It is probably very hard to develop a new model checker that is faster than UPPAAL for verifying (correct) timed automata. In fact, our tool MCTA does not even try to compete with UPPAAL in this (i. e., UPPAAL’s) arena. Instead, MCTA is geared towards analyzing incorrect specifications of timed automata. It returns (shorter) error traces faster.

UPPAAL is a tool suite for automatic verification of safety and bounded liveness properties of real-time systems modeled as networks of timed automata [12, 9, 4], developed during the past two years. In this paper, we summarize the main features of UPPAAL in particular its various extensions developed in 1995 as well as applications to various case-studies, review and provide pointers to the th...

David, A. 2003: Hierarchical Modeling and Analysis of Timed Systems. IT Technical report series 2003-050 178 pp. Uppsala. ISSN 1404-3203. Uppaal is a tool for model-checking real-time systems developed jointly by Uppsala University and Aalborg University. It has been applied successfully in case studies ranging from communication protocols to multimedia applications. The tool is designed to ver...

In this paper we apply the tool Uppaal to an automatic analysis of a version of the Philips Audio Control Protocol with two senders and bus collision handling. This case study is signi cantly larger than the real-time/hybrid systems previously analysed by automatic tools. During the case study the tool Uppaal was extended with a new feature, committed locations, allowing e cient modelling of br...

In this paper, we evaluate the effectiveness of model slicing to provide assurance about correctness of SystemC TLM programs. The need for such assurance is important since SystemC has become a de-facto standard for building systems with hardware/software co-design. Existing approaches that enable one to transform the given SystemC TLM program into an UPPAAL model that can be verified suffer fr...

Modeling and analysis of nonfunctional requirements is crucial in automotive systems. EAST-ADL is an architectural language dedicated to safety-critical automotive system design. We have previously modified EAST-ADL to include energy constraints and transformed energy-aware timed (ET) behaviors modeled in SIMULINK/ STATEFLOW into UPPAAL models amenable to formal verification. Previous work is e...
