1、沈阳理工大学学士学位论文摘要如今电子技术获得了飞速的发展,在其推动下,电子产品几乎渗透到社会的各个领域,有力地推动了社会生产的发展,同时也使现代电子产品性能进一步提高,产品更新换代节奏加快。EDA技术在进入21世纪后,得到了很大的发展,其基本特征是采用高级语言描述,具有系统仿真和综合能力。其VHDL语言设计的源文件,可以采用类似于C语言书写形式,并使用结构设计方法。本文从现代信息社会的现状、需要及未来的发展趋势出发,对EDA这一目前流行的电子设计技术进行了深入的研究,结合科研和教学实例,研究它的应用。描述了
2、VHDL语言及其基本特点,讨论了VHDL语言在EDA中的诸多优点,对QuartusII开发软件做了基本介绍。简述了Cyclone系列可编程逻辑器件的结构和功能。本设计采用VHDL语言完成了异步通信接口的设计。VHDL是一种硬件电路语言,可以利用VHDL语言来设计数字芯片,来完成各项功能。在通信中,常常要进行数据的传输,数据的串并变换等等,用VHDL语言实现很方便。异步通信接口是用来接收和发送数据帧的,可分为接受部分(用于接受数据)和发送部分(用于发送数据)。关键词:VHDL;QuartusII;异步通信;接
