Allegro PCB 转 PADS Layout

操作系统：Windows 10 x64

工具1：Allegro PCB Design XL (legacy) version 16.6-2015

工具2：PADS Layout VX.2.3

参考3：http://www.eda365.com/thread-106414-2-1.html（异常解决方法）

参考4：Allegro转PADS以及后续修改

参考5：Allegro to PADS Layout Translator User's Guide（用户手册）提取码：x8fs

由PADS提供的参考手册，只要安装了PADS，就可以在X:\MentorGraphics\PADSVX.2.3\docs\pdfdocs里面找到该文件，文档原名《allegro2pads.pdf》。

情况1：Cadence、PADS安装在同一台机器上。

步骤1：

复制：<PADS安装目录>\SDD_HOME\translator\skill_scripts中的内容，以及<PADS安装目录>\SDD_HOME\translator\win32\bin\tech_translator.exe

Allegro PCB 转 PADS Layout

到D:\Cadence\SPB_Data\pcbenv

注意：Cadence一般是安装在C盘的，而我是将Cadence安装在D盘。

Allegro PCB 转 PADS Layout

步骤2：

确保以下列出的三个环境变量已设置正确。

变量：SDD_HOME，值：D:\MentorGraphics\PADSVX.2.3\SDD_HOME（值取决于PADS的安装路径）

变量：AEX_BIN_ROOT，值：D:\Cadence\SPB_Data\pcbenv（值取决于Cadence的安装路径）

变量：AEX_ENABLE_JOBPREFS_LAYER_FIX，值：1

步骤3：

创建一个新文件夹，将需要转换的.brd设计文件复制到这里面，使用Allegro PCB Design XL (legacy) 打开该设计文件。

在command提示窗口中输入下列命令：skill load "dfl_main.il"，并按回车键。dfl_main.il文件来自<PADS安装目录>\SDD_HOME\translator\skill_scripts。

注意：第一次输入可能没有反应，你需要再次输入。反正我的就是这样，第一次输入之后，按回车键，只显示一个“t”。

Command > skill load "dfl_main.il"

根据Allegro to PADS Layout Translator User's Guide（提取码：x8fs）给出的信息，执行脚本之后，如果有错误，是必须解决的，否则无法正确地生成输出文件。上面列出的信息，只有警告，我也不知道是否会产生什么特别严重的问题。

执行命令skill load "dfl_main.il"之后，还需要在Command提示窗口中输入另一命令main out，这会打开Allegro To Xpeditio...对话框，点击Start Translation启动转换，转换期间会弹出许多窗口，这个不用管。

注意：.brd设计文件的文件名不能带有空格或其它特殊字符，存放设计文件的文件夹也类似。我一开始转换的时候，就是因为文件名、文件夹名中带有空格，导致错误而折腾了很久。
