In this paper, further steps for model based function development for early maturity improvement for networked in-vehicle functions have been outlined. Based on the current state, modeling of compounds of functions located on ECUs and modeling networked functions have been identified as the next steps. Thereafter derived requirements for modeling tools have been discussed. A simple case study has been presented which illustrates the basic concepts and builds the basis for the evaluation of the capability of SimEvents. SimEvents provides a very general approach for modeling communication systems. Nevertheless, the toolbox is quite powerful. Only a few blocks allow it to model a huge variety of problems from operating system modeling to communication modeling. The big advantage of SimEvents is that it allows the modeling and simulation of the functional behavior of both the functions and the communication system in one tool, without the need for model export, or tool-coupling. This prevents the user from handling multiple tools to achieve his goals. The intended uses-cases communication modeling could be realized by using the toolbox. However in applying the toolbox to automotive CAN applications, additional features could help to make modeling more convenient. Currently, only scalars can be applied as attributes. For detailed modeling application data elements to be sent via the CAN bus, Simulink busses should be allowed as attributes. Communication description matrices could be used as input information for configuration of the simulation model. SimEvents allows for the modeling of the temporal communication aspects of distributed functions quite well. Additionally, means for the modeling of common communication mechanisms of software components such as the client server mechanism of the AUTOSAR virtual functional bus have to be supported.
