TimeWeaver: A Tool for Hybrid Worst-Case Execution Time Analysis

Authors: Daniel Kästner, Markus Pister, Simon Wegener, and Christian Ferdinand

Published in: OASIcs, Volume 72, 19th International Workshop on Worst-Case Execution Time Analysis (WCET 2019)

Abstract
Many embedded control applications have real-time requirements. If the application is safety-relevant, worst-case execution time bounds have to be determined in order to demonstrate deadline adherence. For high-performance multi-core architectures with degraded timing predictability, WCET bounds can be computed by hybrid WCET analysis which combines static analysis with timing measurements. This article focuses on a novel tool for hybrid WCET analysis based on non-intrusive instruction-level real-time tracing.

Teaching WCET Analysis in Academia and Industry: A Panel Discussion

Authors: Niklas Holsti, Guillem Bernat, Christian Ferdinand, Peter Puschner, and Reinhard Wilhelm

Published in: OASIcs, Volume 10, 9th International Workshop on Worst-Case Execution Time Analysis (WCET'09) (2009)

Abstract
The last item on the programme of the WCET'09 workshop was a panel discussion on "Teaching WCET analysis in academia and industry". The panelists presented three position statements to initiate a general discussion of the subject. This summary contains the panelists' position statements and notes of the panel discussion.

Towards Formally Verifiable WCET Analysis for a Functional Programming Language

Authors: Kevin Hammond, Christian Ferdinand, Reinhold Heckmann, Roy Dyckhoff, Martin Hofman, Steffen Jost, Hans-Wolfgang Loidl, Greg Michaelson, Robert Pointon, Norman Scaife, Jocelyn Sérot, and Andy Wallace

Published in: OASIcs, Volume 4, 6th International Workshop on Worst-Case Execution Time Analysis (WCET'06) (2006)

Abstract
This paper describes ongoing work aimed at the construction of formal cost models and analyses to yield verifiable guarantees of resource usage in the context of real-time embedded systems. Our work is conducted in terms of the domain-specific language Hume, a language that combines functional programming for computations with finitestate automata for specifying reactive systems. We outline an approach in which high-level information derived from source-code analysis can be combined with worst-case execution time information obtained from high quality abstract interpretation of low-level binary code.
