Abstract
A new software-based hybrid test vector compression method for testing system-on-a-chip (SOC) using an embedded processor is presented in this paper. In the proposed approach, a software program is first loaded into the on-chip processor memory core together with the compressed test data set. In order to reduce on-chip storage as well as testing time, the large volume of test data input is compressed in a hybrid fashion before being downloaded into the processor. The method combines a set of adaptive coding techniques for the required test data compression. The compression program, however, need not be loaded into the embedded processor, since only the decompression of test data is necessary for application by the automatic test equipment (ATE). Most importantly, this software-based hybrid scheme requires minimal hardware overhead, while the on-chip embedded processor core can be reused for normal operation after the testing is completed. In the paper, only the compression part of the technique is presented, and the efficiency of the suggested hybrid approach is demonstrated through simulation experiments on ISCAS 85 combinational and ISCAS 89 full-scan sequential benchmark circuits

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
