How to export and use the package library in the PCB project in Cadence Allegro?

Export and use of package libraries in projects

Specification of package library path

In Setup-User Perference-Paths-Library, zhi'dzhid

pays special attention to three paths:

• devpath: Used for third-party netlists (netlists exported by other methods). Since only first-party netlists are usually used, this item can actually be ignored.
• padpath: the path where the pads of the PCB package are stored
• psmpath: the path where the content such as the Flash file used in the PCB package pad and the Shape file used in the PCB package pad are stored.

The dra file is a graphics file,
pad is a pad file,
ssm is a shape symbol,
and psm is a package symbol

Export all packages of a project

When calling the package library, if there are packages that need to be used in other projects, you can export the existing packages in the previous project for reuse.
Click File—Export—libraies

1. Check all (export device files, pads, etc.) 2. Specify the export location 3. Click Export

Separately export a certain package in the project

1. Open dra format file
2. File-Creat Symbol/Device can get psm and txt files
   
   3.Tools-Padstack-Modify Design Padstack...-Edit-File-Save to File to get pad files.
   
   
   
3. At this point, the psm, pad, and txt files are obtained, and these three files can be placed in the specified location of the previous packaging library path to call.

So it can be seen that as long as there are these three files, the call can be realized. If there are already these three format files in the folder, there is no need to create and call directly.
