摘要
本文提出了一种基于动态电流-静态电流(Iddt-Iddq)的检测方法,在电路设计阶段插入扫描链进行分区设计相结合的硬件木马检测技术,选用Can总线控制器电路作为实验电路,在电路设计阶段将电路分区并插入扫描链,然后进行流片,选用源表、专用PCB测试板、Can总线收发器搭建测试平台进行芯片实测,实测结果表明,这种检测方法可以大幅减小工艺漂移的影响并且提高硬件木马检测分辨率.
In this paper, we propose a new detecting technology which combines the dynamic current-static current detecting approach in the test phase with inserting the scan-chain in the design phase. Choosing the Can Bus controller circuit as the circuit under test(CUT) , inserting the scan-chain in the design phase and tape it out. Then design specified PCB test board, choose the SourceMeter and Can transceivers to set up the test system. The test result shows that this system can reduce the influence of the process variation on the detecting result efficiently and improve the detection accuracy.
