Measurement-based timing analysis (MBTA) is a hybrid approach that combines execution-time measurements with static program analysis techniques to obtain an estimate of the worst-case execution time (WCET) of a program. The most challenging part of MBTA is test data generation. Choosing an adequate set of test vectors determines safety and efficiency of the(More)
Measurement-based timing analysis (MBTA) is a hybrid approach that combines execution time measurements with static program analysis techniques to obtain an estimate of the worst-case execution time (WCET) of a program. In order to minimize the chance that the WCET estimate is below the real WCET, the set of representative execution-time measurements has to(More)
The goal of measurement-based WCET estimation (MBWE) is to derive an estimate of the worst-case execution time (WCET) of a given piece of software on a particular target platform by executing the software on the target hardware and analyzing the obtained time-stamped execution traces. In this paper we introduce context-sensitive MBWE, an approach that can(More)
During the design of embedded real-time systems, engineers have to consider the temporal behavior of software running on a particular hardware platform. Measurement-based timing analysis is a technique that combines elements from static code analysis with execution time measurements on real physical hardware. Because performing exhaustive measurement is(More)
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(More)
The Implicit Path Enumeration Technique (IPET) has become widely accepted as a powerful technique to compute upper bounds on the Worst-Case Execution Time (WCET) of time-critical software components. While the technique works fine whenever fixed execution times can be assumed for the atomic program parts, standard IPET does not consider the(More)
Worst case execution time analysis based on measurements requires large test suites to obtain reliable numbers. We are thus developing tools to efficiently generate these test sets in a whitebox-testing approach. To make project progress measurable and guard against regressions, a benchmarking suite is sought for. We present a set of requirements that have(More)
