Abstract
Disproportionate instantaneous power dissipation may result in unexpected power supply voltage fluctuations and permanent circuit damage. Therefore, estimation of maximum instantaneous power is crucial for the reliability assessment of VLSI chips. Circuit activity and consequently power dissipation in CMOS circuits are highly input-pattern dependent, making the problem of maximum power estimation computationally hard. This work proposes a novel pseudo-boolean satisfiability based method that reports the exact input sequence maximizing circuit activity in combinational and sequential circuits. The method is also extended to take multiple gate transitions into account by integrating delay information into the pseudo-boolean optimization problem. An extensive suite of experiments on ISCAS85 and ISCAS89 circuits confirms the efficiency and robustness of the approach compared to simulation based techniques and encourages further research for low-power solutions using boolean satisfiability.

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
