Architecture Journey and Continuous Architecture
E/E architecture is the first of five enablers that help you develop Software-Defined Vehicles (SDVs) quickly and efficiently. Architecture and system design go hand in hand with continuous, agile software development and integration. You achieve this synergy through an aligned design process for software developers and system architects.
PREEvision provides the backbone to make this alignment a reality. When developing SDV solutions, the focus often lands solely on software development and integration. This involves well-known best practices: agile development, rapid iterative updates, common repositories for code changes, automated testing, DevOps, and software factories.
SDV Beyond Software
The goal is clear: establish building pipelines that enable continuous delivery. This allows you to respond instantly to market demands and user feedback. While this is a prerequisite for successful SDV development, it only tells half the story.
A true SDV solution takes a holistic view. It solves the challenge of designing a consistent system architecture that integrates components developed by diverse teams. You synchronize the architecture and development journeys so they work synergistically, remaining completely true to agile and CI/CD principles.
Today, aligning design processes for software developers and system architects often reveals friction. You smooth out these processes and address the challenges by using an architectural design backbone that actively nurtures the developer journey.
Overcome the Toxic Trio
In modern development scenarios, you frequently encounter fragmented toolchains spanning requirements engineering, architecture design, and series development. This creates numerous transitions and interfaces. In agile environments, you face these transitions constantly – often with every single sprint.
This fragmentation demands excessive effort for quality assurance and increases the risk of errors. It creates data silos moving in different directions, at different speeds, with varying quality. This "toxic trio" of fragmentation, transitions, and silos directly contradicts the needs of SDV development.
You avoid this friction with PREEvision. By providing an all-connecting backbone, PREEvision eliminates silos and reduces interfaces, driving your development forward.
Design and Evaluate Your Architecture
To develop a robust, cost-optimized SDV system, PREEvision enables you to design and evaluate architecture alternatives from the earliest development phases. You define and weigh the success factors of your architecture directly.
- Multi-Dimensional Evaluation: Compare architectures across different vehicle variants. You evaluate crucial targets such as weight, costs, installation space, bus load, timing, and security requirements simultaneously.
- Domain-Specific Graphical Language: Develop all aspects of your architecture using a feature-rich, layered data model. You navigate seamlessly from logical and software architecture to topology, communication design, and hardware geometry using dedicated diagrams and tables.
- Metric Framework: Calculate specific parameters to benchmark alternative designs. You utilize a powerful, Java-based metric framework to run quantitative evaluations against your current model data instantly.
- Continuous Consistency: Ensure your architecture variants are both promising and valid. You run automated consistency checks continuously in the background or manually against fully customizable rules.
