VHDL的优化与检测
摘要:在电子技术设计领域，可编程逻辑器件（PLD）的应用，已有了很好的普及性。这些器件为数字系统的设计带来极大的灵活性。由于该器件可以通过软件编程而对其硬件的结构和工作方式进行重构，使得硬件的设计如同软件设计那样方便快捷。这一切极大地改变了传统的数字系统设计方法，设计过程甚至设计观念。从应用的广度和深度来说，由于电子信息领域的全面数字化，基于EDA的数字系统的设计技术具有更大的应用市场和更紧迫的需求性。
EDA要求用硬件描述语言, （HDL）来描述硬件电路的了行为和功能。作为IEEE的标准语言，VHDL在范围内*国家的电子系统设计领域获得广泛应用。本论文就是通过VHDL的各种优化设计，仿真，VHDL的实现来介绍VHDL的基本概念，特点，应用及优化过程。

VHDL Optimization and Examination
Abstract:In technology electron field, the using of programme,logic device is getted good gain ground. Those parts of an apparatus bring huge agility for digit systems design Because these device can compose the structure and working of the hardware again by software programme, it make the design of hardware as convenient as the design of software.The whole shoot change maximumly the design way.design process,even design ideas of the conventional digit system,Saying flom the extent and depth of the applying,the design technology of digit system base on EDA take on more application market and more pressing demand.
EDA describing hardware circuits action and function HDL. As a standard language of IEEE, VHDL win abroad application in electron system design field of advance country in the seven seas. This paper introduced the basic concept, characters and appliance process of the VHDL by designing, simulating, and VHDL realization of all kinds of VHDL optimization
