Configuring PSpice Schematics

Types of Libraries
Schematics recognizes two types of libraries:
Default Library Directory
Schematics includes a default library directory where all
the symbol libraries (.
slb) you selected during installation
reside. It is not required to configure these libraries. They
are already configured in the search list as global libraries.
However, if you prefer, you can:
• change the order in which libraries appear in the
search list, thereby changing the order in which they
are searched
• remove library names from the search list (without
deleting the libraries)
• add new libraries
• delete libraries
• reconfigure libraries from global to local
This library... Is available...
global to all schematic designs. They are listed
in the pspice.ini file and are
automatically loaded into the library
search list for every design.
Global libraries appear in the library
search list with an asterisk (*) preceding
the library name.
local to designs within which they are saved.
Schematics always places local library
names at the top of the library search
list. Local libraries are always searched
first.
Note To maintain t

f
your
default symbols, we recommend making a
copy of the default symbol libraries. If you
use the symbol editor to make changes to a
default symbol, it will overwrite the default
symbol if you save using the default file
name. Also, if you import symbol files into
the default library and an imported file has
the same name as the default file, the
imported file will overwrite the default file.
