文章介绍了利用集成4位二进制计数器74LS163同步置位法构成任意进制计数器的设计方法,并进行了按自然态序计数、按逆排序计数、按任意排序计数的Multisim仿真设计,同时用不同颜色探针显示计数过程和计数结果,直观形象地描述出计数器的状态变化特点,分析了不同方法仿真结果的正确性,指出了Multisim中74LS163计数器时钟触发方式与实际芯片的不同。

This article introduces the method of forming arbitrary binary counter design with integrated 4 bit binary counter74LS163 synchronization method,and makes Multisim simulation design with natural state sequence counting,inverse sorting counting and any sort counting. The counting process and counting result are shown with different color probes,which describe vividly the characteristics of counter state changes,and analyze the accuracy of simulation results with different methods. Finally,this article points out the differences between actual chips and clock trigger mode of 74LS163 counter of Multisim simulation.
