摘要
 電子設(shè)計(jì)自動(dòng)化（EDA）是一種實(shí)現(xiàn)電子系統(tǒng)或電子產(chǎn)品自動(dòng)化設(shè)計(jì)的技術(shù)，它與電子技術(shù)、微電子技術(shù)的發(fā)展密切相關(guān)，它吸收了計(jì)算機(jī)科學(xué)領(lǐng)域的大多數(shù)最新研究成果，以高性能的計(jì)算機(jī)作為工作平臺(tái)，促進(jìn)了工程發(fā)展。EDA的一個(gè)重要特征是使用硬件描述語(yǔ)言（HDL）來(lái)完成設(shè)計(jì)。超高速硬件描述語(yǔ)言（VHDL）是經(jīng)IEEE和美國(guó)國(guó)防部確認(rèn)的標(biāo)準(zhǔn)硬件描述語(yǔ)言，自IEEE公布了VHDL的標(biāo)準(zhǔn)版本，IEEE-1076之后，各EDA公司相繼推出了自己的VHDL設(shè)計(jì)環(huán)境，或宣布自己的設(shè)計(jì)工具可以和VHDL接口。此后VHDL逐步取代了原有的非標(biāo)準(zhǔn)的硬件描述語(yǔ)言。1993年，IEEE對(duì)VHDL進(jìn)行了修訂，從更高的抽象層次和系統(tǒng)描述能力上擴(kuò)展VHDL的內(nèi)容。本文介紹了基于VHDL語(yǔ)言實(shí)現(xiàn)的電梯控制系統(tǒng)的設(shè)計(jì)，使用了狀態(tài)機(jī)，并進(jìn)行了軟件和實(shí)驗(yàn)平臺(tái)的仿真。該控制系統(tǒng)遵循方向優(yōu)先的原則，提供樓層用戶的載客服務(wù)并指示電梯的運(yùn)行情況。說(shuō)明了用VHDL 語(yǔ)言設(shè)計(jì)數(shù)字電路的方法以及VHDL 語(yǔ)言在數(shù)字電路設(shè)計(jì)仿真中的重要作用, 仿真結(jié)果表明VHDL 語(yǔ)言應(yīng)用于數(shù)字電路仿真是切實(shí)可行的，該語(yǔ)言在電子設(shè)計(jì)領(lǐng)域受到了廣泛的接受。

ABSTRACT
 Electronic design automation (EDA) is a realization of an electronic system or electronic design automation products of technology, with electronic technology, microelectronic technology is closely related to the development, it has absorbed most of the field of computer science and the latest research results, as a high-performance computer Working platform to promote the development of the project. EDA is an important feature of the use of hardware description language (HDL) to complete the design. Super-high-speed hardware description language (VHDL) is the IEEE and the U.S. Department of Defense confirmed the standard hardware description language, since the publication of the IEEE VHDL version of the standard, IEEE-1076, the EDA companies have launched their own VHDL design environment, or to be declared Their design tools and VHDL interface. Since then VHDL gradually replace the original non-standard hardware description language. 1993, IEEE on VHDL was revised from a higher level of abstraction and system capacity expansion VHDL description of the contents. In this paper, based on VHDL language of the elevator control system design, the use of the state machine and a software platform for simulation and experiment. The control system to follow the direction of the principle of giving priority to provide the passenger service users floors and directed the operation of the lift. Note the use of VHDL digital circuit design methods and VHDL in digital circuit design to the important role of simulation, simulation results show that the VHDL language used in digital circuit simulation is practicable, the language in the field of electronic design has been widely accepted.
