模拟电路故障字典自动生成仿真平台的建立

Based on the developed hard fault (open and short faults) dictionary auto-generating framework for analog circuits, and combined the new research progress of the theory of soft fault diagnosis, we achieved the soft fault dictionary auto-generating, and established the unified framework of both hard and soft fault dictionary auto-generating for analog circuits. Based on the slope fault model and the linear relativity coefficient of node-voltage increments relation function fault model, we programmed to realize the auto-generating of single soft fault and double soft faults dictionary for analog circuits, and the modular soft fault dictionary auto-generating of closed-loop operational amplifier based analog circuits, too. This paper introduced the algorithm and theory of soft fault dictionary and structure of the simulation framework with detail, and finally simulation results of auto-generating fault dictionary of example circuits are given.
