Model-Based Electric/Electronic Development
PREEvision 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.
Use Cases
Architecture Design
Design and assessmet of E/E architectures and fast evaluation of design alternatives. Multidimensional criteria for success can be freely defined, to develop a cost-optimized and robust E/E system.
Product Line Approach
Libraries and reuse of designs ensure efficiency in E/E development. Model series or individual vehicles can be derived from product lines using variant management.
Requirements Engineering
Seamless interworking of requirements with all development artifacts in the model extends PREEvision far beyond the functions of a classic requirements management tool.
AUTOSAR System Design
PREEvision is a component of the AUTOSAR tool chain from Vector and supports development of software and hardware architectures and communication design while incorporating many AUTOSAR concepts.
AUTOSAR Communication Design
PREEvision supports the AUTOSAR compliant communication design of all data elements transferred over the bus. Supported bus technologies are CAN, CAN FD, LIN, FlexRay and Ethernet.
Automotive Ethernet Design
Designing Ethernet networks and clusters including the corresponding communication. The model-based engineering environment also enables service-oriented architectures for embedded software systems.
Wiring Harness Design
For finding cost-optimized solutions, PREEvision supports wiring harness engineers with functions to evaluate different alternatives, to optimize designs and to define the final wiring harnesses in detail.
Process and Team Support
Functional Safety
To minimize the effort for development and maintenance of safety-related systems as per ISO 26262, PREEvision offers consistent development support for the entire safety process.
Testing
PREEvision supports test engineering, control of tests and management of accumulated test data across the entire E/E development process. This assures quality in all phases of an E/E project.
Multi-User Operation
Cross-location multi-user cooperation in E/E engineering projects: The PREEvision Collaboration Platform provides project and development teams with common access to required data without conflicts.
Changes, Defects and Releases
To steer E/E projects and to carry out changes during a project, PREEvision provides an integrated process support consisting of project, change and release management.
Highlights Version 9.0
AUTOSAR Adaptive
PREEvision 9.0 enables developers to model their E/E systems based on AUTOSAR Adaptive Platform. Whether engineers are designing service interfaces and applications, instantiating services or describing Ethernet communication via SOME/IP – this latest version provides comprehensive functions for these tasks. Data exchange is simplified by import and export functions for the Adaptive System Description and other work products of AUTOSAR for the new generation of high-performance Electronic Control Units.
AUTOSAR Variant Management
In addition to its well-established concepts for variant management, PREEvision now also allows variant management according to AUTOSAR. PREEvision supports AUTOSAR feature models, feature selections and feature maps to define the range of possible variants. With system constants, post-build variant criterions and variation points, predefined variants can be designed, activated and highlighted. Dedicated new diagrams are available for feature maps and variation points. Table based editors complete the specification of AUTOSAR variants.
State Chart and Class Diagrams
PREEvision 9.0 offers additional SysML and UML diagrams as modeling tools for functions, including those that will be deployed in service-oriented architectures. Designers can use the class diagram, for example, to model interfaces and data types.
The state chart diagram graphically depicts a system’s mode of operation. The two new diagrams supplement block, package and use case diagrams which have been included in previous PREEvision releases.
Review and Vote
To facilitate cooperation within the organization and with suppliers, PREEvision extends the process support with mechanisms to review and vote requirements and other model artifacts. Agreement projects can be set up by selecting model artifacts and resources that review the respective artifacts. A dedicated chat view allows discussions amongst the participants.
Additional New Features
- Support for AUTOSAR 4.3
- Server API that allows read access to model artifacts including their attributes, life cycle state, rich texts, files and diagrams
Layer Model
For the modeling of entire electric/electronic systems, from requirements to software and hardware architectures to the wiring harness, PREEvision provides a comprehensive 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 E/E architecture are modeled in an integrated approach.
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.
PREEvision Modelling Layers in Detail
To develop and manage customer features, use cases and requirements as the starting point and basis for development, PREEvision provides tables, rich text editors, and diagrams. Mappings (M) to concrete development artifacts ensure consistent traceability in every phase of development.
The systems functionality defined by requirements and customer features is broken down into logical functions and modeled in a function network (activity chains). Concrete technical implementation remains open here and is modeled on the layers for hardware or software.
Software components, ports and interfaces, as well as their connections to one another are specified and modeled in diagrams. A type-prototype-instance concept facilitates the reuse of development artifacts. The software architecture supports the AUTOSAR method including the corresponding import and export formats as well as either a function- or service-oriented approach. All implementation artifacts of software components can be managed in PREEvision including a Subversion management.
The hardware architecture comprises the definition of ECUs, sensors and actuators including their networking via bus systems (ring, star and line topologies), and the power supply and grounding concepts. In the electric circuit layer the electrical characteristics of the hardeware components and their connections are defined. The power supply and the internal electrical design of componets, such as fuses or resistors, are modeled here.
For the communication via bus system, signals, PDUs, frames and schedules can be specified. PREEvision supports all important bus technologies including CAN, CAN FD, LIN, FlexRay and Ethernet. An integrated signal router helps to optimize the architecture and automatically generates communication artifacts.
In the wiring harness layer the physical details (wires, cables and connectors) of the hardware network are defined. This includes details like connectors, pins and splices. The wiring harness diagram can be used as a basis for printouts of wiring harness drawings or the data exchange with development partners via KBL. Installation spaces for hardware components and installation routes for the wiring harness are defined in the vehicle geometry layer (or topology). 3D data can be imported for representation of defined installation spaces and locations.
PREEvision includes support for the complete test process from test engineering via the planning to the evaluation and analysis of test results.
PREEvision supports the management of changes and defects via tickets and provides a project and release management.
PREEvision supports the complete safety process according to ISO 26262 from item definition to safety case based on the existing model data.

Service-Oriented Architectures and Ethernet in Vehicles
Towards data centers on wheels with model-based methods
Service-oriented architectures (‘SOAs’) have been used for years in the IT industry to describe and structure distributed systems. However, service-oriented design is also becoming extremely significant in the automobile industry: how else can customers’ increasingly urgent demand to adapt the scope of functions of the automobile, similar to the possibilities of today’s smartphones, be met reliably? It is also necessary to handle additional requirements from model maintenance and to introduce technology such as autonomous driving and vehicle-to-X communication.
The development tool PREEvision supports the methodical, consistent design of a service-oriented architecture. The user is guided from the definition of the service interfaces, through specification of the interaction of services, to an AUTOSAR compliant Ethernet design through an integrated workflow. If other bus technologies such as CAN, LIN, or FlexRay are also to be used in addition to Ethernet, mixed topologies can also be designed. Thus PREEvision accompanies the system designer through the challenging task of combining classic embedded design with modern service orientation and the necessary back-end communication – and thereby supports the transformation of the automobile into a data center on wheels.

E/E Development for Future Vehicle Innovations
An integrated, model-based approach from architecture design to series production
The development of modern electric/electronic (E/E) architectures is a challenge today more than ever. Numerous development criteria must be taken into account, and classic vehicle domains need to be linked to new functions in the areas of driver assistance and autonomous driving. Completely new functions that are no longer limited to just the vehicle, but are also provided as services in the "IT backend" outside the vehicle, are emerging here.
The introduction of service-oriented architectures and powerful domain computers, Ethernet to on-board communication, connectivity gateways and, last but not least, increasing safety and security requirements represent profound and radical changes for every development organization. To master these complex development tasks successfully as a team, a development platform and E/E database, which can be implemented in different ways, are required.
