Abstract
The progressive shrinking of device size in advanced technologies leads to miniaturization and performance improvements. However, ultra-deep sub-micron technologies are more vulnerable to soft errors. Error analysis of a complex system with a sufficiently large sample of vulnerable nodes takes a large amount of time. In this paper we propose RASVAS, a hierarchical statistical method to model, analyze, and estimate the behavior of a system in the presence of Single Event Transients (SETs) modeled at different abstraction levels. Gate level propagation tables are developed to abstract SET propagation conditions and probabilities from gate level models. At RTL, these tables are utilized to model the underlying probabilistic behavior as Markov Decision Process (MDP) models. Experimental results demonstrate that RASVAS is orders of magnitude faster than contemporary techniques and also handle designs as large as 256-bit adders while maintaining accuracy.

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
