一套完整通用的逻辑电路计算机辅助分析方法,可以解决工程设计中对逻辑电路的模拟和分析,减少人工分析的时间,提高工作效率。本文着重介绍一种逻辑组合电路计算机辅助分析的通用程序,用迅速简便的方法在普通计算机上实现,奠定逻辑电路计算机辅助设计的基础。一、逻辑关系式和信息符号的建立实现逻辑组合电路计算机辅助分析方法的关键,不仅要建立高级语言所能执行的逻辑表达式,而且还要建立相适应的能判别什么样的逻辑门、信号传递路径等计算机所需要的信息,让计算机自动完成一切“智能”工作。因此,我们首先用表1给出高级语言的逻辑表达式和辨别逻辑门的信息符号。
A complete set of common logic circuits Computer-aided analysis methods can solve the engineering design of the logic circuit simulation and analysis, reduce manual analysis time, improve work efficiency. This article focuses on a logic combination circuit of computer-aided analysis of general procedures, using a quick and easy method to achieve in ordinary computers, laying the foundation for computer-aided design of logic circuits. First, the establishment of logical relations and information symbols Logical combination circuit to achieve computer-aided analysis of the key not only to establish a high-level language can perform the logic expression, but also to establish appropriate to determine what kind of logic gate, the signal Pass the path and other information required by the computer, so that the computer automatically do all “smart” work. Therefore, we first use Table 1 gives the logic expressions of high-level language and information symbols to identify logic gates.
