Abstract
The test time for core-external interconnect shorts and opens is typically much less than that for core-internal logic. Therefore, prior work on test-infrastructure design for core-based system-on-a-chip (SOC) has mainly focused on minimizing the test time for core-internal logic. However, as feature sizes shrink for newer process technologies, the test time for signal integrity (SI) faults on interconnects cannot be neglected. The test time for SI faults can be comparable to, or even larger than, the test time for the embedded cores. We investigate the impact of interconnect SI tests on SOC test-architecture design and optimization. A compaction method for SI faults and algorithms for test-architecture optimization are also presented. Experimental results for the ITC'02 benchmarks show that the proposed approach can significantly reduce the overall testing time for core-internal logic and core-external interconnects.

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
