硬件描述语言在数字系统设计中的应用

Apply VHDL to Digital System Design

硬件描述语言（VHDL）是数字系统高层设计的核心，是实现数字系统设计新方法的关键技术之一。本文介绍了硬件描述语言的功能特点，并通过彩灯控制系统的设计过程（给出了仿真结果），介绍应用硬件描述语言及自动综合系统以自顶向下的方法进行大规模数字系统设计的过程，揭示了硬件描述语言设计数字系统、逻辑综合和仿真等技术在数字系统设计中的重要地位和作用。

VHDL is considered as a core of digital system design and a key technique of imptement digital systems design. This paper first discusses the feature of VHDL ,and introduces the process of very long digital system by VHDL and auto-synthesis system with the method of Top-Down through designing control system of color lamp, reveals that it is very important to design digital system, logic synthesis and emulation with VHDL.
