摘　　要：针对电路故障测试过程中存在故障难以定位和修复的问题,提出了一种基于功能重构的故障修复方法。该方法使用全集测试集对被测电路进行精确测试,以测试向量中的响应值与实际电路中的响应结果进行对比,实现对故障的精确定位。当被测电路的所有故障信息被收集后,采用功能重构的原理对出现故障的电路进行修复,在实现功能修复同时,降低了故障修复难度。文章给出了这种故障检测与功能重构的总体实现框图,并分别对模拟电路和数字电路的故障详细阐述了功能重构的方法。To deal with the problem of hard to locate circuit faulty and repair in the electric circuit failure test process,has proposed one kind of fault repairing method based on the function restructuring.This method uses the whole test collection to precise test the electric circuit.Has compare with the tests vector n the response value and the actual electric circuit response result to find the fault points.When has collected all of the breakdown information of the electric circuit,repaired the electric circuit by the function restructuring principle.While realizes the function repair,has reduced the fault repairing difficulty.The paper has given this kind of failure detection and the function restructuring the overall realizing diagram,and separately elaborated the function restructuring method in detail to the analogous circuit and digital circuit breakdown.
