反馈置数法与反馈清零法仿真分析

Simulation analysis of feedback number setting method and feedback clearing method

数字电子技术是电子信息类专业重要的专业基础课,EDA软件辅助数字电子技术课程教学是发展趋势。利用Quartus Ⅱ软件,以74160十进制加法计数器芯片为例,采用原理图输入设计方法,分别用反馈置数法和反馈清零法设计了24进制计数器并进行了仿真分析。结果表明:将仿真软件应用到数字电子技术实验教学中,能直观演示出复杂抽象的设计思想,对提高学生学习效果、激发学生学习兴趣有重要的意义。

Digital electronic technology is an important professional basic course of electronic information specialties. Using EDA software of digital electronic technology course teaching is the trend of development. In this paper, by using Quartus Ⅱ software, taking 74160 decimal addition counter chip as an example, using Quartus Ⅱ schematic diagram design method, the 24 binary counter are designed and simulated using feedback number setting method and feedback clearing method respectively. The results showed that： the application of simulation software to the digital electronic technology teaching can intuitively demonstrate the design idea of complex abstract. It is significant to improve the learning effect of students and stimulate students＇ interest in learning.
