I DDQ test has been used extensively both as defect reliability screen and as a defect diagnostic technique. However, the increase in subthreshold leakage currents in deep sub-micron technologies has reduced the effectiveness of I DDQ in these applications. Quiescent Signal Analysis (QSA) is a novel diagnostic technique that uses I DDQ measurements made at(More)
Hardware Trojans have emerged as a new threat to the security and trust of computing systems. Hardware Trojans are deliberate and malicious modifications to the logic function implemented within digital and mixed signal chips. In contrast to software Trojans, it is not possible to simply "scan the hard drive" to eradicate a hardware Trojan. Hardware Trojans(More)
