A Method of Obtaining ASIC Schematic Using Scan Chain
Xiaoming Chen, Yang Liu, Songsong Li · Advances in computer science research · 2015
Hardware Trojan is easy to be embedded during IC's design and manufacturing.Mostly used Trojan detection technique based on side-channel approach need a Trojan-free instance, and could not ensure Trojan-free instance's consistent of schematic.With the help of scan chain, one of the widely used design for testability (DFT) technology, a novel approach is proposed to obtain the schematic of Application Specific Integrated Circuit (ASIC).It is verified and tested by formal verification and hardware simulation.This approach not only could help to obtain the Trojan-free instance which has the same schematic as the ordinary design, but also provide a new method to other Hardware Trojan detection techniques.
