奇偶校验电路设计
一、 实验目的
1(熟悉QuartusII的使用;
2. 学习在QuartusII中;
3. 学习原理图方式自定义元件的输入，封装，调用; 4. 掌握奇偶校验原理;
5. 学会使用现成的芯片搭建目标电路。
二、 实验内容和原理
实验内容:
(1)在QuartusII环境下以原理图方式建立顶层文件工程 。利用多个74386芯片搭建一个奇偶校验电路。74386提供四个2输入异或门
(2)建立仿真文件，观察输出结果。
实验原理:
奇偶校验码是最简单的数据校验码，其码距为2，可以检测出 一位错误，但无法指出错误的位置。

方法

为将有效信息位和校验位读入，判断其1的个数是奇数个还是偶数个，在奇校验的情况下正常情况下个数应该为奇数个，偶校验正常情况下应该是偶数个。
校验码的生成:对于奇校验，判断有效信息位1的个数，若为偶数则校验位为1，奇数则校验位为0;偶校验反之。

达式如下:
good processing performance, with sufficient rigidity. Template selected template surface should be flat and smooth, plywood coated high strength, good wear resistance, water resistance, durability, physical and chemical properties of stable and smooth surface, no pollution, no damage, clean. Template straight keel, specifications, and panels close, firmly attached, have sufficient rigidity. Templates may not play the ink, paint and write numbers to avoid contamination of concrete surfaces. Template design set of bolt holes through walls, but not free to play holes, openings, portrayal, nailing. Release agent used on concrete surface quality and color does not affect the release agent. Pull bolt specifications and varieties should be according to the concrete lateral pressure, wall waterproofing, air defence requirements and template Panel selection, bolts used should have sufficient strength to pull the bolt casing and plug should be determined according to the diameter of the bolt, the choice of plastics, rubber, nylon and other materials. Topstitching cross-section according to the circumstances, the request can tear down, should adopt the trapezoid, square, rounded square; can be made for hardwood, nylon, plastic, aluminum, stainless steel and other materials. Depth is not greater than 20mm. Steel frame in front of the Assembly must be straightened, wood joist requires that you have sufficient rigidity. Keel as far as possible without joints, if it proves necessary to connect, the connection must be staggered. Template processing must be carried out in wood processing plant, processing materials when cutting line cutting, precise size, angle, surface smooth, tight joints. Field spell using a template before the template, on the surface smoothness, the section size, Yin and Yang template angle, adjacent to surface level and check the bolt Assembly. Before clamping, to check the template, especially the template Panel connection

说明:波形信息位为奇数个1，校验位为0时，输出的奇校验
位为0，偶校验位为1，奇校验错误为0，偶校验错误为1(即有
错)。同理其他测试分别测试了信息位为奇数个1，校验位为1、
信息位为偶数个1，校验位为1、信息位为偶数个1，校验位为0
的情况，图中波形的测试完全符合预期要求。
