Many of today's advanced simulation tools are suitable for modeling specific systems, but they provide rather limited support for automated model building and management.The diverse tools available for modeling different components of a vehicle make it all the more challenging to comprehend their integration and interactions and analyze the complete system. In addition, the complexities and sizes of the models require a better use of computing resources, such as multicore or remote processing, to greatly reduce the simulation time.In this paper we describe how modern software techniques can support modeling and design activities, with the objective to create system models quickly by assembling them in a “plug-and-play” architecture. System models can be integrated, co-simulated, and reused regardless of the environment in which they are developed, and their simulation results can be consolidated for analysis into a single tool.As an example, we show that such management is achievable by integrating the functionalities of Argonne National Laboratory's Autonomie® and Kiastek's CosiMate® modeling tools. We demonstrate these functionalities through a Simulink vehicle model communicating with detailed submodels in their expert tools such as GT Power, AMESim, Saber, or CarSim on separate core.
