本文叙述了对于有扇出的多输出组合电路进行误差检测的一般方法,详细地讨论了这种方法的误差检测特性,任何组合电路的输出误差都可预测,因而整个电路可设计成对于任何单固定故障为完全自检的。
This paper describes a general method for error detection of fan-out multi-output combinational circuits. The error detection characteristics of this method are discussed in detail. The output error of any combinational circuit can be predicted. Therefore, the whole circuit can be designed for any single Fixed fault is fully self-test.
