基本数字时序电路Spice宏模型的建立

Building the Basic Digital Sequence Circuit Macro-Model in Spice

提出了在SPICE中建立数字时序电路宏模型的新方法。模型主要由受控源搭建而成,结构简单、仿真速度快,并且精度高,在SPICE仿真中大量用到,有良好的应用价值。文中主要讨论常用时序逻辑模型(D锁存器、D触发器和T触发器)的建立。

A new method of developing digital sequence circuit macro - models in SPICE is proposed in this article. The macro- models are mainly made up of the controlled sources and passive components. This article mainly discusses the building of such sequence logic models as D_ latch, D_FF and T_FF.
