对时序逻辑电路自启动设计的探讨

On the Design of Self-starting in a Sequential Logical Circuit

随着数字集成电路的广泛应用,我们在设计电路时,有时会遇到电路不能自启动问题。当电路不能自启动时,一般是不能应用于生产实践中的,而必须对电路进行修改。修改电路自启动的方法比较灵活,不同的修改方法,所得到的状态方程组是不一样的。本文在这里分析了电路不能自启动产生的原因,并介绍了修改电路自启动的一种方法。

Sometimes it is happed in a circuit design that it can＇t self-start. Generally a not self-starting circuit can＇t be applied in practice or production. It must be revised. There are many methods with different state equations to revise it. Reasons why a circuit can＇t self-start are analyzed in this article, while a method to revise it is provided.
