| 摘 要： | 为判断给定系统是否存在潜在通路,研究了潜在通路存在的判定方法.用图论模型对电路建模,利用图论的邻接矩阵找到在某一开关组合状态下电源到地的所有路径,通过路径和功能之间的一一对应关系确定电路实现的功能数.提出了一种求短路屏蔽路径数算法,可以求得短路屏蔽的功能数.通过比较在某一开关状态下的设计功能数和实现的功能数,确定是否存在潜在通路以及潜在通路存在数目.仿真实例验证了方法的有效性.

| Abstract: | A method for determining whether sneak circuits exist in circuits is proposed.Circuits are modeled with graph theory model.The number of paths of the circuits can be discovered by using adjoining matrix of graph theory model under certain combination of switches.Implemented number of functions of circuit can be determined by the relations between paths and functions.The algorithm of acquiring the number of shielding paths by short circuit is presented.Comparison between number of implemented functions and d... |
