摘要
介绍了一种基于EDA工具——MAX+plus II的多功能数字时钟的设计。在设计了数字时钟的每一个单元电路:分频、计时、显示及整点报时电路之后下载到硬件实现。其设计巧妙结合文本、原理图两种输入方法,思路简洁、新颖,经验证系统功能可靠。
This article mainly introduces a method of multi - purpose digital clock based on MAX ＋ plus Ⅱ, which is a kind of EDA software.After each unit circuit of different functions such as frequency dividing,counting, displaying and integral point time reporting is finished, the design is downloaded to CPLD to realize. This paper adopts two kinds of input ways, text input and principle figure input. This design idea is succinct and novel. It is verified that its function is reliable.
