基于EWB软件的可扩展数字电子时钟设计

摘要

The EWB software is liking electronic circuit design staff, because of it’s visual image,graphic design, complete function, with circuit simulation function good, is nowadaysone of the most popular EDA design software.In this paper, the problem for electronic design engineers often encountered in the design of the circuit.Useing EWD software ,a 24-hour electronic clock with time adjust function and alarm clock function is designed.Details implement the design principles of digital electronics modules with specific circuit, pointed out the existence of inadequate design and improvement program.%EWB软件形象直观、电路设计图形化、功能齐全，具有良好的电路仿真功能，是时下最流行的的EDA设计软件之一，受到电子电路设计人员的喜欢。本文针对电子设计工程师在设计电路中常遇到的问题，基于EWB软件设计平台，设计可实现24小时调时、定闹钟功能的数字电子时钟，详细介绍数字电子中个模块的设计原理与具体电路的实现，指出设计存在的不足与完善的方案。
