Abstract
This paper discusses an automated method to build scan chains at the register-transfer level (RTL) for power-constrained at-speed testing. By analyzing a circuit at the RTL, where design complexity is lower than at the gate netlist level, one can divide a circuit into multiple partitions, which can be tested independently in order to reduce test power. Despite activating one partition at a time, we show how through conscious construction of scan chains, high transition fault coverage can be achieved, while reducing test time of the circuit when employing third party test generation tools. Furthermore, as shown in experimental results, by constructing scan chains for the partitioned circuit at the RTL, area and performance penalty of the design-for-test hardware may be reduced.

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
