English abstract:
The analysis of the worst-case execution time
(WCET) requires detailed knowledge of the program behavior.
In practice it is still not possible to obtain all
needed information automatically.
In this paper we present the current state of the
art of WCET analysis and point to the main problems
to be solved. The most eminent problem is the
state problem, i.e., the precise determination of possible
processor states at different program locations. The
path problem refers to the fact that current tools are
not able to calculate all (in)feasible paths automatically.
We discuss how the main open problems manifest themselves
in static and in measurement-based WCET analysis
methods.
