Abstract
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Silicon debug is becoming a key step in the implementation flow for the purpose of identifying and fixing design errors that have escaped pre-silicon verification. To address the lack of observability for the internal circuit nodes during silicon debug, embedded logic analysis enables real-time data acquisition from a limited number of internal signals. In this paper, we propose a novel architecture for embedded logic analysis that enables real-time lossless compression of debug data. To quantify the gain from using lossless compression in embedded logic analysis, we present a new compression-ratio metric that captures the trade-off between the area and the increase in the observation window. The proposed architecture is particularly suitable for in-field debugging on application boards, which have asynchronous events that inhibit the deterministic replay of debug experiments. </para>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
