Stage: Production and Test
In order to ensure trusted in–field operation of integrated circuits, it is important to develop efficient low–cost techniques to detect malicious tampering (also referred to as Hardware Trojan) that causes an undesired change in functional behavior.
Conventional post-manufacturing testing, test generation algorithms and test coverage metrics cannot be readily extended to hardware Trojan detection.
MERO is a statistical test generation tool written in C for generating a corpus of logic test patterns aimed at maximizing the Trigger and Trojan Coverage of a sampled potential Trojan population for a given gate-level design. MERO uses N-detect testing to ensure each Trojan from the sampled Trojan population can be triggered at least N times. The resulting test patterns can be used to detect potential Trojans after design fabrication through functional testing.
