Abstract
One of the key challenges for the FPGA industry going forward is to make the task of designing hardware easier. A significant portion of that design task is the creation of the interconnect pathways between functional structures. We present a synthesis tool that automates this process and focuses on the interconnect needs in the fine-grained (sub-IP-block) design space. Here there are several issues that prior research and tools do not address well: the need to have fixed, deterministic latency between communicating units (to enable high-performance local communication without the area overheads of latency insensitivity), and the ability to avoid generating unnecessary arbitration hardware when the application design can avoid it. Using a design example, our tool generates interconnect that requires 69% fewer lines of specification code than a handwritten Verilog implementation, which is a 32% overall reduction for the entire application. The resulting system, while requiring 6% more total functional and interconnect area, achieves the same performance. We also show a quantitative and qualitative advantages against an existing commercial interconnect synthesis tool, over which we achieve a 25% performance advantage and 15%/57% logic/memory area savings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
