A Self-starting Method Based on Multivariable Karnaugh Map
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.
