Hardware Trojans are intrusive actions that tend to corrupt the functional behavior of genuine designs, leak their sensitive information, or even downgrade their performance. This paper proposes a Computer-Aided Design (CAD) tool for Fragile Hierarchical FSM Watermarking to be employed as a novel presilicon Trojan detection technique at the RTL level. The performance of the proposed watermarking tool, regarding its complexity and insertion time overhead, is evaluated. Moreover, an intentional Trojan insertion scenario is executed in order to verify the sensitivity and reliability of the presented tool against the least changes in the original RTL design.
