Abstract

fetched live from OpenAlex

Bisection with restarts (Yang and Greenstreet, 2007) provides a way to quantify the failure probabilities of real-world synchronizer circuits. More recently (Reiher et al., 2018) showed how time-varying, linear dynamics can be derived for non-linear synchronizer circuits building upon the bisection with restarts method. Here, we show that this linear model can be decomposed into component-wise contributions to synchronizer performance. This enables automatic optimization of device sizing to minimize the probability of failure. Furthermore, we can compare existing designs, optimizing each circuit to provide a fair comparison. The component-wise analysis explains the differences between designs by showing how each device contributes to metastability resolution over the time allotted for synchronization.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
