Our paper “Emphasizing Functional Relevance Over State Restoration in Post-silicon Signal Tracing” establishes insufficiency of the state-of-the-art metric called State Restoration Ratio (SRR) to evaluate trace signal quality. It also presents a new post-silicon trace signal selection algorithm based on  PageRank. This paper demonstrates that optimizing SRR typically generates signals that are functionally irrelevant to the design and unusable for debugging for a comprehensive set of SRR based techniques. This paper assessed the scalability of different signal selection algorithms by applying them to an industrial scale OpenSPARC T2 design. Our results show that our new algorithm consistently outperformed other techniques with respect to scalability and functional relevance of signals selected.
