PREEvisionModel-Based E/E Development
PREEvision – This isModel-Based E/E Engineering
Electrification, autonomous driving, connectivity inside and outside the vehicle: The onboard electronic network has become the brain of today’s cars.
The ever-increasing sharing of data within vehicles and to systems outside of the vehicle raises the complexity and makes the development of electric and electronic systems in vehicles, the so-called E/E development, more and more challenging.
PREEvision is a model-based development environment, that faces these challenges, and supports the entire E/E development – from architecture design all the way through to the final wiring harness.
- Design, management and documentation of complete E/E systems in one tool
- Integrated traceability
- Graphical modeling in diagrams
- Full support of AUTOSAR methodology
- Design of safety-relevant systems acc. to ISO 26262
- Variant management and product line engineering
- Complete development from architecture to wiring harness based on one source
Model-Driven E/E System Development
PREEvision is the premier tool for model-based development of distributed, embedded systems in the automotive industry and related fields. This engineering environment supports the entire technical development process in a single integrated application.
It offers comprehensive functions for both classic and service-oriented architecture development and all aspects of an E/E system including requirements engineering, AUTOSAR system, software and communication design as well as wiring harness development. The integrated and model-based approach helps complex tasks to remain straightforward and controllable.
PREEvision supports the tried-and-tested system engineering principles of abstraction, decomposition and reuse and can serve as engineering backbone: it enables parallel work on a common database from multiple locations.
Highlights Version 10.0
New Features and Most Important Changes
- Signal-Driven Communication Design
You can now develop a communication design by simply defining transmit or receive relations between signals and ECUs or NM nodes. The signal router and further synthesis functions help to complete the design. A software or logical design to motivate the communication is not needed.
- Service-to-Signal Mapping
The modeling of combined systems with software components using AUTOSAR Adaptive and AUTOSAR Classic is further enhanced. The service-to-signal mapping bridges the communication based on service interfaces in AUTOSAR Adaptive and the signal-based communication on the Classic platform.
PREEvision offers a new modeling layer for diagnostic data. Here, the objects for diagnostic specifications can be defined including diagnostic identifiers (DIDs), I/O controls, routines, etc.
- System Monitoring
You can now determine the state of the PREEvision system at any time. The complete infrastructure from client through network to server and database is continuously monitored.
How to Design Entire Automotive E/E Systems
PREEvision's data model with dedicated abstraction layers
The PREEvision E/E data model is the foundation for a consistent model-based method of working from the requirements engineering to all the implementation steps. All the aspects of an automotive E/E architecture are modeled in an integrated approach. From the requirements and the architecture design all the way through to the final wiring harness.
In adopting this approach, PREEvision follows the three proven systems engineering principles of abstraction, decomposition and reuse and supports the modeling of product lines and product variants with various model layers.
Additionally PREEvision provides an integrated process and team support including test engineering and management, support for functional safety as well as tools to manage changes, defects and releases.
