The paper describes safety analysis tools that have been developed for a state based requirements specification language called Requirements State Machine Language (RSML). These tools include a simulator that allows for forward and backward execution of RSML specifications, a fault tree generator that is based on backward simulation, tools to check for consistency and completeness of specifications, and additional safety analysis techniques. An example requirements specification for an Automated Highway System (AHS) is used for describing the functionality of the tools
