The safety of our day-to-day life depends crucially on the correct
functioning of embedded software systems which control the
functioning of more and more technical devices. Many of these
software systems are time-critical. Hence, computations performed
need not only to be correct, but must also be issued in a timely
fashion. Worst case execution time (WCET) analysis is
concerned with computing tight upper bounds for the execution time
of a system in order to provide formal guarantees for the proper
timing behaviour of a system. Central for this is to compute safe
and tight bounds for loops and recursion depths. In this paper, we
highlight the TuBound approach to this challenge at whose heart is a
constraint logic based approach for loop analysis.
