时序逻辑电路的次态卡诺图分析法

A METHORD OF USING THE NEXT STATE KARNAUGH MAP TO ANALYSE THE SEQUENTIAL LOGIC CIRCUIT

讨论了同步时序逻辑电路的次态卡诺图分析法与异步时序逻辑电路的次态卡诺图分析法，这两种方法分别是利用状态方程给出各触发器的次态卡诺图，并由次态卡诺图画出状态转换图以及利用状态方程和时钟方程绘出包含“动令”在内的各触发器的次态卡诺图，并由次态卡诺图画出状态转换图．该法是１种分析时序逻辑电路功能的新方法．

The auther discusses the mothod of using the next state Karnaugh map to analyse the synchronous sequential logic circuit and the asynchronous sequential logic circuit.The former is to draw the next state Karnaugh map of each flip flop by the state equation and to work out state convert map according to the map;the latter is to draw the next state Karnaugh map of each flip flop including “commanding” by the state and clock equations and also to work out state convert map according to the map.This is a new way to analyse the function of sequential logic circuit.
