1导入网络表出现错误: Add node D1-2 to net GND Error: Node Not found

同2

2:二极管封装与原理图中的元件,管脚标号不一致,封装管脚标号改成A和K

解决办法:把三个引脚的属性改成了passive

6:[b]protel 99se 封装时出现footprint not found in library[/b]

元件的封装没有找到

其他的些错误及解决方法

floating input pins on net DDR-A0:连接线的时候没有连接到元件的端点。

unconnected net label on net DDR-D0

把label没有放置正确,放的时候出现一个圆点的时候才算放好

output pins and power pins on net net U32-M2

输出端子和电源接在一起

unconnected input pins on net B.EM-A10线没有连接好,放置导线的时候。

Multiple output pins on net U14-2 我也在研究

Action;Add node DC2-39 to net ATA.IORDY Error:node not found:元件的引脚名和封装引脚的引脚名不一致,比如二极管元件引脚是A和K,封装是1和2.

component not found:元件设置的封装名和PCB的通用封装名不一致;比如元件封装设置为DIP-14,而通用封装是DIP14。


追问:

PCD通用封装名是什么,在哪里看啊,怎么设置?

我用的CON3出现的问题,就改了个text应该不会影响吧。还有part里面的footprint是什么意思。

出现的错误

Macro 1: New Component

Add new component A7

Error: Footprint not found in library

Macro 2: New Node

Add node A7-1 to net NetA7_1

Error: Component not found

Macro 3: New Node

Add node A7-2 to net SGND

Error: Component not found

Macro 4: New Node

Add node A7-3 to net NetA7_3

Error: Component not found

7: Net XTAL1 is broken into 2 sub-nets. Routed To 50.00% PCB检查规则

就是你有一根飞线还没有连,仔细看下,你可以看出来,我也是遇到同样的情况。

你可以把文档的栅格线改成星点线,这样容易看出来是哪里的飞线没有连。
