Establishing that safety-critical systems are actually safe requires a large effort and involves a range of tasks, from conducting preliminary hazard analyses to creating detailed assurance cases. This paper introduces the Architecture-Supported Audit Processor, or ASAP, which generates a number of safety-specific system views that deeply integrate a system's architecture and arguments about its safety. These views are generated interactively and automatically using safety-specific extensions to the Architecture Analysis and Design Language (AADL). Though the use of the tooling and views do not require the use of any particular process, they align well with a system-theoretic approach. This paper discusses the background and use of ASAP as a demonstrative example.
