This paper outlines the modeling process in SysML (Systems Modeling Language) in context of MBSE (Model Based Software Engineering) as well as the MBD (Model-Based Design) in Simulink and we compare the models to get useful information into software. For this goal, we propose the use of a RM/SM tool and Simulink to model the system, do the system validations and finally to embed the generated code. MBSE is a methodology that can lead to reduced costs of OEM’s new products, since it can predict project errors and weaknesses. If the model is running as expected and providing good results, it is possible to go to a next step and implement the project in real applications, in order to observe the behavior of the new product, for example, by embedding software codes directly into hardware or building a new hardware. Due to the complexity of integration of new electrical and electronic systems, MBSE use is justified. For automotive systems, the development process is visualized through the V-Model, which leads to the right choice of components, the integration of the system and the project realization. The first step in V-Model handles the requirements management for the development, i.e., the requirements for a project will be collected in respect to the stakeholder’s point of view and system limitations. Then, the next steps consist of modeling the system based on its requirements, going through simulation, system validation, embedding, and finally testing in real applications. In this paper, the chosen modeling language is System Modeling Language (SysML) which is a general-purpose language and its aim is to standardize Modeling Design, by unifying diverse modeling languages used by engineers. This language also supports specification, analysis, design, verification, and validation of systems. Our approach in this work addresses the first steps of V-Model through SysML and MBD in Simulink. To achieve that, we use the commercial Requirement Management/System Modeling (RM/SM) tool 3SL CRADLE. 3SL CRADLE is used to collect requirements to provide a SysML design section as well. One of the objectives in using 3SL CRADLE is that it will be possible to analyze the transition from models in RM/SM tools to models for simulation, such as Simulink and offer a new possibility for OEM’s and suppliers to abstract formulated models into functional models.
