21st International Workshop on
Worst-Case Execution Time Analysis
Home | Program | Call for papers | Submission instructions | Organizers
The 21st International Workshop on Worst-Case Execution Time Analysis (WCET 2023) targets the resource-consumption analysis of embedded systems in a broad sense, with an emphasis on techniques to analyze the worst-case execution time (WCET) of real-time software. The workshop covers a wide range of topics related to embedded real-time systems, timing analysis, program analysis, as well as hardware and operating-system designs. With the goal of comprehensively meeting resource requirements, the WCET Workshop 2023 welcomes contributions of analysis techniques for resources other than time, such as energy or memory. As in previous years, the 21st edition of the WCET workshop will be co-located with the Euromicro Conference on Real-Time Systems (ECRTS 2023) in Vienna, Austria, from July 11-14, 2023.
Goals and topics
A large class of embedded systems is distinguished from general-purpose computing systems by the need to satisfy (strict) resource requirements. The analysis of such systems is often challenging due to the interaction of the physical environment with the system’s software, which, in turn, interacts with the underlying hardware. All these interactions make it difficult in practice to guarantee that a system meets all its resource requirements. Designers and engineers thus strive for their systems to be predictable and analyzable, thereby facilitating the verification of the systems’ worst-case behavior.
In order to foster vivid discussions, the workshop especially appreciates statements and approaches that are innovative or controversial. Topics of interest include, but are not limited to:
- Static/measurement-based/hybrid analysis techniques
- Program-flow analyses (e.g., loop bounds, infeasible paths)
- Microarchitectural resource-consumption modeling
- Hardware designs for predictability
- Predictable, resource-aware operating systems
- Analysis of resources other than time (e.g., worst-case energy consumption)
- Trade-offs between resource demands
- Tools for worst-case analysis
- Compiler-directed worst-case optimization & analysis
- Programming-language support for embedded systems
- Methods & benchmarks for worst-case-analysis evaluation
- Machine-learning approaches for worst-case analysis
- WCET analysis in the academic curriculum
- Integration of WCET & schedulability analysis
- Analysis of parallel applications & many-core systems
- Case studies & industrial experiences
