VHDL的優(yōu)化與檢測(cè)
摘要:在電子技術(shù)設(shè)計(jì)領(lǐng)域，可編程邏輯器件（PLD）的應(yīng)用，已有了很好的普及性。這些器件為數(shù)字系統(tǒng)的設(shè)計(jì)帶來(lái)極大的靈活性。由于該器件可以通過(guò)軟件編程而對(duì)其硬件的結(jié)構(gòu)和工作方式進(jìn)行重構(gòu)，使得硬件的設(shè)計(jì)如同軟件設(shè)計(jì)那樣方便快捷。這一切極大地改變了傳統(tǒng)的數(shù)字系統(tǒng)設(shè)計(jì)方法，設(shè)計(jì)過(guò)程甚至設(shè)計(jì)觀念。從應(yīng)用的廣度和深度來(lái)說(shuō)，由于電子信息領(lǐng)域的全面數(shù)字化，基于EDA的數(shù)字系統(tǒng)的設(shè)計(jì)技術(shù)具有更大的應(yīng)用市場(chǎng)和更緊迫的需求性。
EDA要求用硬件描述語(yǔ)言, （HDL）來(lái)描述硬件電路的了行為和功能。作為IEEE的標(biāo)準(zhǔn)語(yǔ)言，VHDL在范圍內(nèi)*國(guó)家的電子系統(tǒng)設(shè)計(jì)領(lǐng)域獲得廣泛應(yīng)用。本論文就是通過(guò)VHDL的各種優(yōu)化設(shè)計(jì)，仿真，VHDL的實(shí)現(xiàn)來(lái)介紹VHDL的基本概念，特點(diǎn)，應(yīng)用及優(yōu)化過(guò)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
