System function networks

Abstract

Embedded systems are often highly integrated into a network of systems. To increase synergies, reduce code redundancies, and to support reuse, the different systems in this network provide conceptual functions for use by other systems. This chapter deals with the challenges resulting from this type of networked approach and provides essential solution concepts for obtaining benefits from the creation and analysis of the model-based documentation of the functional design of such conceptual system function networks. In particular, this chapter explains: The documentation format of the functional design of networked embedded systems, consisting of static/structural function networks, the functional behavior, and the timely execution order Analysis methods to aid validation and verification, as well as an optimal partitioning and deployment of networked embedded systems Construction methods to integrate the consistent creation of the functional design into embedded systems' development processes.
