Abstract
This paper presents a new approach to create boundary condition independent thermal compact models based on the multidimensional model reduction (MDMR) technique. A methodology is developed for the generation of a multi dimensional compact model (MDCM) from a detailed numerical model. The MDCM is shown to have a number of advantages over resistor network models. The generation of the model is at least an order of magnitude faster then the creation of an optimized network model. The MDCM displays very high accuracy typically better than 0.1%, is very flexible allowing for the prediction of all internal temperatures, and presents no limitations on the external configuration of the compact model. A generic multi-chip module ball grid array (MCMBGA) package is used to demonstrate the technique. The MDCM created shows to have high predictive capability, boundary condition independence and a small model size. Finally, by connecting the MDCM to a printed circuit board model and simulating the system, speed ups of around 100 times are achieved.

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
