Reviving erroneous stability-based clock-gating using partial Max-SAT
Bibliographic record
Abstract
The conflicting yet increasing demand for high performance and low power in multi-functional chips has pushed techniques for power reduction to the forefront of VLSI design. Although recent developments have automated most of the low power implementations, designers often manually modify the circuit in order to achieve further power savings. This human intervention is often paved with many errors that are bound to typical logic functional failures. Debugging these errors can be a resource intensive process that requires considerable manual effort. This discourages engineers and achieving power savings at the micro level of the design sometimes remains unrealized. This paper proposes a novel debugging methodology to rectify erroneous clock-gating implementations. With the use of Partial Max-SAT, the method localizes and rectifies the design error introduced in the circuit during a clock-gating implementation. The net effect of the proposed methodology leads to shorter debug time ensuring additional power savings. Extensive experiments on benchmark circuits confirm the effectiveness of the approach.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
