Chapter 4 Creating and editing models

Changing model library search order
Two reasons why you might want to change the search
order are to:
• reduce the search time
• avoid using the wrong model when there are model
names duplicated across libraries; PSpice always uses
the first instance
To change the order of libraries
1 On the Libraries tab of the Simulation Settings dialog
box:
a Select the library name you wish to move.
b Use either the Up Arrow or Down Arrow toolbar
button to move the library name to a different
place in the list.
2 If you have listed multiple *.LIB commands within a
single library (like NOM.LIB), then edit the library
using a text editor to change the order.
Example: The model libraries DIODES.LIB and
EDIODES.LIB (European manufactured diodes) shipped
with your OrCAD programs have identically named
device definitions. If your design uses a device out of one
of these libraries, you need to position the model library
containing the definition of choice earlier in the list. If
your system is configured as originally shipped, this
means you need to add the specific library to the list before
NOM.LIB.
See Handling duplicate model
names on page 4-122
for more
information.
Caution—Do not e
d
it NOM.LIB. I
f
you
do, PSpice will recreate the indexes for
every model library referenced in
NOM.LIB. This can take some time.
