Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] Such as figure 1 As shown, it is a schematic flow diagram of an embodiment of the design method of the integrated circuit of the present invention, including steps:

[0025] Step S101: Obtain the register transfer level code of the initial integrated circuit design;

[0026] The register transfer level (RTL) code is obtained from the original integrated circuit design, which is generally described in VerilogHDL or VHDL language.

[0027] Step S102: Determine the node positions of potential hardware Trojan implants in the initial integrated circuit design according to the code;

[0028] In order to achieve a concealed effect, hardware Trojans often use nodes with very low activity inside the circuit as their trigger conditions, making it difficult to be activated and...

Abstract

The invention relates to a design method of an integrated circuit and a hardware trojan detection method. The design method comprises the following steps of acquiring a code of a register transfer level of an initial integrated circuit design; confirming a node position embedded by a potential hardware Trojan in the initial integrated circuit design according to the code; simulating the initial integrated circuit design to obtain a simulating circuit; computing the logic value probability of an interconnection line of the node position in the simulating circuit, and carrying out insertion design of testability circuits on the interconnection line of the node position according to the logic value probability; sequentially connecting the testability circuits in the simulating circuit to form a scan chain, and acquiring a new integrated circuit design according to the simulating circuit with the scan chain, wherein the scan chain is used for detecting the position of the hardware trojan of the integrated circuit according to the input test signals and the output results. According to the integrated circuit designed by the scheme of the invention, the position of the hardware trojan can be found, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an integrated circuit design method and a hardware Trojan horse detection method. Background technique [0002] With the development of integrated circuit technology and the intelligence of information systems, integrated circuit information security has gradually become the focus of attention. The current design and manufacturing process of advanced integrated circuits involves many uncontrolled links, such as: using a large number of third-party IP cores, outsourcing the manufacturing process to professional chip foundries, and using EDA design software provided by third-party suppliers. These current situations have greatly weakened the control of IC designers over the design and manufacturing process, making integrated circuits more and more vulnerable to sabotage and malicious modification by opponents during the design or manufacturing stage. Some additional ma...
