Abstract: | 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. |
