原创看图快速学PADS Router
PADS学习
PADS学习学会orCAD和PADS Layout软件的基本使用步骤，orCAD(找元件，定参数，添加库，生成链接文件，放大缩小、删除等基本操作等等)，PADS Layout( 导入链接文件、设置各种规则，布局、布线、检查等等)利用上面学到的完整的画一个简单的电路图。
先把整个流程过一遍。
pads logic,是设计电子电路图，原理图的工具，PADS LAYOUT 是设计PCB，PCB布局，布局，到GERBER FILE，PADS ROUTER是自动布线工具，附助PCB LAYOUT布线的工具。
建议用ORCAD画原理图，PADS LAYOUT 进行PCB 布局，布线当你将一个元件叠放在另一个元件上时，出现元件后退现象，说明两个元件在同一层，是报警的意思！要改变其中一个元件的层属性。
Ctrl+click 同时选择U1 和C1。
：Click是点击的意思。
1：为了移动原点，选择设置/设置原点(Setup/Set Origin)，在工作空间的某处按一下鼠标，这点将作为新的原点。
2:ctrl+enter:打开options3:循环选择(Cycle Pick)当你在一个工作区域按鼠标时，而目标处有多个目标切密度很高，选择一个目标也许要试许多次。
为了减少尝试选择的次数，你可以接受第一个选择，然后循环将哪个位置处所有的目标依此被选中。
1.将光标放在U1 的脚28 上，然后选择它。
2. 重复按键盘上的Tab 键，在管理脚28 处的各种可选目标将循环出现。
当你希望的目标出现后停止选择。
4:CAE封装(CAE Decal),在PADS 库中的一个逻辑符号，或称为CAE封装(CAE Decal).5：Ctrl+E:移动（先选中）Ctrl+I：用光标任意角度旋转(Spin)元件Ctrl+F，元件将返回到主元件面6：散开(Disperse)元器件(Component)：选择工具/散开元件(Tools/Disperse Components)7.打入SS U1，并且按回车(Enter)，使用搜索(Search)和选择(Select)直接命令，搜索(Search)并且选择元件U18：输入ss U* 在选中、在按ctrl+E、输入s 100 100。

PADS使用技巧
PADS软件是MentorGraphics公司的电路原理图和PCB设计工具软件。
目前该软件是国内从事电路设计的工程师和技术人员主要使用的电路设计软件之一，是PCB设计高端用户最常用的工具软件。
按时间先后：powerpcb----PADS2005----PADS2007----PADS9.0----PADS9.1----PADS9.2----PADS9.3——PADS9.4……，没有PADS2009。
2012-10-18发布PADS9.5Mentor Graphics公司的PADS Layout/Router环境作为业界主流的PCB设计平台，以其强大的交互式布局布线功能和易学易用等特点，在通信、半导体、消费电子、医疗电子等当前最活跃的工业领域得到了广泛的应用。
PADS Layout/ Router支持完整的PCB设计流程，涵盖了从原理图网表导入，规则驱动下的交互式布局布线，DRC/DFT/DFM校验与分析，直到最后的生产文件（Gerber）、装配文件及物料清单（BOM）输出等全方位的功能需求，确保PCB 工程师高效率地完成设计任务。
PADS2005sp2：稳定性比较好，但是很多新功能都没有；PADS2007：相比05增加了一些功能，比如能够在PCB中显示器件的管脚号，操作习惯也发生了一些变化；PADS9.2：相比以前的版本增加了一些比较重要的功能，比如能在PCB中显示Pad、Trace 和Via的网络名，能够在Layout和Router之间快速切换等等，非常好用。
还有，最重要的一点是：支持win7系统。
目前大多工程师使用的是PADS2007，同时Pads实现了从高版本向低版本的兼容，例如为了解决PADS2005能打开PADS2007的工程文件：PADS9.5加入了简体中文，虚拟管脚，底层视图（翻板）等功能可以在pads2007中保存为低版本的第一步:打开pads2007绘好的原理图档案，然后单击file/EXPORT选择要保存目标点击保存，再出现AscII OUTPUT 对话里点击select all,在output formats选择pads logic 2005 击ok第二步;开启pads logic 2005 点击file/inport选择打开刚刚导出文件就ok。
原创看图快速学PADS Router高级应用之一(宏的使用)
1.利用宏功能实现增加过孔与换层功能。
到此我们学完一个添加VIA宏动作过程，接下来，我们要为这个动作指定个快捷键，方便使用。
按下图数字标示，调出宏文件设置界面在Customize选项中点Keyboard and Mouse,找到Macros后双击。
到此就讲完了宏的录制，使用，和指定快捷键内容，大家回来到Router中，试一下按下X键是不是可以放过孔了，自已多试下，通过上面教程可以举一反三，比如说用一个键换层，（因PADS Router软件中没有直接换层功能，可以用此方法实现），方法类拟，大家自已去摸索，这里就不再重复讲述。
之前写了好几个教程，看图快速学PADS LAYOUT拼板，与快速学PADS Router放在百度文库上，取的不错反响，和下载量，但没几天发现我教程大量出现在其它网站，他们把别辛苦写出的教程自已轻松用CTRL+C, CTRL+V上传其它网站，疯狂地为自已谋利或刷分，看到这我心里不是滋味，体验了中国式盗版速度。
这也影响了我继续写原创作品的积极性，自从写了PADS拼板教程后，打算写一个PADS Layout高级应用全集，太长，写写停停，目前高级应用第一段，ECO 对比（PCB to PCB,ORCAD原理图to pcb双向对比变更，CAM输出模板的创建与调用，手工贴片图输出，PCB中的重复模块的创建与调用）相关教程已快写好，整理后一部分一部分放出，写好一个好的教程工作量很大，平时没时间，都是在业余时间想到一点写一点，写的全是我多年应用经验，内容尽量写得通俗易懂，实例与讲解结合，尽量多写一点书上找不到的，又比较实用的功能。
后续还会推出PADS Layout高级应用之二及其它相关教程如：高速PCB设计要点，EMC，EMI设计实战，及电源安规/EMC在PCB设计时注意事项等，敬请期待。
此原创作品限PCB技术交流，请支持原创，下载后只可供自已学习用，请不要上传到其它网站，为自已谋利刷分等，请支持原创，拒绝盗版。

添加蛇形走线
添加蛇形走线通常在交互式走线过程中才会用到，在交互式走线过程中鼠标右键选择Add Accordion 。
使用Add Accordion 命令，那么在走线过程中，你每点击一次鼠标左键就添
加一个蛇形线段。
还可以通过鼠标在设计中的光标的位置选择来定义蛇形走线以及幅度值。

成蛇形走线定义后双击鼠标左键回到交互式走线状态。
上图中的红色箭头表示蛇形走线被确定的位置。
定义蛇行走线的起始位置
当你开始添加蛇行走线，你有几种方法去定义走线参数。
当你使用默认参数
的时候，只要你确定了走线的起始位置，那么随着光标的移动讲自动添加蛇行走线。
你只需在起始位置点击一下鼠标左键。
设置蛇行走线
1、选择CLKIN 这个网络，点击鼠标右键选择Unroute 撤消当前的走线。
2、在未选择任何对象状态下鼠标右键选择Select Trace/Pins/Unroutes。
3、在标准工具栏中的层目录中选择Primary Component Side 为当前操作层。
4、右键Interactive Route 或F3 开始对该网络走线。
提示：在增加蛇行走线的时
候按Ctrl+L 快捷键查看走线长度。
5、走线过程中在板框开放区域增加一个新的拐角作为蛇行走线的起始点。
6、鼠标右键选择Add Accordion
7、在你所需走线方向移动光标，PADS Router 开始按照默认参数来进行蛇行走线。
8、增加你所需要的蛇行走线后双击鼠标左键或鼠标右键选择Complete Accordion 回到交互式走线状态。
9、继续完成走线。
自定义蛇行走线
可以通过鼠标选择点来定义蛇行走线参数第一次左键选择走线起始点，
第二次确定蛇行线的振幅位置，即可以在走线的过程中改变振幅大小以及蛇行走线的方向。
提示：此时设置的蛇行走线并不影响原先的默认参数。
