Abstract

A reconfigurable MBIST method based on an adaptive March algorithm is provided. The reconfigurable MBIST method automatically reconfigures different algorithm circuits according to external environment and user instructions to satisfy detection requirements for different faults. The provided adaptive March algorithm is capable of adaptively reorganizing algorithms with different complexities, such that dynamic adjustments can be executed between time complexities of the algorithm and fault coverage rates to achieve a good balance, and the static fault coverage rates are high, thereby effectively improving dynamic fault coverage rates.
