A Novel ATPG Method to Increase Activation Probability of Hardware Trojan

A hardware Trojan is defined as a malicious, undesired modification hidden in an electronic circuit. Since the logic test has the advantage of being free of process fluctuations and test noise, a logic test is used to test whether the circuit under test contains a hardware Trojan. This paper optimizes N-detect ATPG detection scheme to generate optimized test vectors for logic testing. The simulation results on s5378 and s38417 benchmarks demonstrate that, compared with traditional logic test technique, the test vectors generated by this paper are able to successfully increase activation probability of a hardware Trojan and detect abnormal outputs.
