When designing today's highly complicated systems consisting of several hardware and software modules, it is essential to estimate the performance such as worst-case or best-case execution time in early design stages. Such estimation is essential to explore architecture and hardware/software partitioning in system-level design. A maximum execution time estimated topologically without considering false-paths is longer than the real. In this paper, we propose an static estimation method of maximum execution time in system-level designs, considering false-paths. Also, we adopt an approximation approach in order to avoid the path explosion problem. The experimental results show that our method can provide much smaller estimated maximum execution time than the method without considering false-paths. At the same time, the results show us that the maximum execution time can be estimated to a very small range, by applying both simulation-based method and our static method.
