（1）Warning "No_connect"

#1 Warning [ALG0047] "No_connect" property on Pin "P1.8"

ignored forP1: SCHEMATIC1, 13)URAT (7.90, 1.20). Connecting

pin to net "N16811229".&H)K]-hwM

ALG0047，这个警告基本可以忽略；造成这个问题的原因是，设计之

初先对器件相关的管脚上加上'X'(也就是NC符号)，更新设计的过

程又对管脚做了连接处理；但是后面的连接处理没有去掉管脚的NC

属性，不信的话把那个管脚上的net删掉看看。 RG9f

解决办法很简单，对这些管脚再做一次NC

（2）Warning Part Name

#5 Warning [ALG0016] Part Name "CAP PN_C100UP-6.3V-SMT-

S_100UF/6.3V" is renamed to "CAP PN_C100UP-6.3V-SMT-

S_100UF/"

这个警告不可避免，allegro对相关的属性名称进行合并，超过一

定数量的字符就截掉；在命名规范的前提下就不考虑这个警告了。

无法根治

这个#2 Warning [ALG0016] Part Name "?j#w?rm

之类的错误在于你建立元件原理图的时候你的原件Value值太长了

超过32个字符,从而使系统在进行命名规范的时候溢出,而出错,很

简单的,只写关键元件名,比如 A2541P10_HDR2X5-100MIL_2X5

HEADER" is renamed to "A2541P10_HDR2X5-100MIL_2X5 HEAD错误

只需要

把2X5 HEADER更改为A2541P10,去除中间的空格即可.

Allegro对一些字符[例如"空格","小数点"等等]很在意,可以参阅

相关文档的描述.
