Logic-level mapping of high-level faults

The paper presents an accurate analysis of the correlation between high-level fault models and the gate-level stuck-at fault model and it proposes a strategy to map high-level faults into logic-level faults. Thus, functional verification, based on a high-level fault model, can be performed by exploiting the capability of state of the art logic-level ATPGs. Experimental results highlight the effectiveness of the methodology.
