We propose a new algorithm for test point selection forscan-based BIST.The new algorithm combines the advantagesof both explicit-testability-calculation and gradienttechniques.The test point selection is guided by acost function which is partially based on explicit testabilityrecalculation and partially on gradients.With anevent-driven mechanism, it can quickly identify a set ofnodes whose testability need to be recalculated due toa test point, and then use gradients to estimate the impactof… CONTINUE READING
