     The PDBs listed in the project file will be searched to satisfy the parts
      requirements of the CDB only for parts not already found in the

     The schematic source is a DxDesigner Generic Data Base.

     The AllowAlphaRefDes status indicates that reference
      designators containing all alpha characters should be deleted
      and the relevant symbols repackaged.

     DxDesigner Data Base has been read

注意看这句：“ERROR:  Unable to open Source Parts Data Base F:\MentorGraphics\PartsDBLibs\CON.pdb for reading.”

检查一下你的画原理图时指定的中心库是F:\MentorGraphics目录下的吗?有F:\MentorGraphics\PartsDBLibs\CON.pdb这个文件吗?
