摘要：

Reconfigurable Scan Networks (RSNs) access embedded instruments throughout the whole system lifecycle. To support dependability management by means of RSNs, RSNs themselves must be continuously tested. The paper-at-hand presents the first online periodic test method for RSNs. The developed algorithm generates a short sequence of test patterns, which tests all parts of an RSN. The generated sequence is uploaded on-chip and is applied periodically to avoid fault accumulation in RSNs. The overall test application time is minimized to comply with the timing requirements of the well-known safety standards. The experimental results show that the method is efficient for all considered RSN designs and is scalable with the increasing size and complexity of RSNs.
