OEMs aim for virtualization of the entire car and its environment for full system validation of their embedded system software stacks prior to deployment on hardware-in-the loop testing platforms and subsequent field testing. Depending on the individual validation target, Virtual ECUs modelled at different levels of abstraction are used in these co-simulation environments. It is thus desired to seamlessly switch between the abstraction levels and this needs to be supported by distributed co-simulation platform. The introduction of adaptive AUTOSAR as a POSIX compliant embedded OS further increases the heterogeneity of the simulation models. Availability of certain virtual models and tools in the automotive software testing eco-system may be limited to certain OS-platforms. Specific hardware requirements may also be imposed by scenario simulators that often call for advanced GPUs for rendering of environment images. In this context we introduce our next generation parallel co-simulation backplane for distributed data-exchange and synchronization between virtual ECUs and environment simulations. This is the crucial component of our Platform for full system test & development of embedded vehicle software. It offers true multi-abstraction, -host, -host-architecture, -host-os support. Differences in simulator performance are embraced and additional communication overhead is minimized. Our synchronization methods ensure deterministic simulation and maximize parallel execution.
