应用EDA技术实现汉字滚屏系统设计

The Realization of Chinese Characters Rolling on Screen System with EDA Technology

通过汉字滚屏系统的设计 ,详细介绍了如何使用硬件描述语言VHDL设计复杂逻辑电路的步骤和过程 ,以及应用美国ALTERA公司的MAX +PLUSⅡ软件进行系统设计及仿真的方法。通过设计 ,可以看到应用EDA技术进行系统设计、逻辑综合和模块仿真是数字系统设计的重要手段 ,也是电子电路设计方法上一次革命性的变化。

In this paper,the design of Chinese characters rolling on screen system was summarized.Especially,the process of how to use the hardware describing language VHDL to design the complex logic circuit was introduced.And the way about how to use the software of MAX+PLUSⅡ which is produced by ALTERA company of America for design and simulation was also given.From the process of the design,we pointed out that it was an important way for digital system to system design,logic synthesis and block simulation with EDA technology.It is also a revolutionary change of electronic circuit design.
