  • The switch circuit was modeled by graph theory model. The function edge and the switch edge were two important factors in the sneak circuit analysis. The two states of edge were represented by the edge state variable.The characters of the interface in the circuit were studied and the sneak circuit analysis was simplified. The relationships between the function edge and the switch edge were showed by changing the standard format of the switch function. The number of the system functions and the methods of function realized were obtained. Whether there were sneak circuits which influence the design functions in the system were determined by using the comparison between the numbers in the design circuit and the actual circuit. The position of the sneak circuit can be known by analyzing the actual circuits in different combination of switches. The sneak circuit problem was found when use this method to analyze the typical sneak circuit example. The results show this method can be used to analyze the sneak problem quickly and effectively at engineering analyses.
