This paper proposes a hardware fault localization approach

MDCI

which is based on multi-granularity dynamic control flow invariants.The approach first extracts high confidence dynamic control flow invariants in different granularity.It then checks gradually and iteratively in multi-granularity whether the dynamic control flow invariants are accessible

and localizes the code scope related to hardware faults.The experimental result shows that MDCI can localize the code scope related to hardware faults with high accuracy by checking only a few of control flow program points.
