Methodologies for Specification of Real-Time Systems Using Timed I/O Automata

We present a real-time specification framework based on Timed I/O Automata and a comprehensive tool support for it. The framework supports various design methodologies including: top-down refinement--for decomposition of abstract specifications towards increasingly detailed models; bottom-up abstraction--for synthesis of complex systems from more concrete models; and step-wise modularisation of requirements--to factor out behaviours given by existing available components from a complex global requirements specification to be implemented. These methodologies are realized by consecutive applications of operators from the following set: refinement, consistency checking, logical and structural composition and quotienting. Additionally, our tool allows combining the component-oriented design process with verification of temporal logic properties increasing the flexibility of the process.
