voltage output is required, use an E part type. If a current output
is necessary, use a G part type.
Each E or G part type in the
abm.slb symbol file is defined by
a template that provides the specifics of the transfer function.
Other attributes in the model definition can be edited to
customize the transfer function. By default, the template cannot
be modified directly using Attributes on the Edit menu in
Schematics. Rather, the values for other attributes (such as the
expressions used in the template) are usually edited, then these
values are substituted into the template. However, the symbol
editor can be used to modify the template or designate the
template as modifiable from within Schematics. This way,
custom symbols can be created for special-purpose application.
Implementation of PSpice A/D-
Equivalent Parts
Although you generally use Schematics to place and specify
PSpice A/D-equivalent ABM parts, it is useful to know the
PSpice A/D command syntax for “E” and “G” devices. This is
especially true when creating custom ABM symbols since
symbol templates must adhere to PSpice A/D syntax.
The general forms for PSpice A/D “E” and “G” extensions are:
E <
name>
<
connecting nodes
> <
ABM keyword>
<
ABM function>
G <
name>
<
connecting nodes
> <
ABM keyword>
<
ABM function>
where
<name> is the device name appended to the E or
G device type character
<connecting
nodes>
specifies the <(+ node name, - node
name)> pair between which the device is
connected
