Maximal multiple fault coverage using single fault test sets
Bibliographic record
Abstract
In this paper, an analysis based on the sensitization structure behavior in the existance of multiple faults for the general class of combinational circuits is presented. The analysis is based on partitioning the set of primary inputs into three subsets S/sub e/ (excitation set), S/sub p/ (persistency set), and S/sub c/ (control set). The problem of augmenting a single fault test set to obtain a maximal multiple fault coverage is formulated as the one of maximizing the number of primary inputs in the S/sub c/ set (or minimizing the number of primary inputs in S/sub p/) It is shown that this analysis can be used in extending single fault test sets in order to achieve a maximal multiple fault coverage. We have presented a procedure for augmenting any single fault test set. An experiment has been carried out on the 74LS181 ALU using twelve single fault test sets. It is shown that different fault classes can be covered using the procedure presented in this paper. A 100% double fault coverage for all the single fault tests is achieved.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
