Academic Library System
Notes (iii) In order to coordinate our work better in serving our users, an open communication
policy has been gradually instituted in our workplace since last year. Regular updates
and briefing sessions are held with staff members in a variety of formats, from large
group to individuals. A Library Team site will be developed to share information amongst
staff and to act as a repository of library administrative records, procedures and policies.
3.4 Steps and Components of Planning
Schematic component symbols are created in schematic libraries. The components in these
libraries then reference footprints and other models defined in separate footprint libraries and
model files. As a designer, you can place components from these discrete component libraries
or you can compile the symbol libraries, footprint libraries and model files into integrated
libraries. The advantages of integrated libraries are that they are portable (everything is in one
file) and the components and models in them cannot be edited. The bulk of Altium Designer
components (around 70,000 ISO compliant components) are supplied in integrated libraries,
which you will find in the Library folder of your Altium Designer installation. You can extract
the source libraries out of an integrated library, to do this open the integrated library and
choose Extract Sources to extract the source libraries, which will then be opened for editing.
For more information, refer to the Building an Integrated Library tutorial.
Creating Schematic Components
The Schematic Library Editor is used to create and modify schematic components, and manage
component libraries. It is similar to the Schematic Editor and shares the same graphical design
objects, with the addition of the Pin tool. Components are created with the design objects in
the Schematic Library Editor. Components can be copied and pasted from one schematic
library to another or from the schematic editor to the schematic library editor.
Creating a New Library Package and Schematic Library
Before we start creating components, we need a new schematic library to store them in. This
library could be created as a stand-alone library, referencing models in separate files. An
alternate approach is to create the new schematic library with the intention of compiling it and
the referenced models into an integrated library package. This means that before we create the
library we need to create a new library package. A library package is the basis of an integrated
library – it binds together the separate schematic libraries, footprint libraries and model files
that are ultimately compiled into the single integrated library file.
