关于逻辑函数化简的计算机辅助设计

Computer-Aided Design for the Simplification of Logical Functions

本文针对用代数法,图解法进行逻辑函数化简的缺点,提出了利用电子计算机进行辅助设计。文中给出了关于五个变量化简的源程序,其主要特点:当存在竞争冒险时,该程序将自动引入校正信号,以消除竞争冒险.从而保证了付诸实际逻辑网络时速度独立(Speedind ependent).源程序已在IBM PC/XT机上调试通过.

In accordance with the shortcomings of algebraic method and graphic method which are used to simplify logical functions, computer aided design is advanced. A source program for the simplification about five variables is given in this paper. The characteristic of the program is, when competitive risk exists it will draw a correction signal to eliminate the risk and make the speed independent when it is put into the practical logical net. This source program has been debugged and passed in IBM PC/XT computer
