摘要
在时序逻辑电路的分析或设计过程中,都存在自启动的确认环节.以扭环形计数器的自启动电路设计为例,提出一种基于自定义多变量卡诺图的自启动研究方法,分析了电路没有自启动功能的原因所在,并利用卡诺图具有的化简能力,精简优化自启动电路设计.5变量以上的多变量卡诺图应用,使此方法具有更强的工程实用性.同时,此方法可推广到其他类型时序逻辑电路自启动功能的分析、设计工作中.
Abstract
In the process of analysis and design of sequential logic circuit,the self-starting validation step is required.By taking the self-starting circuit design scheme of Johnson counter as an example,a self-starting research method based on custom multivariable Karnaugh map is proposed.The reason of no self-starting function in circuit is analyzed,and the design of self-starting circuit is optimized by using the simplification ability of Karnaugh map.The application of Karnaugh map with more than 5 variables makes the method more practical in engineering.At the same time,the proposed method can be extended to the self-starting analysis and design of other type of sequential logic circuits.
