Abstract
The purpose of this thesis is to introduce a modified packing and placement algorithm for FPGAs that utilizes logic duplication to improve performance. The modified logic-packing algorithm was designed to leave unused basic logic elements (BLEs) in timing critical clusters, to allow potential targets for logic duplication. The modified placement algorithm consists of a new stage in which logic duplication is performed to shorten the length of the critical path. In this paper, we show that in a representative FPGA architecture using .18 μm technology, the length of the final critical path can be reduced by an average of 14.2%. Approximately half of this gain comes directly from the changes to the logic-packing algorithm while the other half is a result of logic duplication performed.

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
