Abstract
This paper describes the authors’ experience with static analysis of both WCET and stack usage of a satellite on-board software subsystem. The work is a continuation of a previous case study that used a dynamic WCET analysis tool on an earlier version of the same software system. In particular, the AbsInt aiT tool has been evaluated by analysing both C and Ada code generated by Simulink within the UPMSat-2 project. Some aspects of the aiT tool, specifically those dealing with SPARC register windows, are compared to another static analysis tool, Bound-T. The results of the analysis are discussed, and some conclusions on the use of static WCET analysis tools on
the SPARC architecture are commented in the paper.
