接 mentor en 设计流程中遇到的问题，急！

librarian 启动后出现了以下信息，第一个打“*”的默认的路经能改吗?
如果能，怎样改?
改到什么目录下比较好?

第二个“*”的警告如何消除?
第三个“*”如何设置?
* Warning: Default Data Prep search directory set to F:/MentorGraphics/MGC_HOME-2004.ixn/user/pcb_parts (from:   Idea/Librarian/Data Prep2 51)

第一个我改了环境变量，已经好了！

但是第二个和第三个还是不行！

* Warning: Directory F:/MentorGraphics/MGC_HOME-2004.ixn/user/pcb_parts/pcb_maps does not exist (from: Idea/Librarian/General   9E)
* Warning: Testpoint side must be specified during setup. (from: Idea/Util/Testpoints 0F)

有人知道DFI是什么意思吗?

这些WARNING是不要紧的，随他去好了

thank you！
