Pads2007原件库制作流程
深圳市未来科技有限责任有限公司PADS2007系列教程(元件库制作步骤)启动PADS Logic如果你现在还没有启动PADS Logic程序，可以通过WindowsXP环境下启动，点击开始/程序/MentorGraphics SDD/PADS2007.2/Systen Design/PADS Logic使其运行，同事也可以通过桌面上的图标进行启动。
开始制作PADS Logic原件点击图标开始启动PADS Logic界面，会弹出一个开始界面鼠标双击Ship弹出选择对话框。
Skip表示跳过。
Manual表示手册、指南。
Auto表示自动。
一般此项根据个人爱好选择字体，然后再Mode选择栏选择Skip就回到系统默认的对话框。
然后再点击OK键，就进入了PADS Logic操作界面。
PADS Layout工具栏和工具盒PADS Logic 使用Windows 标准的工具条(Standard Toolbars)和工具盒(Toolboxes)设计(Design)工具盒，该工具盒包含工具条和选择(Selection)工具盒，该工具盒包含工具条这些图形代表了有效的命令，称为图标(Icons)。
工具条(Toolbars)位于菜单栏(Menu Bar)的上面。
无模命令(Modeless Commands)和快捷键(Shortcut Keys)无模命令 (Modeless Commands)和快捷键 (Shortcut Keys)允许您通过键盘直接输入命令及其选项。
例：标准的 Windows 快捷键，如Alt-F 用于显示文件菜单等命令，在 PADS Logic中同样有效。
关于具体的无模命令可打开帮助菜单(Help) 下的Modeless Commands 选项进行查看取消命令操作您可以在任何时候，通过按键盘上的 Esc 键或按鼠标右键并从弹出菜单(Pop-up Menu)中选择取消(Cancel)命令，取消当前的命令和命令序列使用工作空间PADS Logic 的工作空间为56 英寸x 56 英寸。

可以通过“Library”菜单选择需要的元件库，也可以使用“Search”功能查找特定元件。
3.连接元件使用“Place Wire”工具进行连接元件，单击鼠标左键从一个引脚拖动到另一个引脚即可连线。
可以使用“Change Line Width”工具更改连线的宽度。
4.设定电源和接地使用“Place Power Port”工具添加电源和接地，然后连接到元件的对应引脚。
可以在元件属性中调整电源和接地的设置。
5.设定信号线使用“Place Signal”工具添加信号线，可以在元件之间连接各种信号。
可以使用“Change Line Style”工具更改信号线的样式。
6.设定网络在PADSLOGIC中，网络是指一组连接在一起的元件和信号线，可以使用“Create Net”工具设定网络。
可以在属性选项中设置网络的名称和属性。
7.设定封装库在PADSLOGIC中，封装库是用来存储元件的封装信息的，可以使用“Place Library Reference”工具添加封装库。
可以在元件属性中选择需要的封装库。
8.保存工程在工程操作完成后，一定要及时保存工程，可以点击“File”菜单中的“Save”选项保存工程。
也可以使用“Save As”功能保存工程的副本。
pads2007教程 (2)
PADS 2007 教程简介PADS 2007是一种电子设计自动化（EDA）软件，用于进行PCB（Printed Circuit Board）设计和布局。
它是一款功能强大且易于使用的工具，可以帮助工程师们快速而精确地设计印刷电路板。
在这个教程中，我们将带您了解PADS 2007的基本知识，并进行一些实际的操作示范，帮助您快速上手和掌握该软件的使用方法。
环境设置在开始PADS 2007之前，确保您的电脑符合以下最低要求：•操作系统：Windows XP或更高版本•内存：至少2GB•硬盘空间：至少2GB•屏幕分辨率：1024x768或更高分辨率完成硬件要求后，您需要下载和安装PADS 2007软件。
请注意，PADS 2007是一款商业软件，需要购买许可证才能使用。
创建新工程在PADS 2007中，我们可以创建一个新的工程来进行PCB 设计和布局。
下面是创建新工程的步骤：1.启动PADS 2007软件，并选择“File” > “NewProject”。
2.输入工程名称和保存路径，并选择一个设计模板（如果有）。
3.点击“Next”并按照向导的指示完成创建工程的过程。
PCB布局设计一旦创建了新工程，我们就可以开始进行PCB布局设计。
以下是一些基本的布局设计步骤：1.绘制板卡轮廓：在PCB编辑器中，使用绘图工具绘制PCB的轮廓。
这将决定PCB的尺寸和外形。
2.定位组件：将所需的元件（IC、电阻、电容等）拖放到PCB编辑器中，根据需要进行定位和旋转。
3.连接器布局：根据电路原理图，将连接器放置到合适的位置上，确保与其他元件的连线正确连接。
4.连线布线：使用布线工具将组件之间的连线进行布线。
5.添加电源和地线：将电源和地线引导到适当的位置，确保电源供应的稳定性和地线的良好连接。
6.规划布局：对PCB进行规划，确保元件和连线之间有足够的间距，以避免干扰和短路。
信号完整性和电磁兼容性在设计PCB时，我们需要考虑信号完整性和电磁兼容性。
PADSlogic入门教程
设置PIN脚起始号、步进值 (默认序号从1开始递增， 步进为1),单击OK完成。
标好序号后再对 引脚进行命名
输入引脚名称，电阻电 容可直接名为1、2,MOS 管则可为G、D、S，具体 应参考元件规格书。
如果命名错误也可 以更改引脚名称。
点击Set Pin Type按 钮，设置PIN脚类型， 例如电源引脚、双向引 脚、未定义等等，我们 一般设置成未定义。
PADS Logic入门教程
—以PADS2007为例
点击菜单栏file，新 建一个原理图文件
一.手工编辑元件库
点击菜单栏Tools/Part Editor，进入元件库编
辑模式
点击工具栏中Edit Graphics按钮，创建元 件的CAE图形及类型。
注：一个PADS Logic元件由以下三个基本单元组成 *元件类型：元件名称、连接引脚、逻辑单元、门交换信息 *CAE图形符号：原理图中元件的几何形状 *PCB封装：PCB设计中元件的几何形状
元 件 名 称
传递成功后即可对元 件进行布局、布线
网 络 名 称
布线前先设置一些规则， 我们将在PADS Layout入
门中继续探讨学习
三.绘制原理图
编辑好所需元件进入原理图 编辑界面,点击设计工具栏中
Add Part按钮,添加元件.
先选择元件库, 再在元件库中 查找所需元件, 和Protel类似, 选中元件点击 Add按钮即可添 加到原理图中
依次放置所需元件,单击 右键完成一个元件的放置, 再点击Add添加其它元件.
放置好后对元件进 行布局调整并编号
注：AutoCAD格式的图形尺寸需 要先放大39.37倍才能导入到 PADSLayout中。
选择放大后的*.DXP文档，导 入到PADS Layout的结构图

你也可以学到如何从text文件导入die焊盘数据以及修改导入的数据。
本节将学习：输入die参数数据从ASCII文本文件导入die数据修改导入的die数据增加die到设计中了解ASCII文本文件格式在本节中我们将使用Start-up文件来设置所要求的参数。
打开 start up 文件菜单File > New使用 Start-up 文件:1. 在 Set Start-up File 对话框中，选择PBGAtutorial.stp。
提示：如果 Set Start-up File 对话框没有出现，在File菜单中选择Set Start-upFile进入选择。
或者将对话框中的Don’t display again选项勾去除，下次新建文件时将显示此对话框。
2. 点击OK按钮。
