The WCET Tool Challenge 2011

Following the successful WCET Tool Challenges in 2006 and 2008, the third event in this series was organized in 2011, again with support from the ARTIST DESIGN Network of Excellence. Following the practice established in the previous Challenges, the WCET Tool Challenge 2011 (WCC'11) defined two kinds of problems to be solved by the Challenge participants with their tools, WCET problems, which ask for bounds on the execution time, and flow-analysis problems, which ask for bounds on the number of times certain parts of the code can be executed. The benchmarks to be used in WCC'11 were debie1, PapaBench, and an industrial-strength application from the automotive domain provided by Daimler AG. Two default execution platforms were suggested to the participants, the ARM7 as "simple target'' and the MPC5553/5554 as a "complex target,'' but participants were free to use other platforms as well. Ten tools participated in WCC'11: aiT, Astr\'ee, Bound-T, FORTAS, METAMOC, OTAWA, SWEET, TimeWeaver, TuBound and WCA

An SCR-extension for Enterprise Architect

"Software Cost Reduction" ist ein 1978 von David Parnas entwickelter Ansatz, um Spezifikationen für Steuergeräte formal prüfbar und gleichzeitig kompakt zu formulieren. Nach diversen Einsätzen im Umfeld des US-Militärs ist der Ansatz inzwischen weitgehend in Vergessenheit geraten. Diese Arbeit greift die SCR-Spezifikationssprache auf und passt sie für den Einsatz mit dem modernen UML-Werkzeug Enterprise Architect an. Neben dem Sprachprofil werden hierzu ein Compiler und Codegeneratoren für C# und ANSI-C entwickelt."Software Cost Reduction" is a method developed by David Parnas in 1978 to develop both formal and compact specifications for software systems. After several uses in the general vicinity of the US military, this approach has become mostly forgotten. This thesis picks up the SCR specification language again and adapts it for use with the modern UML modelling tool Enterprise Architect. Along with the UML language profile, a compiler and code generators for C# and ANSI C are being developed
