Protel 99学习笔记

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:protel 99se 封装时出现footprint not found in library

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。
