Abstract
Versatile Place and Route (VPR) enabled the exploration of diverse FPGA architectures. OpenFPGA extended VPR through bitstream generation and added silicon compilation. Our work is one of several efforts to use this combination to build commercial devices, which, to achieve competitiveness, has necessitated several improvements to routing and elsewhere for area, power, and performance. Fitting to the MCNC and VTR benchmarks using this work, our first improved routing pattern yields a 22% reduction in metal loading, a 14% reduction in routing multiplexer input pin count per function tile, and a 10% reduction in source to farthest sink paths. For this, routed length increased 5%, the proportion of net detours increased 11%, router heap operations increased 16%, and router iterations increased 42%, as the unmodified VPR router worked harder on routing with fewer switches but without introducing any routing failures. This work provides the first steps to a routing compiler for OpenFPGA/VPR, much as ASIC/SoC flows use a memory compiler.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
