Worst-Case Execution Time Analysis Workshop

Static WCET analysis obtains a safe estimation of the WCET of a program. The timing behaviour of a program depends in many cases on input, and an analysis could take advantage of this information to produce a formula in input variables as estimation of the WCET, rather than a constant. A method to do this was suggested in [12]. We have implemented a working prototype of the method to evaluate its feasibility in practice. We show how to reduce complexity of the method and how to simplify parts of it to make it practical for implementation. The prototype implementation indicates that the method presented in [12] successfully can be implemented for a simple imperative language, mostly by using existing libraries.
