Abstract

fetched live from OpenAlex

Scan chain division has been successfully used to control shift power by enabling mutually exclusive flip-flops at different times during the scan cycle. However, to control capture power without losing transition fault coverage during at-speed scan test, the existing automatic test pattern generation (ATPG) flows need to be modified. In this paper, we present a novel scan chain division algorithm that analyzes the signal dependencies and creates the circuit partitions such that both shift and capture power can be reduced when using the existing ATPG flows. This novel algorithm has been designed for the broadside test application strategy, and a technique for employing partial scan when dividing the scan chains is also proposed.

Not 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.
