Relational Concurrent Refinement: Timed Refinement
Data refinement in a state-based language such as Z is defined using a relational model in terms of the behaviour of abstract programs. Downward and upward simulation conditions form a sound and jointly complete methodology to verify relational data refinements, which can be checked on an event-byevent basis rather than per trace. In models of concurrency, refinement is often defined in terms o...
متن کاملRelational Concurrent Refinement: Automata
Data refinement in a state-based language such as Z is defined using a relational model in terms of the behaviour of abstract programs. Downward and upward simulation conditions form a sound and jointly complete methodology to verify relational data refinements. In models of concurrency, refinement takes a number of different forms depending on the exact notion of observation chosen, which can ...
متن کاملMore Relational Concurrent Refinement: Traces and Partial Relations
Data refinement in a state-based language such as Z is defined using a relational model in terms of the behaviour of abstract programs. Downward and upward simulation conditions form a sound and jointly complete methodology to verify relational data refinements. On the other hand, refinement in a process algebra takes a number of different forms depending on the exact notion of observation chos...
متن کاملGuarded Operations, Refinement and Simulation
Simulation rules have long been used as an effective computational means to decide refinement relations in state-based formalisms. Here we investigate how they might be amended so as to decide the event-based notion of singleton failures refinement of abstract data types, or processes, that have operations with a “guarded” interpretation.
متن کاملInformation flow in systems with schedulers, Part II: Refinement
Refinement is a relation on systems models: a concrete model is a refinement of a more abstract model if it has fewer behaviours. When properties of the abstract model are guaranteed to be preserved in the concrete model, refinement supports a top-down development process. This paper considers preservation of a range of information flow security properties in synchronous systems with schedulers...
