SEI Podcasts

Jun 12, 2014

In this podcast, Julien Delange discusses two extensions to the Architecture Analysis and Design Language: the behavior annex and the error-model annex. The behavior annex represents the functional logic of AADL components and interacts with the other system elements. SEI researchers are currently participating in the ongoing improvements of this extension of the AADL by connecting it to other analysis tools. The error model annex augments the architecture description by specifying safety concerns of the system (error propagation, error behavior, etc.). The language is the foundation of new analysis tools that provide qualitative and quantitative assessment of system safety and reliability. SEI researches have defined new tools that analyze the model and produces safety validation documents, such as the one required by safety standard such as the SAE ARP4761.  Listen on Apple Podcasts.
