Abstract
This paper presents a novel high-resolution, high-precision time-to-digital converter (TDC) architecture targeting an FPGA implementation. The proposed architecture relies on multiple parallel tapped-delay lines, taking advantage of the fast dedicated carry-chains available within modern FPGAs. Moreover, the architecture presented in this work enables to overcome resolution limitation imposed by minimal delays, providing significant resolution enchancement over the widespread single tapped-delay line architecture. A TDC with 10 ps resolution and 24 ps precision has been implemented on a 130 nm fabrication process Virtex-II Pro FPGA. The results obtained using 10 parallel tapped-delay lines, each featuring ~27 ps resolutions, show that over 5× resolution enchancement factors can be obtained over a single tapped delay line architecture.

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
