Towards limiting the impact of timing anomalies in complex real-time processors

Abstract

Timing verification of embedded critical real-time systems is hindered by complex designs. Timing anomalies, deeply analyzed in static timing analysis, require specific solutions to bound their impact. For the first time, we study the concept and impact of timing anomalies in measurement-based timing analysis, the most used in industry, showing that they require to be considered and handled differently. In addition, we analyze anomalies in the context of Measurement-Based Probabilistic Timing Analysis, which simplifies quantifying their impact.
