Today, a critical issue for complex systems design is the modeling and analysis of its architectures. Different ADLs support analyzers of different properties. For example, Unicon and MetaH allow the analysis of specific qualitative properties such as safety and security levels, while Rapide is focused on the dynamic aspect of architectures. However, the Wright ADL defines eleven standard properties related to the consistency and completeness of software architectures. These standard properties are automated and analyzed by the Wr2fdr tool accompanying the Wright ADL. In addition, the Wr2fdr tool can translate a Wright specification into another CSP acceptable by the FDR2 model-checker. Following the importance of this Wr2fdr tool, a maintenance activity of this tool was proposed in this paper. Our maintenance activity was mainly related to the implementation of these Wright standard properties. To achieve this …
