Statistical Analysis of Resource Usage of Embedded Systems Modeled in EAST-ADL
2015 IEEE Computer Society Annual Symposium on VLSI
The growing complexity of modern automotive embedded systems requires new techniques for model-based design that take into consideration both software and hardware constraints, and enable verification at early stages of development. In this context, EAST-ADL has been developed as a domainspecific language dedicated to modeling functional-, software-, and hardware-architecture of automotive systems. This language offers convenient abstractions that support modeling of function, as well as
... t extra-functional properties, like timing and resource usage. These features make it a suitable framework for reasoning about the system's behavior. By providing formal semantics to the EAST-ADL language, as a network of priced timed automata, it becomes possible to reason about feasibility and worst-case resource consumption of the embedded components. In this paper, we show how to analyze such embedded systems modeled in EAST-ADL by using statistical model-checking. We report our experience from applying this approach to an industrial Brake-by-Wire system prototype.
