We give timed automaton models for a class of Programmable Logic Controller (PLC) applications, that are programmed in a simple fragment of the language Instruction Lists as defin...
Message Sequence Charts (MSCs) are an appealing visual formalism mainly used in the early stages of system design to capture the system requirements. However, if we move towards a...
This paper presents assume-guarantee style substitutivity results for the recently published timed I/O automaton modeling framework. These results are useful for decomposing verifi...
A logic model checker can be an effective tool for debugging software applications. A stumbling block can be that model checking tools expect the user to supply a formal statement...
