Abstract
Although integrated modular avionics (IMA) provides many advantages such as the reduced weight and higher efficiency for system operations, safety problems in IMA dynamic reconfiguration process come up due to its complexity to analyze. Architecture Analysis and Design Language (AADL) has advantage to model for embedded systems. However, it is quite limited to employ AADL for analyzing system safety. This paper, seeks to translate the AADL models of IMA dynamic reconfiguration process into colored petri net (CPN), which have advantages to simulate and evaluate embedded systems. Then, the colored petri net (CPN) is proposed for the analysis for AADL models, because CPN can describe the properties and behaviors of dynamic reconfiguration process well. Moreover, it is essential to make a transformation from the AADL models to the CPN models. This work will benefit the subsequent analysis of IMA dynamic reconfiguration process. Finally, a case study is provided for effectiveness the transformation rules.
