Abstract

This paper focuses on safety model of embedded system architecture using AADL (Architecture Analysis and Design Language). It achieves both the foundation of fault model annex to specify safety requirements and the transformation from AADL safety model to DSPN (Deterministic Stochastic Petri Net) model. Then AADL architecture safety computation model can be accessed by the means of numerical simulation. To support safety assessment automatically, this paper designs and implements an AADL Safety Assessment Tool, shorted by ASAT. It is integrated into the OSATE (the Open Source AADL Tool Environment) and uses Time NET to achieve the safety assessment of DSPN model. Meanwhile, this paper presents a case study of OVP (Over Voltage Protection) system on the safety analysis and assessment to show the scenario of ASAT performance.
