Abstract
We propose two new FPGA routing switch designs that are programmable to operate in three different modes: high-speed, low-power or sleep. High-speed mode provides similar power and performance to a traditional routing switch. In low-power mode, speed is curtailed in order to reduce power consumption. Our first switch design reduces leakage power consumption by 36-40% in low-power vs. high-speed mode (on average); dynamic power is reduced by up to 28%. Leakage power in sleep mode is 61% lower than in high-speed mode. A second switch design offers a 36% smaller area overhead and reduces leakage by 28-30% in low-power vs. high-speed mode. The proposed switch designs require only minor changes to a traditional routing switch, making them easy to incorporate into current FPGA interconnect. The applicability of the new switches is motivated through an analysis of timing slack in industrial FPGA designs. Specifically, we show that a considerable fraction of routing switches may be slowed down (operate in low-power mode), without impacting overall design performance.

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
