Abstract
This paper proposes the use of an instrumentation layer in the die stack of a 3D-stacked IC for making precision on-chip measurements for silicon debug, device ramp-up and calibration purposes. As the instrumentation die communicates with the IC stack via the 1149.4 test bus, it can be removed from the stack to reduce the overall cost of the IC when in full production mode. Design effort on a full suite of analog instruments can be performed once and shared between different IC implementations, thereby reducing development costs. The initial focus of this work is on the development of a set of instruments that will be used to characterize the through-silicon via(s) (TSVs) of a 3D-CMOS process. Circuit details related to the design of a 3D-SIC using the Tezzaron 2-Tier 130 nm CMOS process are outlined.

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
