PSpice User Guide Analog behavioral modeling October 2019 322 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Overview of analog behavioral modeling You can use the Analog Behavioral Modeling (ABM) feature of PSpice to make flexible descriptions of electronic components in terms of a transfer function or lookup table. In other words, a mathematical relationship is used to model a circuit segment, so you do not need to design the segment component by component. The part library contains several ABM parts that are classified as either control system parts or as PSpice-equivalent parts. See Basic controlled sources on page 373 for an introduction to these parts, how to use them, and the difference between parts with general-purpose application and parts with special-purpose application. Control system parts are defined with the reference voltage preset to ground so that each controlling input and output are represented by a single pin in the part. These are described in Control system parts on page 327. PSpice-equivalent parts reflect the structure of the PSpice E and G device types, which respond to a differential input and have double-ended output. These are described in PSpice-equivalent parts on page 354. You can also use the Device Equations Developer's Kit for modeling of this type, but we recommend using the ABM feature wherever possible. With the Device Equations Developer's Kit, the PSpice source code is actually modified. While this is more flexible and produces faster results, it is also much more difficult to use and to troubleshoot. Also, any changes you make using the Device Equations Developer's Kit must be made to all new PSpice updates you install. Note: The Device Equations Developer's Kit is available to qualified customers only. Please contact PSpice Customer Support for qualification criteria. Device models made with ABM can be used for most cases, are much easier to create, and are compatible with PSpice updates.
