cadence具有导入导出器件位置placement的功能txt纯文本文件AOM项目中可高效率实现与原版相同的器件布局
主要的耗时工作是两PCB之间器件位号的映射关系
# 导出:
1. 从dxp中设置坐标Edit-Origin-Set可选择某一元件作为坐标原点
1. 然后导出器件位置File-Assembly Outputs-Generates pick and place file配置导出的项并拖拽排序
![dxp坐标文件配置示例.png](../../../_resources/dxp坐标文件配置示例.png)
# 映射:
dxp的导出格式和cadence的导入格式有细微差别列项所在的位置器件所在层、旋转角度的表示方法
cadence的Placement文件格式示例

可用excel轻松转换映射过程中还要注意封装的匹配
# 导入:
cadence中File-Import-Placement由于封装的不同建议Placement Origin选择Body Center
