Advanced Techniques for WCET Analysis and Robustness in MpSoC Design and Optimization

This document presents state-of-the-art methodologies and tools for analyzing Worst-Case Execution Time (WCET) and Best-Case Execution Time (BCET) within multi-processor systems on chip (MpSoC). It covers various approaches, including configuration of performance models, sensitivity analysis through evolutionary algorithms, and the application of formal methods for ensuring whole-system reliability. Additionally, we explore scenarios highlighting dynamic migration, scheduling effects in real-time environments, and the integration of advanced runtime prediction frameworks.
