The threat of inserting malicious logic in hardware design is increasing as the digital supply chains are becoming more deep and span the whole globe. Ring oscillators (ROs) can be used to detect deviations of circuit operations due to changes of its layout caused by the insertion of a hardware Trojan horse (Trojan).
