Eclipse Capella - An open-source MBSE tool for system and software architecture design based on the ARC ADIA method.

## Overview of Eclipse Capella Eclipse Capella is an open-source Model-Based Systems Engineering (MBSE) tool designed for system and software architecture development. It is based on the ARC ADIA methodology and supports the V-cycle validation process. Capella enables multidisciplinary teams to collaborate on a unified platform, ensuring design consistency and integrity. It is widely adopted in industries like automotive electronics, aerospace, energy, and transportation. ## Industries Using Eclipse Capella Eclipse Capella is extensively used in industries requiring complex system design, including: - Automotive electronics (e.g., control systems) - Aerospace (e.g., aircraft systems) - Energy (e.g., power grid modeling) - Transportation (e.g., rail systems) Notable case studies include Rolls-Royce, ArianeGroup, and CNES. ## Overview of Eclipse Capella Eclipse Capella offers the following features: - **ARC ADIA Methodology**: Model-driven systems engineering approach. - **V-Cycle Validation**: Supports verification and validation of complex systems. - **Collaboration**: Enables team-based modeling with consistency checks. - **Extensibility**: Customizable via plugins and integrations (e.g., requirements management, documentation generation). - **Cross-Industry Adaptability**: Flexible for diverse engineering workflows. ## ARC ADIA Methodology in Capella The ARC ADIA method is a model-based systems engineering framework integrated into Eclipse Capella. It covers all engineering phases, including: - Requirements analysis - System architecture design - Validation and verification It replaces traditional document-driven approaches with model-centric workflows, improving traceability and reducing errors. ## V-Cycle Validation in Capella Eclipse Capella implements the V-cycle validation process by: 1. **Design Phase**: Creating system models (left side of the V). 2. **Verification Phase**: Validating models against requirements (bottom of the V). 3. **Integration Phase**: Testing subsystems iteratively (right side of the V). This ensures correctness and reliability, especially for safety-critical systems like automotive controls or aerospace components. ## Eclipse Capella Resources Official resources include: - **Website**: [mbse-capella.org](https://mbse-capella.org/) (downloads, documentation, case studies). - **Add-Ons**: [Open-Source and Commercial Plugins](https://mbse-capella.org/addons.html). - **Training**: [Services Page](https://mbse-capella.org/services.html) for coaching and maintenance. - **Case Studies**: Detailed PDFs (e.g., [Rolls-Royce](https://mbse-capella.org/resources/pdf/Case_Study_Rolls_Royce.pdf)). ## Eclipse Capella Case Studies Documented case studies include: - **Rolls-Royce**: Aerospace system design. - **ArianeGroup**: Space launch vehicle development. - **CNES**: French space agency projects. These demonstrate Capella’s effectiveness in large-scale, safety-critical applications. Full case studies are available on the [official website](https://mbse-capella.org/case_studies.html). ## Open-Source Nature of Eclipse Capella Yes, Eclipse Capella is open-source under the Eclipse Foundation’s PolarSys initiative. It allows: - Free access to core modeling tools. - Community-driven development and extensions. Commercial add-ons and professional support are also available via third-party providers like Obeo. ## Requirements Management in Capella Capella supports requirements management through: - **Traceability**: Linking requirements to model elements. - **Validation**: Ensuring designs meet specified requirements. - **Documentation**: Auto-generating reports for audits. Integrations with tools like DOORS or Polarion can further enhance this functionality. ## Support for Eclipse Capella Users can access: - **Community Support**: Forums and documentation. - **Professional Services**: Training, coaching, and plugin development (e.g., [Obeo’s offerings](https://www.obeosoft.com/en/capella-professional-offer#integration)). - **Books**: Guides on Arcadia and Capella methodologies (e.g., [Elsevier publications](https://www.elsevier.com/books/systems-architecture-modeling-with-the-arcadia-method/roques/978-1-78548-168-0)). ### Citation sources: - [Eclipse Capella](https://mbse-capella.org) - Official URL Updated: 2025-04-01
