3、程设计评分表.一、16选1选择器的主要功能数据选择器是常用的组合逻辑部件之一。它由组合逻辑电路对数字信号进行控制来完成比较复杂的逻辑功能。它有若干个数据输入端d0、d1、.，若干个控制输入端a0、a1，.和一个输出端y0。数据选择是指经过选择，把多个通道的数据传送到唯一的公共数据通道上去。它的功能相当于一个多个输入的单刀多掷开关.因此数据选择器又称多路转换器或多路开关。数据选择器(mux)的逻辑功能是在控制输入端加上适当的信号，既可从多个输入数据源中讲所需的数据信号选择出来，送到输出端。1. 函数真值表 输入输出abcde000000010010001101000101011001111000

5、已全部完成，能够完成预期的功能，在本课题的设计中体现了vhdl覆盖面广，描述能力强，是一个多层次的硬件描述语言及pld器件速度快，使用方便，便于修改等特点。由于时间有限和经验是平的欠缺，不足之处还望老师予以指正。在这一周里我们再次熟悉和增强了对vhdl语言的基本知识，熟悉利用vhdl语言对常用的的组合逻辑电路和时序逻辑电路编程，把编程和实际结合起来。vhdl硬件描述语言打破了硬件和软件设计人员之间互不干涉的界限，可以使用语言的形式来进行数字系统的硬件结构、行为的描述，直接设计数字电路硬件系统。通过编程、下载后，该芯片已经具备了原来需要使用复杂的数字电路实现的功能；更加了解和加深了对编制和调试程

6、序的技巧，进一步提高了上机动手能力，培养了使用设计综合电路的能力，养成了提供文档资料的习惯和规范编程的思想。本次的课程设计将各个单一的模块实现其功能后，学会通过原理图或顶层文件把各模块连接。课设注重的不仅是把理论知识巩固，而且应把理论和实际相结合，把知识应用到生活中。课设时间不长，要在短时间内完成绝非个人力量能达到的，要学会集众人之精华，还要善于利用已有的工具为己服务，开拓思维。课设让我们认识到所学本科知识的真正实用性，只是这门课开始研究的第一步。一、jk触发器的主要功能jk触发器是数字电路触发器中的一种电路单元。jk触发器具有置0、置1、保持和翻转功能，在各类集成触发器中，jk触发器的功能最

7、为齐全。在实际应用中，它不仅有很强的通用性，而且能灵活地转换其他类型的触发器。由jk触发器可以构成d触发器和t触发器。1. 特性方程2.真值表cpjk0xx000xx1110000100111010010110110011待添加的隐藏文字内容3101111101111103.逻辑电路图二、详细设计1.新建工程管理2. 输入文本语言程序进行编译3.编译成功，选择波形编辑器功能4.对应结点5.形成综合编译后网表三、进行程序仿真调试1.给定输入信号2.波形仿真测试成功3. 生成波形图四、心得体会总结 成了16选1选择器的电路设计之后，便开始了jk触发器的课题设计，因为前一个课设的完成，使我对于qua

8、rtus软件的使用有了一定的了解，所以在这个实验设计的时候也轻松了很多。在完成jk触发器的课设时，我只要参看书本上的jk触发器的设计思路完成源代码的编写即可，然后就是上机测试编写的程序，结果在测试时，出现了错误，但是在老师和同学的帮助下，我终于解决了它，然后编译、仿真。虽然第二个课设没有花费很多的时间，但是我还是发现，在实际设计中，仅仅拥有书本上的理论性知识是远远不够的，还要把知识与实际操作相结合，才能更加了解这门课程的精奥之处。课程设计结束了，但是从中学到的知识会让我受益终身。发现、提出、分析、解决问题和实践能力的提高都会受益于我在以后的学习、工作和生活中。在设计的过程中发现了自己的不足之处

9、，对以前所学过的知识理解得不够深刻，掌握得不够牢固。本次实验我对一些基本操作有了更好的掌握，对于数字逻辑电路的设计也有了更深刻的理解。本次实验老师都是要求独立完成。在这一点上很好的锻炼了我们的独立完成设计的能力。这是一次有意义实验。实验过程中我们遇到了很多困难然后再自己的努力下克服困难，让我们体会到的不仅是实验课程设计的乐趣，更让我们学会了怎样面对困难。我想自己在计算机方面的知识还远远不够，在今后的学习和生活中我会更加努力的不断学习吸取新的知识，注重知识和实践的结合。 最后，我们衷心的感谢课设期间一直指导和陪伴着我们的老师。五、附录1.16选1选择器源代码：library ieee;use i

32、an arm injection, or is a self-righteous spiritual.一个人的时候，自己的想法总是特别地清晰。想要的，不想要的，界限明确，好像没有什么可以撼动自己。也曾经好像已经下定了决心去做某件事，但更多的时候是最后又打起了退堂鼓。嫌恶过自己的怯懦，最终却发现有很多缘分，有很多错过，好像冥冥之中真的已经注定。那些曾经所谓的非做不可，只是青葱年华里自己给自己注射的一支强心剂，或者说，是自以为是的精神寄托罢了。at the moment, the sky is dark, the air is fresh factor after just rained. sud
