A current trend in the software engineering community is to integrate different tools in a friendly and powerful development environment for use by final users. This is also the case for tools based on formal methods, which are very valuable for increasing confidence in the reliability of software. This paper contributes to one promising approach to make this integration possible, the project FMICS-JETI. This project aims to obtain an active repository of tools based on formal methods in such a way that users can access and combine all the tools simply by defining a graph with the tools and the files they manage. In particular, the paper explains how two new modules of the well known toolset CADP are added to FMICS-JETI. These new modules, named C.OPEN and ANNOTATOR extend CADP with functions to manage C programs in this toolset.
