EDA习题第一章1。

1 EDA的英文全称是什么？EDA的中文含义是什么？答：EDA即Electronic Design Automation的缩写，直译为：电子设计自动化。

1.2 什么叫EDA技术？答：EDA技术有狭义和广义之分，狭义EDA技术就是以大规模可编程逻辑器件为设计载体，以硬件描述语言为系统逻辑描述的主要表达方式,以计算机、大规模可编程逻辑器件的开发软件及实验开发系统为设计工具，通过有关的开发软件，自动完成用软件的方式设计的电子系统到硬件系统的逻辑编译、逻辑化简、逻辑分割、逻辑综合及优化、逻辑布局布线、逻辑仿真，直至完成对于特定目标芯片的适配编译、逻辑映射、编程下载等工作,最终形成集成电子系统或专用集成芯片的一门新技术，或称为IES/ASIC自动设计技术.1。

3 利用EDA技术进行电子系统的设计有什么特点?答：①用软件的方式设计硬件;②用软件方式设计的系统到硬件系统的转换是由有关的开发软件自动完成的；③设计过程中可用有关软件进行各种仿真;④系统可现场编程,在线升级；⑤整个系统可集成在一个芯片上,体积小、功耗低、可靠性高。

1。

4 从使用的角度来讲,EDA技术主要包括几个方面的内容？这几个方面在整个电子系统的设计中分别起什么作用?答：EDA技术的学习主要应掌握四个方面的内容：①大规模可编程逻辑器件;②硬件描述语言;③软件开发工具；④实验开发系统.其中，硬件描述语言是重点。

对于大规模可编程逻辑器件，主要是了解其分类、基本结构、工作原理、各厂家产品的系列、性能指标以及如何选用，而对于各个产品的具体结构不必研究过细。

对于硬件描述语言,除了掌握基本语法规定外，更重要的是要理解VHDL的三个“精髓”:软件的强数据类型与硬件电路的惟一性、硬件行为的并行性决定了VHDL语言的并行性、软件仿真的顺序性与实际硬件行为的并行性;要掌握系统的分析与建模方法，能够将各种基本语法规定熟练地运用于自己的设计中。

对于软件开发工具，应熟练掌握从源程序的编辑、逻辑综合、逻辑适配以及各种仿真、硬件验证各步骤的使用.对于实验开发系统,主要能够根据自己所拥有的设备，熟练地进行硬件验证或变通地进行硬件验证。

Altera的命名规则如下：工艺+版本+型号+LE数量+封装+器件速度。

举例：EP2C20F484C6EP 工艺2C cyclone2 （S代表stratix。

A代表arria)20 2wLE数量F484 FBGA484pin 封装C6 八速数字越小速度越快。

那么首先：LE数量在同等器件信号的同时越多的越好。

同时越贵管脚数量在同等情况下越多越好。

器件速度越快越好。

FPGA可能没有先进性一说：不同产品不同用途。

cyclone系列：一共3代cyclone系列是FPGA的A版入门产品。

涵盖面广，而且对应的器件无论功耗和速度都不错。

在小规模设计上与xilinx的spartan3A竞争低端市场。

stratix：总共4代的stratix直瞄大规模。

数字信号处理以及片上系统等高端市场。

无论是器件速度还是内部资源都是全新的构架。

至于片上系统以及内部DSP，stratix4和高端xilinx vertix5成为了两大公司在高端市场的主流。

采用ispLSI1016芯片设计数控系统的位置板大连理工大学林乐忠王永青胡力耘摘要采用新型的大规模可编程集成芯片)))ispL SI1016设计数控系统中的位置板,与采用其它IC芯片设计的位置板相比,可改善整个位置环的逻辑和电气特性,对于提高整个数控系统的加工精度和可靠性,具有实用价值。

关键词:ispLSI1016计数器位置反馈Design of Position Feedback C ard of NC System with the ispLSI1016DeviceLin Lezhong Wang Yongqing Hu LiyunAbstract T he autho r desig ns and develops the position feedback card w ith the new insystem pro-gr ammable large scale integ ration device)paring with using the other g ener al IC de-vices,this card can improv e the logic and electr ic character i stics o f the whole position loop of N C system.T his design has a practical meaning for raising the pr ecisio n,reliability of the N C sytem.Key Words:ispLSI1016;counter;position feedback1引言位置板是实现闭环数控系统的关键硬件,其特性好坏直接影响整个数控系统的性能。

大型精密数控机床的运动部件行程较长,必须用位数多的位置板构成位置环,以实现位置闭环控制,这要求设计多位计数器。

用标准的IC芯片或一般的可编程逻辑器件PLD(如PAL、GAL等)可以完成这一设计,但是由于此类芯片的功能与管脚有限,而设计要求的逻辑较复杂,以致设计所用的芯片个数会过多,电路板的尺寸过大,同时电路的时延问题严重,时序难以保证,从而使设计难度增大。

---------------------元器件的分类：semiconductor, electronic components, integrated circuits (IC), passive components, active components, connectors, resistors, capacitors, diodes, transistors, switches, sockets一般分主动和被动元器件。

主动类的主要是指集成电路，就是我们说的IC或芯片；被动类的指接插件、电阻、电容、二极管、三极管、开关、插座等。

我们的业务多集中在主动类（体积小、价值大），兼做被动类（体积大、价值一般小，但也有很贵的）。

-------------------元器件厂家：brand, manufacturer全球有5000家以上行业认可的元器件生产厂家，生产的元器件有百万种之多，而且不断的推陈出新，用新产品来替代老产品。

元器件行业是现代工业的基础。

所有的电子产品都需要元器件来做成成品。

好比是建筑业，建筑公司就是我们现在说的OEM (original equipment manufacturer)。

他们采购不同的建筑材料（对我们就是元器件）来做房子（对我们就是电子产品和设备）。

众多的厂家生产的产品，其实独一无二的很少（哪怕是Intel生产的CPU，其他也有生产的，比如AMD、TI和Cyrix），某一厂家生产的大多数产品都有其他的厂家能生产，只不过在具体的性能指标上有这样那样的不同，很多是可以互相替换的。
