It has been shown that the delay of a target path can be composed linearly of other path delays. If the later paths are robustly testable (with known delay values), the target pat...
This paper develops new techniques for detecting both stuck-open faults and resistive open faults, which result in increased delays along some paths. The improved detection of CMO...
1 This paper addresses the problem of testing path delay faults in a microprocessor using instructions. It is observed that a structurally testable path (i.e., a path testable thro...
A low overhead DFT technique, called clock-grouping, for delay testing of sequential synchronous circuits is presented. The proposed technique increases robust path delay fault co...
This paper presents a case-study of delay defect screening applied to Fujitsu 2.16GHz SPARC64 microprocessor. A nonrobust delay test is used while each test vector is compacted to...
