When custom modeling tools are used for designing complex safety-critical systems (e.g., critical cyber-physical systems), the tools themselves need to be validated by systematic testing to prevent tool-specific bugs reaching the system. Testing of such modeling tools relies upon an automatically generated set of models as a test suite. While many...

The verification of the time-dependent behavior of safety-critical systems is important, as design problems often arise from complex timing conditions. One of the most common formalisms for modeling timed systems is the timed automaton, which introduces clock variables to represent the elapse of time. Various tools and algorithms have been develope...

Formal analysis of real time systems is important as they are widely used in safety critical domains. Such systems combine discrete behaviours represented by control states and timed behaviours represented by clock variables. The counterexample-guided abstraction refinement (CEGAR) algorithm utilizes the fundamental technique of abstraction to syst...
