OrCAD PSpice

Easily verify circuit behavior and optimize your designs with industry-leading, SPICE simulation.

Achieve Peak Circuit Performance

Easily simulate, analyze, and optimize your circuit functionality with the world’s most reliable SPICE simulator. PSpice delivers a complete circuit simulation and verification solution with native analog/mixed-signal analysis.


Integrated Simulation

Analyze critical circuits with native analog and mixed-signal simulation engines directly from the schematic. Seamless integration with the schematic provides easy-to-understand results with color-coded graphical waveforms and probes as well as bias point information overlays.


Extensive Model Support

Quickly define and simulate circuits with over 33,000 simulation-ready models from various IC vendors as well as pre-defined, configurable models for sources, switches, transformers, capacitors, inductors, and more. Enable rapid creation of simulation-ready models for common components and magnetic parts with datasheet-driven modeling wizards. Integrated C/C++ and SPICE simulation engines enable you to fully model mixed signal electronic devices at any level of abstraction directly from the schematic.


Advanced Mixed-Signal Simulation and Design Optimization

Easily perform Time Domain (Transient), DC Sweep, AC Sweep, and Bias Point for comprehensive circuit analysis. Then seamlessly evaluate multiple design implementation options to improve yield, reduce design costs, increase circuit reliability, and fine-tune circuit behavior with the advanced analysis features in PSpice.


Waveform Analysis and Reporting

Delve into simulation results using best-in-class waveform viewing and analysis capabilities with automatic computation of measurements using built-in analog and mathematical functions. For comprehensive analysis, quickly transform results to analyze Bode Plots, Fourier Transforms, derivatives, and more.
