摘要：It is an effective method to use qualitative reasoning theory to realize sneak circuit analysis (SCA). The method using qualitative modeling combined with functional simulation to realize sneak circuit analysis. The qualitative models of resistive element, switch, transistor, MOS pipe, digital devices, analog devices, mechanical devices and other types of components were established and the qualitative simulation process was studied. Self-developed QSCA software (qualitative simulation-based sneak circuit analysis) is applied to analyze typical cases and verify the technical correctness. The result shows that this method could provide technical support for the system to find sneak circuit problems at the early design stage and it can also be used in the field of fault modes and effects analysis.
