Abstract
A Field-Programmable Gate Array (FPGA) is an integrated circuit that allows users to program product features and functions after manufacturing. Verilog-to-Routing (VTR) is an open source CAD tool for conducting FPGA architecture and CAD research and development. As one of the core tools of VTR, Odin II is responsible for Verilog elaboration and hard block synthesis. This project describes the improvements in Odin II on three aspects: for loop support, abstract syntax tree (AST) simplification and hard block reduction. This work allows elaboration of a for loop statement by modifying the Abstract Syntax Tree (AST). There are different alternatives to simplify an AST, and this paper demonstrates three ways: simplifying expressions with variables, reducing parameters with values and using shift operations to replace multiplications or divisions. For a circuit design, some hard blocks in the netlist have the same high-level function. This project further provides a method to reduce redundant hard blocks. Each implementation is tested with designed testing cases or sets of benchmarks, and the results of running them through Odin II and VTR are demonstrated.

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.
