OrCAD Capture and PSpice Designer together provide a complete circuit simulation and verification solution with schematic entry, native analog, mixed-signal, and analysis engines. OrCAD EE typically runs simulations for circuits defined in OrCAD Capture, and can optionally integrate with the MATLAB/Simulink, using the Simulink to PSpice Interface (SLPS). PSpice is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.

OrCAD EE PSpice is a SPICE circuit simulator application for simulation and verification of analog and mixed-signal circuits. It can be used to simulate, analyze renewable energy resources, transmission lines, electrical transients, standby switching of power supply. Though Simulink is general-purpose software for implementing graphical simulation, it has a specialized toolbox for simulating Power Systems. Then analyze and visualize the data in MATLAB. Run thousands of simulations in parallel. Use MATLAB to create input data sets to drive simulation. Directly using the thousands of algorithms that are already in MATLAB. When you use MATLAB ® and Simulink ® together, you combine textual and graphical programming to design your system in a simulation environment. Many electrical engineers find Simulink much easier to use than MATLAB. It is powered by Matlab programming language. Simulink is the GUI based companion software for Matlab. Simulink (GUI based software for Dynamic System Simulation) Matlab is a high-level programming language, it contains a good number of built-in functions to efficiently deal with matrices, numerical computations, symbolic mathematics etc. The programing language used in MATLAB (The software package) is also called Matlab. Toolboxes provide built-in functions to perform numerical computations including but not limited to Ordinary & Partial Differential Equations, Optimization, Linear System Implementation, Linear Algebra, Control System Design, System Identification, Curve Fitting. It contains add-on packages (called Toolboxes) for various functionalities. It has evolved over time and has become the most comprehensive software for Numerical Computing, Dyanimc System Simulations, Algebraic Solutions, Symbolic Mathematics etc. and was one of the first commercial packages for linear algebra. It was launched in 1983 by Mathworks Inc. MATLAB (MATrix LABarotary) is the most popular electrical engineering software among Electrical Engineering students. MATLAB (Software for Numerical Computing)
