From Verification to Implementation: UPPAAL to C++

Validation and Verification of safety critical systems is crucial and if done incorrectly can result in fatal loss. The research contribution is focused on providing the transformation mechanism from software verification to source code phase of software development life cycle. Modeling of the critical systems initializes with the formalism of requirements followed by early model verification. The verified model can be automated to get the high level language code via code generator. Basic steps of transformation starts with UPPAAL timed automaton as an input, then getting the XML structure of the automaton. On the basis of XML structure parse tree is generated to visualize the data structure to be used for the C++ source code generation. Finally the verification, kernel and elapsed time used by the safety, liveness, reachability, deadlock freeness properties and fairness property is presented. In real time systems, safety and deadlock freeness properties are among the most crucial verification properties because if the system is not safe then it leads to insecurities related to life, money, reputation and time. If the system is in deadlock state then the system is simply of no use. Thus verification of safety and deadlock freeness properties is mandatory as per the statistical report provided in the research.
