Abstract
This paper describes GlitchLess, a circuit-level technique for reducing power in field-programmable gate arrays (FPGAs) by eliminating unnecessary logic transitions called glitches. This is done by adding programmable delay elements to the logic blocks of the FPGA. After routing a circuit and performing static timing analysis, these delay elements are programmed to align the arrival times of the inputs of each lookup table (LUT), thereby preventing new glitches from being generated. Moreover, the delay elements also behave as filters that eliminate other glitches generated by upstream logic or off-chip circuitry. On average, the proposed implementation eliminates 87% of the glitching, which reduces overall FPGA power by 17%. The added circuitry increases the overall FPGA area by 6% and critical-path delay by less than 1%. Furthermore, since it is applied after routing, the proposed technique requires little or no modifications to the routing architecture or computer-aided design (CAD) flow.

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
