Abstract

In this work, we firstly enhance OZTA, a combination of Object-Z and Timed Automata, by introducing a set of timed patterns as language constructs that can specify the dynamic and timing features of complex real-time systems in a systematic way. Then we present the formal semantics in Unifying Theories of Programming for the enhanced OZTA. Furthermore, we develop an OZTA tool which can support editing, type-checking of OZTA models as well as projecting OZTA models into TA models so that we can utilize TA model checkers, e.g., Uppaal for verification.
