Predictable Embedded and Real-Time Systems Engineering with the Architecture Analysis & Design Language (AADL)

A Society of Automotive Engineers (SAE) standard established in 2004, the AADL provides a new framework that allows analysis of system (and system of systems) designs prior to development and supports a model-based, model-driven development approach throughout the system life cycle.

System developers in industry and researchers in leading universities in Europe and the US use AADL to predict and validate nonfunctional properties.

In addition to providing technical leaderhip for AADL development, we provide training and technical assistance to support the use of this standard language for architecture design and analysis.

SEI Reports about AADL

Return to

AADL lowers costs
in development and maintenance through

  • well-defined architecture documentation based on a precise syntax and semantics
  • a single architectural model of multi-contractor systems that supports multiple analyses
  • evaluation of the effect of architectural choices
  • early and life-cycle tracking of modeling and analysis
  • analysis of system structure and runtime behavior rather than functional behavior
  • complement to reference architectures and component-based or product-line development
