Simulation-based validation and verification (V&V) of the overall system safety and functionality is crucially important to reduce development times while maintaining the product quality. Dealing with such complex problems usually requires several teams collaborate during the development process. Standardized interfaces and data formats like FMI, SSP are key enablers for such collaborative development environments. The authors developed a Transmission Control Unit (TCU) proof-of-concept to evaluate how SSP and FMI standards can facilitate such collaboration development tasks. For example we analyzed: (1) sharing models with an agreed architecture, while applying IP protection, (2) performing parameter variations for testing and calibration of a component; (3) converting a given simulation architecture and interface definition to an SSP architecture in an automated and incrementally updatetable manner. Very recently, we started to extend this concept with virtual ECU implementations, utilizing the features of FMI 3.0 and FMI layered standards such as FMI-LS-XCP and FMI-LS-BUS.
