Static worst-case execution time (WCET) analysis is done by modeling the hardware behavior. In this paper we describe a WCET analysis technique to analyze systems with function caches, a special kind of instruction cache that caches whole functions only. This cache was designed with the aim to be more predictable for the worst-case than existing instruction caches. Within this paper we developed a cache analysis technique for the function cache. One of the new concepts of this analysis
