第一个(想在原始BRD上修改):打开dsn,创建网表的时候,在“input borad”中输入原来的BRD文件,在“output board”中输入新的BRD文件名,可以成功。
第二个(想完全新建一个BRD):打开dsn,创建网表的时候,在“input borad”中不输入任何文件(保留为空白),在“output board”中输入新的BRD文件名,但是失败了!提示:ERROR: netrev failed !session log 中显示如下:(部分摘录)

注意:其中“D:\MP4_DSP\焊盘封装\”这个路径是我从原来的BRD文件中导出来的所有文件,没有做任何修改和删除!
请问第二个方法(想完全新建一个BRD)的过程中上面出现的错误是什么原因?怎么解决???
