| 摘要: |
| 本文针对线性模拟电路, 提出了一种基于系统状态变量的BIST 方法。该方法将系统的状态、状态变化率及输入信号进行加权求和, 以此加权和作为系统的故障检测输出。将其值的大小作为判别依据, 可以区分系统的正常与异常状态。此方法具有简单可靠, 故障覆盖率高的特点。 |

| Abstract: |
| For the linear analog circuits, a BIST method based on the system's state variables is presented. This method adds up the state variables, their variation speed and input signal by weights, uses the sum as the fault detection output of the system. The normal situation and abnormal situation can be distinguished by the magnitude of the output. This method is simple and reliable, and has a high fault coverage. |
