Question

在allegro导入网表时出现如下错误，是什么问题呀？之前在orcad原理图生成网表时已经OK了。

Answer 1

#1 ERROR(1) Syntax error : unexpected character
PIN_NUMBER Syntax error : Expected '..' range specifier in line 321
File name : 'F:/myproject/allegro/pstchip.dat'

PIN_NUMBER有非法字符，打开这个文件 'F:/myproject/allegro/pstchip.dat'，找到321行，看看是那个器件的PIN_NUMBER有非法字符，然后在原理图里修改这个器件的原理图库，再导一次网表，如还有其它错误，再看提示，一个个排查。

Answer 2

这个是pin-number语法错误，因为里面有'..'，你可以查看下最新画好的元件里，哪有元件的管脚编号里有'..'出现。
