Abstract
Resilient systems are designed to eliminate the voltage/frequency margin for further power reduction/performance improvement. With the occurrence of error detection sequential (EDS) circuits and error-path circuits, resilient systems bring in new challenges for the path delay testing. In this paper, three scan EDS designs are analyzed and compared. Then a novel OR-tree delay testing method is proposed and experimental comparison is made showing our method´s higher efficiency than a baseline method.
