Abstract : Knowing the program timing characteristics is fundamental to the successful design and execution of real-time systems. The Worst-Case Execution Time (WCET) of a program is the longest execution time that will ever be observed when the program is run on its target hardware. The WCET is needed for many different types of system analysis for real-time systems. Timing becomes the most important factor while considering the distributed automotive embedded real-time systems. Handling real-time constraints to add more functionality to a vehicle is required while modelling these systems. In this present study the WCET estimate is obtained by measurement-based method using in-circuit emulator for a given set of input data. Many existing methods of WCET analysis require the availability of the source code of the program in order to estimate WCET. Here, the measurement-based analysis is performed which is solely based on execution traces of the program and is independent of the program semantics.
