Abstract
The importance of on-chip power-rail inductance in generating delta-I power-supply noise is examined in this paper using systematic circuit simulation of the complete integrated-circuit power net. This source of noise is compared to the resistive IR drop in the net, and to the delta-I noise due to both high-inductance- and low-inductance-bonding packages. Results are presented for a typical on-chip power net in 0.18 μm CMOS technology, and it is demonstrated that the inductance of this on-chip power net is the dominant contributor to the full-chip power-supply noise. The simultaneous switching events which produce the triggering current transients for the delta-I noise are taken to arise from core-logic switching; the mitigating, de-coupling role of the capacitance of non-switching gates within the core-logic block is considered.

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
