Application Note
Virtual Prototyping in PSpice Page 2 of 80
1 Overview
Virtual prototyping is a method in the process of product development, which allows to
validate a design before making a physical prototype. Since V17.2, PSpice offers the
opportunity to simulate System Designs using different kind of abstractions thanks to the
Device Modeling Interface. With GUI, users can define C/C++, SystemC, and Verilog-A
components and simulate them in simulator.
1.1 Contents of this document
• How to use Device Modeling Interface.
• Setup for Visual Studio Community 2013.
• How to integrate C/C++, SystemC and Verilog-A models to be simulated in PSpice.

• Hardware in the Loop using Arduino.
1.2 How to use this AN?
This document explains the steps for integrating C/C++, SystemC and Verilog-A models with
PSpice Device Model Interface (DMI), so that they can be used for PSpice simulations.
This document is valid up Release 17.2. License required for:
