White box instrumentation FPGA prototype verification method for integrated circuit safety function

Abstract

The invention belongs to the technical field of integrated circuit design verification, and discloses a white box instrumentation FPGA prototype verification method for an integrated circuit safety function. The white box instrumentation FPGA prototype verification method comprises the steps: 1, selecting a white box instrumentation point of an FPGA prototype verification system according to a logic structure of an integrated circuit safety function protection module; 2, designing a white box pile inserting structure; 3, inserting the designed instrumentation structure into a white box instrumentation point of an FPGA prototype verification system, and performing macro definition on the instrumentation structure at the white box instrumentation point; 4, building a test platform; 5, generating test excitation; and 6, injecting the test excitation into the built test platform, and performing test verification. According to the white box instrumentation FPGA prototype verification method, the instrumentation code can run on the FPGA prototype without influencing the functions of the RTL, and the security of the integrated circuit can be visually reflected, i.e., the defense effect for the instrumentation hardware Trojan horse, the vulnerability or the backdoor is achieved.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit design verification, and in particular relates to a white-box FPGA prototype verification method for integrated circuit security functions. Background technique [0002] With the development of integrated circuits, the scale of the system on a chip is increasing day by day, and the system function modules are becoming more and more abundant. Many security functions are directly implemented at the hardware level. The huge design scale and complex functional applications make the design must be rigorous and compliant. The error or omission of the root connection may lead to the failure of tape-out, so the verification and testing of integrated circuits become very important, and the verification of integrated circuit security modules cannot be ignored. [0003] At present, more representative test verification methods include: functional verification based on UVM simulation verification p...
