An established technique for this purpose is the decomposition of the system into smaller subsystems with well-defined, stable interfaces among them. In this paper, we propose a design method for the development of distributed real-time systems that are intended for safety-critical applications. The method is devised for the Time-Triggered Architecture, which constitutes such a real-time system. For the purpose of decomposition, we introduce a special type of interface, the so-called temporal firewall. In the Time-Triggered Architecture, there are three interfaces of this type-the Communication Network Interface, the Controlled Object Interface and the Gateway Interface-which partition the real-time system into autonomous subsystems. The design method clearly separates system and subsystem issues and focuses on the definition of the three interfaces between the subsystems. The feasibility and relevance of our design method is demonstrated by means of a small example from the automotive industry.","PeriodicalId":211905,"journal":{"name":"Proceedings 2nd IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'99) (Cat.

This is partly due to the fact that OO programming has been considered too expensive in terms of computational resources, but also because there are elements in the application functions for which OO methods do not give sufficient support. Nevertheless, OO techniques provide many advantages, and we discuss how they can be used for automotive real time control applications. The suggested approach is holistic in the following respects: it treats functionality on the vehicle level rather than on individual control units; it includes both the embedded system and its environment; and it considers both hardware and software.","PeriodicalId":211905,"journal":{"name":"Proceedings 2nd IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'99) (Cat.

The paper describes a software toolbox called ODYMOT that integrates a number of approaches to the problem of behavior modeling. In order to achieve design flexibility, a two-layer object design architecture is used that blends together object oriented design concepts with those of high level Petri nets. The Petri net representation creates an additional access layer of object architecture, providing meta level object control with the sequencing of method execution. This modeling approach allows one, both mathematically and pragmatically, to achieve a more precise and flexible description and implementation of real time and distributed models.","PeriodicalId":211905,"journal":{"name":"Proceedings 2nd IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'99) (Cat.

The system consists of a set of integrated tools for modeling, simulation, implementation, instrumentation, monitoring, and visualization that all work on the same OO system model. As all steps of creating a running implementation with visualized monitoring output from the design model are automatic, the environment encourages an iterative approach to the design of complex real-time control applications. This complete environment has been accomplished by integrating the SIMOO-RT modeling, simulation and implementation environment, developed at the Federal University of Rio Grande do Sul, with the Jewel++ object-oriented instrumentation and monitoring tool from GMD, St. Augustin, Germany. The work has been done in the context of the ADOORATA project (A Distributed Object-Oriented Architecture for Real-Time Automation), a Brazilian-German cooperation.","PeriodicalId":211905,"journal":{"name":"Proceedings 2nd IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'99) (Cat.

A protocol is a formal specification of potentially complex reusable pattern of inter-object behavior. To make it reusable, a protocol is defined independently of any specific object classes or instances. Even though they are defined independently of individual classes, we demonstrate how, using the notion of two-way interfaces called ports, protocols can be formally bound to structures of collaborating objects. This gives us a framework in which it is possible to formally verify if a particular combination of objects can indeed achieve the desired inter-object behavior. A further advantage is that programs with protocol specifications are more understandable and more maintainable than traditional object oriented programs since the required high level behavior is explicit. We describe both protocols and ports using the base concepts of the recent Unified Modeling Language (UML) standard.","PeriodicalId":211905,"journal":{"name":"Proceedings 2nd IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'99) (Cat.
