AS5506D Architecture Analysis & Design Language (AADL)

This Architecture Analysis & Design Language (AADL) standard document was prepared by the SAE AS-2C Architecture Description Language Subcommittee, Embedded Computing Systems Committee, Aerospace Avionics Systems Division.

The language was originally published as SAE AS5506 in 2004. The language has been refined and extended based on industrial experience as AADL V2 and published as AS5506A in 2009. The improvements focused on better support for architecture templates and modeling of layered and partitioned architectures. AADL V2.1, a revision that addresses a number of errata that have been reported and agreed upon by the committee, was published as AS5506B in 2012. A subsequent revision, AS5506C or AADL V2.2, has been published in 2017. This third revision addresses a number of additional errata and minor improvements to the language since AS5506C. These errata and changes have been approved by the committee.
