. Given a discrete-state continuous-time reactive system, like a digital circuit, the classical approach is to ﬁrst model it as a state transition system and then prove its properties. Our contribution advocates a diﬀerent approach: to directly operate on the input-output behavior of such systems, without identifying states and their transitions in the ﬁrst place. We discuss the beneﬁts of this approach at hand of some examples, which demonstrate that it nicely integrates with concepts of self…

This monograph presents the timed input/output automaton (TIOA) modeling framework, a basic mathematical framework to support description and analysis of timed (computing) systems and a notion of receptiveness, which implies that a TIOA does not block the passage of time.

It is shown that interesting classes of hybrid systems can be abstracted to purely discrete systems while preserving all properties that are definable in temporal logic.

A unified, comprehensive presentation of simulation techniques for verification of concurrent systems is given, in terms of a simple untimed automaton model, where history and prophecy relations are defined and it is shown how invariants can be incorporated into all the simulations.

The theory provides algorithms for checking the compatibility between two interfaces and for deriving the composite interface; the theory can thus be viewed as a type system for real-time interaction.

A new approach for the design of a synthetic biological circuit whose behaviour is specified in terms of signal temporal logic STL formulae is presented, which leverages recent results on the quantitative semantics of Signal Temporal Logic.
