Research and Technology Highlight Industry Standard Notation for Architecture-Centric

cepts from research in software architecture into an international standard suite for modeling and analyz-ing the architecture of the operational software, the computer system, and the mission system of safety-critical, performance-critical, and mission-critical software-reliant systems in order to facilitate next gen-eration industrial model-based embedded systems engineering practice. AADL’s well-defined semantics that include specification of architecture dynamics in terms of modes and standardized mechanism for semantically consistent extensions provides the basis for automatically deriving analytical models to vali-date non-functional requirements (such as performance, safety, security and reliability) through formal analysis and simulation. In addition it supports auto-generation of application-specific runtime executives and rapid system construction from validated AADL models. The standardized AADL XMI interchange format facilitates model interchange between organizations, interfaces with existing and emerging analy-sis tools, and supports system validation through analysis of integrated subsystem AADL models.
