目前设计时序电路大都是根据要求,选用一定类型的触发器,列出各触发器的真值表和激励表,再由状态转换求出驱动方程,利用卡诺图进行化简,写出简化逻辑式,最后画出逻辑图。这种方法对于解决较少变量的设计是行之有效的,但对多变量、多状态问题的设 At present, the design of sequential circuits are mostly based on the requirements, the choice of a certain type of flip-flop, lists the flip-flop truth table and incentive table, and then derived by the state transition drive equations, the use of Karnaugh map simplification, write simplified logic Style, and finally draw the logic diagram. This method is effective in solving the design of fewer variables, but for multivariable, multi-state problems
