基于VHDL的乒乓球游戏电路设计 作者姓名： 专业名称：信息工 指导教师： 摘要 人类社会已进入到高度发达的信息化社会，信息社会的发展离不开电子产品的进步。现代电子产品在性能提高、复杂度增大的同时，价格却一直呈下降趋势，而且产品更新换代的步伐也越来越快，实现这种进步的主要原因就是生产制造技术和电子设计技术的发展。前者以微细加工技术为代表，目前已进展到深亚微米阶段，可以在几平方厘米的芯片上集成数千万个晶体管；后者的核心就是EDA技术。EDA是指以计算机为工作平台，融合了应用电子技术、计算机技术、智能化技术最新成果而研制成的电子CAD通用软件包，主要能辅助进行三方面的设计工作：IC设计,电子电路设计以及PCB设计。没有EDA技术的支持，想要完成上述超大规模集成电路的设计制造是不可想象的，反过来，生产制造技术的不断进步又必将对EDA技术提出新的要求。 本次设计的任务是设计一个基于VHDL语言的乒乓球游戏电路。我们采用EDA技术对核心电路进行设计，完成设计后把用VHDL描述的源程序下载到目标芯片上并对其功能进行仿真。电路设计平台采用的美国ALTERA公司的EDA软件--MAX+plusII。 该设计由模拟乒乓球行进路径的发光管亮灯控制模块(BALL),乒乓球板接球控制模块(BOARD),失球计数器的高位计数模块(COUT4), 失球计数器的低位计数模块(COUT10),乒乓球行进方向控制模块(MWAY),失球提示发声模块(SOUND)和总控制模块(BALLCTRL)七个模块组成。通过使用自顶向下的层次化的设计方法，实现了乒乓球游戏的所有功能。 关键词 : 乒乓球游戏 EDA VHDL MAX+plus II FPGA Abstract Society has already got into the height flourishing information-basedsociety, information society of the development can not get away from the progress of electronics product.Modern electronics product at the function raises, complications enlarge of in the meantime, but the price has been presenting to descend trend, and the product renewal change the step of generation also more and more quick, the main reason which carries out this kind of progress is to produce manufacturing technique and electronics to design a technical development.The former takes very small processing technology as to represent, having already made progress a deeply second micron stage currently, can at several square minimeter the chip of the rice up integrate few ten millions transistor;The core of the latter is an EDA technique.The EDA means to take calculator as work terrace, blending an applied electronics technique, calculator technique, intelligence to turn technique the last word but developing of the electronics CAD in general use softwarepackage, can Mankinds mainly lend support to a design work of carrying on three aspects:IC design, design and PCB design of the electronics electric circuit.There is no EDA technical support, the design manufacturing whi
