近年来，电子控制系统的数量显著增加。为了保持竞争力，越来越多的功能被集成到越来越强大和复杂的计算机硬件中。由于控制系统工程的这些进步，出现了分析实时计算机系统的时序行为的新挑战。确定的两个主要挑战是硬件的执行时间建模和路径问题，由于计算复杂性的限制，该路径问题禁止通过端到端测量来捕获最坏情况执行时间（WCET）。这项工作提出了我们的新的基于测量的WCET分析方法，成功地解决了这些问题的基石。我们清楚地确定我们的研究目标和我们的研究的相关性。特别是，我们的方法的新颖的方面进行了强调。结论是由一个工业规模的案例研究应用程序的简要介绍。
In the last years the number of electronic control systems has increased significantly. In order to stay competitive more and more functionality is integrated into more and more powerful and complex computer hardware. Due to these advances in control systems engineering new challenges for analyzing the timing behavior of real-time computer systems arise. The two identified main challenges are execution-time modeling of the hardware and the path problem that forbids capturing the worst-case execution time (WCET) by end-to-end measurements due to limits in computational complexity. This work presents the cornerstones of our new measurement-based WCET analysis method that successfully addresses these problems. We clearly identify our research goals and the relevance of our research. Especially, the novel aspects of our approach are emphasized. The conclusion is formed by a brief presentation of an industrial-size case study application.
