STPA Verifier

STPA Verifier is an Eclipse plug-in to verify the STPA safety requirements with model checker tools such as SPIN and NuSMV. The STPA-generated safety requirements are automatically transformed into formal specification in LTL (linear Temporal Logic). The STPA Verifier plug-in fetches all LTL formulae from XSTPA and allows user to load the verification model of system (Promela or SMV Model). Furthermore, STPA verifier provides a configuration view of each model checker (SPIN and NuSMV) to enable user to configure the model checker with necessary parameters. It also allows users to extract the Promela model from C-Code of the software by using the ModeX tool. The tool shows the results of each LTL formula in the table with different values (syntax error, success, failed (counterexample)and incomplete).
