Detection and Location of Hardware Trojans Using Path Delays

The IC industry transition to a decentralized and outsourced business strategy, wherein design, inclusion, production,
packaging, testing, and assembly are being performed by numerous firms around the world, must have generated issues
pertaining to IP rights piracy, reverse engineering threats on IC netlists as well as layouts, cloning of ICs, and detecting deceptive chips and also Hardware Trojans (HT). Threats posed by the injection of HTs have developed as a major issue for different vendors, governmental entities, and their vendors. This paper offers a new strategy for identifying HT using path-delay- dependent parametric techniques. The key advantage of this technique is that there is no requirement to compare the HT-inserted
circuit to the golden reference circuit. The proposed method has been implemented in 4-bit RCA for detecting and locating the HTs.
