06 - Introducing PSpice Simulink Co-Simulation

PSpice Simulink Co-Simulation interface is an interface tool that links PSpice to the MATLAB® Simulink® system simulator, provided by The Mathworks.

PSpice is a SPICE-based simulator used for simulating electrical and electronic circuits, and The Mathworks tools are used for system designing. PSpice Simulink Co-Simulation interface integrates these two simulators to provide a simulation flow that can be used to design any kind of system with electronic subsystems.

Requirements for PSpice Simulink Co-Simulation Interface

You should have the following combination of The Mathworks and Cadence OrCAD and Allegro products installed on your system:

1. The Mathworks products
   • MATLAB R2019b or onwards
   • Simulink
2. Cadence OrCAD products or Cadence Allegro products
   Install one of the following design entry tools:
   • Capture or Capture CIS
   • Design Entry HDL
   Install the following simulator:
   • PSpice A/D
3. To be able to use the PSpice - MATLAB Interface, ensure that you have license for one of these products in your license file.
   • PSpice Designer Plus
   • OrCAD X Professional Plus
   • Allegro X PSpice System Designer

Setting Up the PSpice Simulink Co-simulation Solution

You can use one of the following two ways to setup the PSpice Simulink Co-simulation solution:

• Automatic Setup
• Manual Setup

Automatic Setup

To ensure that the MATLAB path settings are done automatically, do the following in PSpice:

1. Ensure that you have set the MATLAB path in PSpice. For details see, Setting Up the MATLAB Path.
2. Select Tools – MATLAB – Co-simulation to open MATLAB.

Manual Setup

When you want to launch MATLAB directly from the Start menu, instead of launching it from PSpice (Tools – MATLAB – Co-simulation), you need to set the PSpice Simulink Co-simulation solution path manually. To do so:

1. Set the PATH variable of your system as: <installation_directory>\tools\bin
2. Set the PSpice Simulink Co-simulation path in the PSpice installation in MATLAB. To do so:
   1. Launch MATLAB.
   2. Under Home tab, select Set Path.
   3. Click the Add Folder button and browse to the following location: <installation_directory>\tools\pspice\pspCosim
