从原PCB中导出Libraries,生成*pad,*dra,*txt文件,修改*dra文件使之生成*psm文件,在原理图中填入同名的PCB footprint,导入网表至Allegro时提示如下错误,在Allegro里封装出不来
#1 ERROR(305) Device/Symbol check error detected.
Unable to load symbol 'CC0805' for device 'R_CC0805_R': Couldn't find padstack: PAD2
due to Unable to load Flash symbol PAD2.
PAD2是导出Libraries时生成的*pad文件,我已经将它们放入指定地址,不知是何原因,请问如何使用导出的Libraries封装?
