PREEvision 10.20: The RFLP tool for systems engineering

Press Release, 14 August 2025

PREEvision 10.20 consistently supports the RFLP methodology. From requirements (R) to the functional (F) and logical (L) views and on to the physical (P) view of hardware and software, PREEvision covers all aspects of cyber-physical system development in a single tool. A simple user interface guides users step by step through the entire process.

The requirements view (R) allows you to develop and easily reference stakeholder and system requirements with each other. Further refinement is supported by detailed software and hardware requirements. Thus, a common target image of the system can be developed, coordinated, and communicated to all project partners. Simple links enable consistent traceability and maximum transparency.

For the functional perspective (F), which includes the description of the system’s functions and data and control flow, PREEvision 10.20 offers a dedicated activity diagram to describe behavior. Logical functions or building blocks can be used to model the system’s structure from a logical perspective (L). The sequence diagram has been improved and expanded for behavioral descriptions.

PREEvision’s proven tools are available for describing the physical system (P), which consists of hardware and software. The architecture and detailed design can be developed without switching tools. The development of the necessary tests has also been simplified.

Thus, PREEvision offers a complete, integrated systems engineering solution. Users can easily establish traceability between requirements, tests, and technical development artifacts at any point in the model with drag-and-drop functionality. PREEvision 10.20 introduces suspect links that display if the related requirements have changed at each test. This ensures transparency and enables consistency checks across the entire model.

Thanks to its end-to-end traceability, PREEvision is ideal for implementing methods and industry standards, such as RFLP, ASPICE 4, and ISO 26262.

PREEvision 10.20 comes with several example models to quickly introduce users to the new functionalities. These examples make it easy for users to understand the RFLP methodology.

Additionally, PREEvision 10.20 offers numerous improvements and an expanded data model for software design, diagnostics, and communication. For example: SOME/IP interface deployments can be exported via the Franca interface, and modeling IPC bindings for in-process communication in HPCs has been simplified.

Furthermore, PREEvision 10.20 enhances the server API and product line engineering. The release notes provide an overview of all improvements. The new release is available immediately. Updating from version 10.5 or any subsequent release to version 10.20 is straightforward because no data migration is necessary.
