文档介绍：基于Multisim的数字时钟的设计及仿真
摘要
随着电子设计自动化(EDA)技术的发展,开创了利用“虚拟仪器”、“虚拟器件”在计算机上进行电子电路设计和实验的新方法。Multisim就是一种能够运用这种新方法的软件,因它直观、便捷的特点使其在电子设计中具有广泛的应用。可以在Multisim软件中进行模拟仿真,避免了实际操作的繁杂和不便,同时节约了实验器材,有助于边学边用,从而学以致用。而数字时钟具有走时精确、校时方便、设计和使用简单的特点,能实现定时和报时功能,得到了广泛使用。通过这个数字时钟的仿真,帮助认识其软件作用,深入分析其原理,帮助了解数字时钟工作原理。
对于Multisim软件进行数字时钟的设计和仿真。我们首先在Multisim软件中创建好数字时钟的总电路图。然后用该软件中的仿真功能进行仿真。正确仿真的数字时钟应具有“秒”、“分”、“时”的十进制数字显示,能够随时校正分钟和小时,当时钟到整点时能够进行整点报时,还能够进行定时设置。

Abstract
Along with the development of Electronic Design Automation(EDA),a new way of the electronic circuit design and experiments is created by using virtual instruments ponents is a software to be able to use this way, because of its intuitive and convenient features of its electronic design with a wide range of applications. Multisim software can be carried out in the simulation, the actual operation to avoid the inconvenience of plicated and, at the same time to save the experimental equipment, help to learn, and thus apply what they have learned. And go figure, when the clock has precision, school and convenient design and easy to use features, to achieve timing and time functions, have been widely used. Through this figure the simulation clock to help recognize the role of its software, in-depth analysis of its principles, to help understand the working principle of the digital clock.
For design and simulation with Multisim software in the digital clock. We first created Multisim software digital clock circuit diagram of the total. And then use the software's simulation features in the simulation. Correct simulation of the digital clock should have "seconds", "sub", "when" the decimal figures, can be corrected at any time minutes and hours, when the bell when the whole point to carry out the whole time, but also can be set from time to time.
