Answer 1

#1 WARNING(SPMHNI-192): Device/Symbol check warning detected.

WARNING(SPMHNI-194): Symbol 'P_1X2' for device 'BOTT1_P_1X2_RTS' not found in PSMPATH or must be "dbdoctor"ed.

这种类型的错误，你要1.确认元件的封装名是否和库的封装名完全一样。2.确认下封装文件包括 .dra .psm .pad 这3个。

#4 WARNING(SPMHNI-192): Device/Symbol check warning detected.

ERROR(SPMHNI-196): Symbol 'SW_4' for device 'SW PUSHBUTTON_SW_4_SW PUSHBUTTO' has extra pin '3'.

ERROR(SPMHNI-196): Symbol 'SW_4' for device 'SW PUSHBUTTON_SW_4_SW PUSHBUTTO' has extra pin '4'.

这类错误是因为你的原理图中的器件管脚数和封装管脚数不一样。必须保证原理图中器件的管脚数对应封装的管脚数。比如你用一个按键，只用了2个引脚，原理图中也是两个引脚。但实际封装是四个引脚，那么你就要改你原理图中的按脚为四个引脚。

Answer 2

整了好几个小时才搞定：-----出现 WARNING(SPMHNI-194): Symbol 'P_1X2' for device 'BOTT1_P_1X2_RTS' not found in PSMPATH or must be "dbdoctor"ed.

--------1、先确认封装焊盘和封装元件（即pad,psm)的库已经放在了PCB的路径下；如果没有则设置一下：STEUP--->USER Preferences,在左方下拉菜单的paths----library,然后点右侧的padpath位置右键点击选择对应的PAD放置文件夹位置；psmpath右面点击元件封装的文件夹；

2.如果第1项还是未能导入，确认原理图封装名字和PCB封装的名字是否完全一样？

3、检查原理图的元件名或备注名是否有不合规字符，如空格，/等符号；

4.检查PCB的画图区域是否太小放不下未能导入的那个元件（有时无提示，需要自己检查，单位设置正确后，看区域是否太小。这是参考了以下链接的高手的提醒，记录一下。
