<p>Real time systems, used in most of the day-to-day applications, require time critical exection of tasks. Worst Case Execution Time Analysis (WCET) is performed to ensure the upper bound on the time they can take to execute. This work aims to perform a static analysis of the industry standard code segments to provide valuable information to aid in choosing the right apporach towards WCET analysis. Any code segment can be analyzed syntactically, to gain some insights to the effects that a particular coding syntax format may have. With focus on the functions and looping statements, vaulable information regarding the code segments inspected can be obtained. For this purpose, the code segments from CC systems, Vasteras , were inspected. Scope graphs generated by SWEET, the Swedish Execution Time tool were used extensively to aid this work. It was found that syntactical analysis could be performed effectively for the code segments that were analysed as a part of this task.</p>
