摘要
EWB(Electronics Workbench)是一款方便快捷、功能强大的仿真软件。文章详细介绍了一种利用4518芯片设计数字钟的方法。首次设计出能顺次显示"123456日"的星期计数电路,并用EWB软件进行了仿真,取得了理想的效果。系统主要由振荡器,分频器,计数器,LED显示电路和报时电路组成。最后,本文还介绍了一种具有创新性的星期显示电路。
EWB （Electronics Workbench） is a convenient and powerful simulation software. The paper introduces a method for using chip 4518 to design digital electronic clock. A week days counting circuit for sequentially displaying ＂1234567＂ is designed firstly. The simulation is implemented with EWB software and the result is rather satisfactory. The system consists of oscillator, frequency-divider, number counter, LED display circuit, and chirping circuit. Additionally, an initiative design of week counting and displaying circuit is introduced in the paper.
