请教 orcad-expedition interface的使用

都是根据它的帮助文档来操作的

先在orcad画好电路图test.opj，然后用mentorKYN.exe导出网表test.net;启动orcad-expedition interface，选择test.opj，选择层模板目录；

在expeditionPCB job manager wizard 中新建一个PCB工程，选择test.prj，操作完之后，打开test.pcb，提示back annotation has been disabled..............................Run forward annotation to create the logic database.但是运行ECO->forward annotation,提示信息为there are errors,see the log files, forwardannotation.txt。打开forwardannotation.txt为：

Forward Annotation ------------------

06:32 PM Monday, November 22, 2004 Job Name: D:\Expedition\3\3\PCB\3.pcb

Version: 01.01.00

The PDBs listed in the project file will be searched to satisfy the parts requirements of the CDB and to replace any duplicates found in the Target PDB.

The schematic source is a Keyin Netlist.

8: no valid page assigned previous to %%part/value - assuming page 1 10: no valid priority assigned previous to %%net - assuming priority 6 Netlist has no syntax errors

The Keyin Netlist has been read

Target PDB Name: Work\Layout_Temp\PartsDB.pdb

Number of Part Numbers: 1 Part Numb: 1k -> Vend Part:

Number of Part Names: 0

Number of Part Labels: 0

ERROR: A part was not found that had Part Number "1k". This is an error when the schematic source is a keyin netlist.

2 nets were found containing 0 pins 0 components were found

1 Parts DataBase, 0 Pin, and 0 CAE errors need to be corrected

DataBase Load is being terminated with 1 errors and 0 warnings. Logic Data has NOT been Compiled.

注：电路图中只有两个并联的电阻，封装设定为0805，

我用SDD2004－>library manager－>Library Manager for DC-DV-Expedition建的中心库，Partition下面有SM等几个分区，0805封装在SM下面。
