Basic controlled sources
As with basic SPICE, PSpice has basic controlled sources
derived from the standard SPICE E, F, G, and H devices.
Table 1
summarizes the linear controlled source types
provided in the standard part library.
Creating custom ABM parts
Create a custom part when you need a controlled source
that is not provided in the special purpose set or that is
more elaborate than you can build with the general
purpose parts (with multiple controlling inputs, for
example).
The transfer function can be built into the part two
different ways:
•
directly in the PSPICETEMPLATE definition.
•
by defining the part’s EXPR and related properties (if
any).
The PSpice syntax for declaring E and G devices can help
you form a PSPICETEMPLATE definition.
