OrCAD EE PSpice
OrCAD EE PSpice is a SPICE circuit simulator application for simulation and verification of analog and mixed-signal circuits. PSpice is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.
OrCAD EE typically runs simulations for circuits defined in OrCAD Capture, and can optionally integrate with MATLAB/Simulink, using the Simulink to PSpice Interface (SLPS). OrCAD Capture and PSpice Designer together provide a complete circuit simuation and verification solution with schematic entry, native analog, mixed signal, and analysis engines.
PSpice was a modified version of the academically developed SPICE, and was commercialized by MicroSim in 1984. MicroSim was purchased by OrCAD a decade later in 1998.
OrCAD PSpice Designer is available in two options- PSpice Designer and PSpice Designer Plus.
OrCAD PSpice Designer includes OrCAD Capture and OrCAD PSpice solution. An upgrade option to PSpice Designer Plus provides the PSpice Advanced Analysis simulation engine for functional simulation and improvement in design yield and reliability.
The PSpice Advanced Analysis simulation capabilities covers various analyses- Sensitivity, Monte Carlo, Smoke (Stress), Optimizer, and Parametric Plotter providing in depth understanding of circuit performance beyond basic validation.
The OrCAD PSpice Simulink- PSpice Integration(SLPS) provides co-simulation and helps verify system level behavior.
A circuit to be analyzed using PSpice is described by a circuit description file, which is processed by PSpice and executed as a simulation. PSpice creates an output file to store the simulation results, and such results are also graphically displayed within the OrCAD EE interface.
OrCAD EE is an upgraded version of the PSpice simulator, and includes automatic circuit optimization and support for waveform recording, viewing, analysis, curve-fitting, and post-processing. OrCAD EE contains an extensive library of models for physical components, including around 33,000 analog and mixed-signal devices and mathematical functions. OrCAD EE also includes a model editor, support for parameterized models, auto-convergence and checkpoint restart, several internal solvers and a magnetic part editor.
