Methods, tools and standards for the analysis, evaluation and design of modern automotive architectures

Abstract

Automotive systems are increasingly distributed and complex. Reduced time-to-market, cost and safety concerns require advance validation of the integrated systems and its components, from the functional, timing, and reliability standpoints. In particular, function correctness and performance may depend on communication and computation delays imposed by the selected architecture platform. Hence, the need for methods and tools capable of predicting the system-level timing behaviour (latencies and jitter), resulting from the HW platform selection, the synchronization between tasks and messages, and also from the synchronization and queuing policies of the middleware and RTOS levels. In this paper, we review methods and tools for the evaluation of the function performance and its timing correctness by simulation or by worst case static analysis.

Performance evaluation of an automotive distributed architecture based on HPAV communication protocol using a transaction level modeling approach

“…Typical non-functional requirements under consideration in the automotive domain are timing constraints, power consumption, fault tolerance, and cost. In this context, model-based approaches have then recently received wide interest in the automotive domain to face related design complexity of distributed architectures [1]. Systematic approaches for early evaluation of nonfunctional properties are necessary to assist system designers in the development process and related efficiency concerns simulation speed and light modeling effort.…”
