【摘要】 在对可观测性无关项相关问题进行研究的基础上,通过计算逻辑网络中门的可观测无关项,得到最大允许函数集,依此来消除网络中冗余门,进行逻辑设计优化。同时对已有算法做了一定改进,给出了SANDTNT算法,以适用大输入和输出变量逻辑网络的优化。更多还原

【Abstract】 Study the observability of don’t care sets and pro pose a method for multilevel logic optimization through calculating the observab le don’t care sets at the gates in a network. The maximum sets of permissible fu nctions can be derived. Consequently an improved method for the design of large- scale integrated circuits is developed.更多还原
