这种错误

Answer 1

#1 ERROR(24) File not found
Packager files not found 一个错误是没找到指定网表。你网表的路径指定在你原理图输出的一个文件夹***/allegro的文件夹，而且网表确定已经输出。

追问

最开始是这样导网表的

用PCB Editor就会有好多错

追答

网表有错误就要解决，否则网表没有生产，PCB找不到网表。里面你导不进去。你可以看看你网表里都是是吗错误，错误有很多类的哦。

Answer 2

Duplicate Pin Name "NC" found on Package LFE3-150E-FN1156CES_1-1 ,

问题是你原理图封装管脚定义上有重复冲突，AG28 AG29，最好将它们定义成NC0，NC1这样子，修改后应该就没有问题。

追问

改过后依然是这样的错误Duplicate Pin Name "NC" found on Package LFE3-150E-FN1156CES-1 , U1-1 Pin Number AH3: SCHEMATIC1, P04_FPGA-LOGIC (9.80, 10.20). Please renumber one of these

追答

我按照类似的问题做了个实验，如附件的动太图片所展示，是可以解决的。

追问

谢谢你做个动态图帮我解答，可是我已经把名字改了，但依然报没改之前的错误

Answer 3

你有两个命名为NC的引脚，试着修改为NC1和NC2

追问

改过依然是同样的错误

追答

你外面的AH3等是pin number还是网络标号，如果是number完全可以用数字代替，不知道是不是引脚name和number冲突。如果是网络标号你命令选择对了吗？仔细查找下，问题不大，应该能解决

追问

但依然会出现下面的错误

Duplicate Pin Name "NC" found on Package LFE3-150E-FN1156CES_1-1 , U1-1 Pin Number AH1: SCHEMATIC1, P04_FPGA-LOGIC (18.65, 0.55). Please renumber one of these.
