Abstract
A method and system for an automata-based approach to state reachability of an interacting extended finite state machine. The present invention comprises a computer system having a processor, and a memory coupled to the processor via a bus, the memory containing computer readable instructions which when executed by the processor cause the processor to implement a process in accordance with the present invention. A digital system is modeled as an extended finite state machine. Automata operations are applied to the extended finite state machine to efficiently compute a set of reachable states from an initial state. The design of the system is verified by determining whether the set of reachable states includes an undesirable state.
