What is model-based systems and software engineering?

Modeling equips your teams with fundamental capabilities that help address design and development challenges.

Describing and understanding the system under development becomes much easier thanks to graphical notation (SysML/UML), and a model does not require extensive additional documentation. Furthermore, the models can be fed into subsequent engineering activities in an automated process, avoiding error-prone manual rework or media breaks.

This reduces the risk of misunderstandings and avoids errors at hand-over from design to development.

Why you need a SysML/UML tool for modeling systems and software

A powerful tool environment for model-driven engineering allows your engineers to focus on what they do best: developing smart solutions that meet expectations and drive sustainable business.

How does it work? Such a SysML/UML tool environment relieves engineers of tedious secondary tasks, such as explaining algorithms and interfaces, complying with programming, domain or security guidelines, or creating and maintaining documentation. All of this is made easier with SodiusWillert offerings for model-based development of systems and software.

These tools provide your experts with the SysML/UML environment they need to create a model of the system under development that meets the requirements. Our engineering tools take care of managing the data, checking the interfaces, transforming the models if necessary, complying with standards and much more.

Increased product quality

SodiusWillert SysML/UML modeling tools offer market-leading capabilities to help you deliver high-quality products. Features include model-level simulation, automatic generation of efficient source code, support for reverse engineering and roundtrip engineering, support for team collaboration, and more.

Maintain clarity and transparency

Develop embedded software with no trade-offs to accommodate the limited language scope of C or C++ and without including RTOS-specific elements in your model. SodiusWillert tool bundles automatically include the required functions and adapters and generate code with only minimal overhead in terms of memory, runtime, and efficiency.

Reduced time-to-market

Modeling tools by SodiusWillert let you monitor and verify the behavior of your SysML/UML model early when errors can be fixed faster. Simulate execution within the modeling tool environment to evaluate functions, dependencies, interfaces, etc. Find and eliminate errors in real-time behavior by debugging your UML model on the target system.

Increased engineering efficiency through standards

SodiusWillert modeling tools come with SysML and AUTOSAR standard support. Leverage SysML for increased efficiency of your systems engineering projects. Implementation of solutions for AUTOSAR becomes easier, and project runtime is reduced thanks to AUTOSAR architecture elements already being included -- no need for tedious specification up front.

Extend the benefits of modeling to small embedded systems

Take advantage of UML modeling for software running on small embedded systems with limited resources, such as a smart "keyless go" car key. SodiusWillert modeling tool bundles include a miniature RTOS with basic runtime environment functions. These are included with one click during code generation, and the result is an executable that runs completely independently.
