Pspice在脉冲异步时序电路分析中的应用

The Application of PSPICE for Pulse Nonsynchronous Sequential Circuit Analysis

在分析脉冲异步时序电路时，考虑到不同类型、不同系列逻辑器件的实际延时，分析起来就比较复杂与繁琐，往往容易出错。但是，在采用Ｐｓｐｉｃｅ程序进行计算机仿真分析时，可以设定实际器件的不同延时，用波形图进行分析，既简单又直观，不会出错。

When pulse nonsynchronous seqquential circuit is analyzed, because of practical delay of various type and different series of logic devices, analysis will be very complex and heavy, and errors often occur. However When simulation analysis with PSPICE program for drawing waveshape diagrams is adopted, we can set up different delays for devices involved. It is simple, visual and error-free.
