What is Capella?

Capella is an open-source Model-Based Systems Engineering (MBSE) tool and methodology developed by Thales. It's used for system, software, and hardware architecture design. Capella enables engineers to model complex systems, analyze their behavior, and generate system specifications. It emphasizes a top-down approach, starting with operational needs and gradually refining the design through various abstraction levels (operational, system, logical, and physical architectures). It is commonly used in aerospace, automotive, and defense industries.
