2、革新和与国外的交流，当今经济建设需求的各类电梯，几乎全部都可以在中国生产。电梯生产作为一门国家的新兴产业，它这种能有减少人口膨胀对环境所造成的巨大压力的特性，注定了其在中国具有一片光明的前景。本设计就是基于电子设计自动化（Electronic Design Automation）技术中的甚高速集成电路硬件描述语言（Very High Speed Integrated Circuit Hardware Descrisioon Language）语言所开发的三层电梯控制程序，实验调试平台是 Altera 公司的 QuartusII软件。本程序具有 VHDL 语言设计里最为常用的三个模块：实体 en
3、tity，对控制器的实体（输入输出）端口进行定义；结构体 architecture，对控制器内部的信号端进行定义；进程执行单元 process，对控制器的所有输入输出端口、内部信号端口进行功能、行为描述。通过程序调试及运行仿真，结果表明，本程序可以完成：电梯运行所在楼层指示、电梯运行方向指示、关门延时设置等。本设计对更高层的电梯控制设计具有一定的拓展性。关键词：关键词：电梯控制 程序设计 EDA VHDL QuartusIITitle The Lift Control Design Basic on the EDA TechnologyAbstract:2The lift , as the m
