Abstract

Modern cars require powerful multi- and many-core hardware platforms to fulfill the demands of upcoming computationally intensive advanced driver assistance systems. This leads to a distributed hardware/software architecture that poses an unbearable system complexity to designers. Additionally, the strict requirements of new functional safety standards make it extremely difficult to rapidly and comprehensively close the development-evaluation-debug cycle. To overcome these complications, virtual platform technology is a promising approach that provides full hardware/software visibility, controllability and adequate simulation speed at electronic system level. However, for highly heterogeneous systems, such as modern cars, this technology lacks the capability to capture and integrate interactions of multiple subsystems beyond the hardware/software domain. To bridge this gap, this work presents multiple methods to facilitate the integration of virtual platforms into complex heterogeneous multi-domain vehicular simulation systems via the Functional Mock-Up Interface (FMI), the de facto co-simulation standard for automotive. The presented approaches significantly increase the depth of functional safety testing, as holistic car simulation covers cross-domain interactions of its subsystems.
