Researchers at the University of Wisconsin–Madison and Marist University have published a technical paper titled “Demystifying Gate-Level Localization of RTL Trojans.” The work focuses on detecting hardware Trojans in synthesized gate-level netlists, a key step for securing chip supply chains.
According to the paper’s abstract, RTL Trojans exhibit stable structural and signal-flow patterns. This suggests that malicious logic inserted at the register-transfer level retains identifiable characteristics even after synthesis into a gate-level netlist, potentially enabling more reliable localization.
The findings come from a single source, Semiconductor Engineering, and no specific detection methodology or experimental results beyond the abstract excerpt are described. Still, the observation of stable patterns offers a promising direction for automated Trojan detection in complex designs.
