Abstract
Modern heterogeneous FPGAs contain "hard" specific-purpose structures such as blocks of memory and multipliers in addition to the completely flexible "soft" programmable logic and routing. These hard structures provide major benefits, yet raise interesting questions in FPGA CAD and architecture. To develop high-quality CAD mapping algorithms for these structures, and indeed to measure the quality of proposed new structures in the architectural domain, it is essential to have a flexible tool at the RTL synthesis level that permits heterogeneous FPGA CAD and architecture experimentation. In this paper we present a synthesis tool, called Odin, and an algorithm that permits flexible targeting of hard structures in FPGAs. Odin maps Verilog designs to two different FPGA CAD flows: Altera's Quartus, and the academic VPR CAD flow. We have expended significant effort to make the quality of this tool comparable to an industrial front-end synthesis tool, and we present mapping results for our benchmarks that show the quality of our results.

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
