements. In addition, we have implemented and evaluated the novel component model SaveCCM, which has been designed for safety-critical automotive applications. Our evaluation indicates that SaveCCM is a promising technology which has the potential to fulfil the industrial requirements. However, tools are still immature and incomplete. In the final part of this work, we propose the use of monitored software components, as a general approach for engineering of embedded systems. In our approach, a component's execution is continuously monitored and experience regarding the behaviour is accumulated. As more and more experience is collected the confidence in the component grows.
