Frama-C gathers several analysis techniques in a single collaborative framework, based on analyzers (called "plug-ins") that can build upon the results computed by other analyzers in the framework. Thanks to this approach, Frama-C provides sophisticated tools, including:

• an analyzer based on abstract interpretation (Value plug-in);
• a program proof framework based on weakest precondition calculus (WP plug-in);
• a program slicer (Slicing plug-in);
• a tool for verification of temporal (LTL) properties (Aoraï plug-in);
• several tools for code base exploration and dependency analysis (plug-ins From, Impact, Metrics, Occurrence, Scope, etc.). These plug-ins communicate between each other via the Frama-C API and via ACSL (ANSI/ISO C Specification Language) properties.
