Architecture Analysis & Design Language
open-in-new
<p>The Architecture Analysis & Design Language (AADL) is an <a href="/facts/Architecture_description_language/JpElRTg7">architecture description language</a> standardized by <a href="/facts/Society_of_Automotive_Engineers/cBS1MznQ">SAE</a>. AADL was first developed in the field of <a href="/facts/Avionics/F4gQJBJn">avionics</a>, and was known formerly as the Avionics Architecture Description Language. It was funded in part by the Army. </p><p>The Architecture Analysis & Design Language is derived from MetaH, an architecture description language made by the Advanced Technology Center of <a href="/facts/Honeywell/qjkujlwJ">Honeywell</a>. AADL is used to model the <a href="/facts/Software_architecture/1Hokp0Ed">software</a> and <a href="/facts/System_architecture/fDbXSn3s">hardware</a> architecture of an <a href="/facts/Embedded_system/a4muX1wU">embedded</a>, <a href="/facts/Real-time_computing/p9HxgL4L">real-time</a> system. Due to its emphasis on the embedded domain, AADL contains constructs for modeling both software and hardware components (with the hardware components named "execution platform" components within the standard). This architecture model can then be used either as a design documentation, for analyses (such as schedulability and flow control) or for code generation (of the software portion), like <a href="/facts/Unified_Modeling_Language/3tlNS0tH">UML</a>. </p>
