Thermal stress monitoring using gradient direction sensors
Bibliographic record
Abstract
During the development of a VLSI (Very Large Scale Integration) circuits; their internal stress due to packaging combined with local self heating becomes serious and may result in large performance variation, circuit malfunction and even chip cracking. Surface peaks thermal detection is necessary in large VLSI circuits. This paper presents a VLSI circuit thermal stress monitoring approach using surface peak thermal detector algorithm and GDS (Gradient Direction Sensors) method. The design of surface peak thermal detector algorithm (SPTDA) with flexible modular-based architecture will be presented. Several approaches were implemented to achieve a better performance for the SPTDA algorithm operation. A parallel processing strategy is used to minimize computational delay. Furthermore, a hardware-efficient factoring approach for calculating tangent and division functions required by SPTDA algorithm is used to minimize silicon space in regards of their implementation. Description of the algorithm developed for the surface peaks thermal detection and the architecture implementation results are reported and compared with finite element method (FEM) temperature computations.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
