According to the characteristics of asynchronous sequential circuits while clock signal is not synchronized,this paper leads in the commutation of clock variables,leading out the unified state equation of each toggle circuit to reference clock in circuits.
针对异步时序电路时钟信号不同步的特点,引入折算时钟变量,导出了电路中各触发器对基准时钟的统一状态方程,由此状态方程出发并按一定的步骤进行,能使异步时序电路的分析得到简化。
