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.（3）Error Illegal character "Dot(.)" found in "PCB Footprint"#1 Error [ALG0081] Illegal character "Dot(.)" found in "PCB Footprint" property for component instance C255:PG16_AC97, PG16_AC97 (226.06, 132.08) .封装命名不能包含“.”（4）Error Illegal character "Forward Slash(/)" found in "PCB Footprint" property#1 Error [ALG0081] Illegal character "Forward Slash(/)" found in "PCB Footprint" property for component instanceC255: PG16_AC97, PG16_AC97 (226.06, 132.08) .#2 Error [ALG0081] Illegal character "Forward Slash(/)" found in "PCB Footprint" property for component instance D3: PG01_LED&Switch&7-Segment Disp, PG01_LED&Switch&7-Segment Disp (93.98, 33.02) .#3 Error [ALG0081] Illegal character "Forward Slash(/)" found in "PCB Footprint" property for component instanceC245: PG16_AC97, PG16_AC97 (205.74, 35.56) .封装命名不能包含“/”（5）比较隐藏的排除法Loading...
