Method and circuit for credible design of integrated circuit design process

Abstract

The invention discloses a method and a circuit for credible design of an integrated circuit design process. The method comprises the following steps: acquiring a gate-level netlist of an integrated circuit; wherein the integrated circuit gate-level netlist comprises process deviation information; acquiring a to-be-tested path in the integrated circuit; configuring the to-be-measured path into a ring oscillator; adding a gate-level netlist of an on-chip detection circuit in the gate-level netlist of the integrated circuit to complete the layout design of a new circuit; performing first dynamicsimulation on the new circuit to obtain a frequency threshold range of the ring oscillator; and performing credible design verification on the new circuit by utilizing the detection circuit accordingto the frequency threshold range. According to the credible design method provided by the invention, the influence of the Trojan horse on the side channel information is directly reflected on the pathdelay, so that the process of modeling the Trojan horse is omitted, and the test difficulty is reduced; and meanwhile, the detection circuit is simple in structure and easy to integrate into an integrated circuit design process, so that the measurement accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a method and circuit for credible design of an integrated circuit design process. Background technique [0002] In recent years, hardware manufacturers have widely used the business model of manufacturing equipment outsourcing and third-party intellectual property core (3PIP) procurement. However it results in highly complex supply chains involving thousands of people, as well as complex automated design and manufacturing equipment. In this mode, hardware attackers can more easily carry out attacks at different nodes in the supply chain. This breach of supply chain security can lead to malicious modification of integrated circuits (ICs), known as hardware Trojan horses (HTH). Hardware Trojans are stealthy in nature, designed to evade design verification and post-manufacturing testing. Activation of a hardware Trojan can cause catastrophic damage to the ...

Problems solved by technology

[0004] However, the existing monitors for current detection are generally composed of analog circuits, which require the addition of an analog-to-digital converter. At the same time, most of the existing Trojan horse detection methods need to model the Trojan horse, resulting in an excessive monitor circuit. The scale and complexity make the circuit not easy to integrate; in addition, the analog circuit is also more susceptible to process variation, which in turn affects the measurement results
