• MacSpice is a simple yet powerful macOS application that is able to analyze and simulate the activity of an electric circuit, regardless of its complexity. The utility is based on the Berkeley Spice 3f5 simulator. The simulator is able to handle circuits that include resistors, different types of sources or switches, semiconductor devices.
• EasyEDA EasyEDA is a free circuit simulator on Mac for electronic circuit design.
• Powerful Simulation. Analyze, and optimize critical circuits and components using powerful OrCAD PSpice technologies with native analog, mixed-signal, and analysis engines. Circuit Optimization. Maximize circuit performance, yield, and reliability with temperature and stress analysis, worst-case analysis, Monte Carlo analysis, and performance.

MacSpice is a simple yet powerful macOS application that is able to analyze and simulate the activity of an electric circuit, regardless of its complexity. The utility is based on the Berkeley Spice 3f5 simulator.

The simulator is able to handle circuits that include resistors, different types of sources or switches, semiconductor devices, inductors, transmission lines, and so on. To help you get stated, the developers also provide a collection of example circuits that you can analyze on your own.

Powerful electric circuit simulator featuring a console like user interface

PSpice technology has been supporting the student community for years, helping them achieve academic and career success. To help students with the learning process, we offer a free version of PSpice via the OrCAD Academic Program. The academic version is a complete suite that includes the Capture and PSpice tools to assist students in lab.

The MacSpice main window is represented by a console like window that allows you to manually input various commands. When you open the utility for the first time, you will be able to see a list of useful commands: you can load new circuit files, execute analysis, edit the source, or draw the results for different variables values.

Within the MacSpice console you get to visualize all internal variables, and choose to change their value: this way, you can effortlessly simulate different situations.

Comprehensive Spice simulator that can handle various analysis modes

MacSpice is able to perform different types of analysis: DC, AC Small-Signal, Transient, Pole-Zero, Small Signal Distortion, Sensitivity, or Noise. The tests can be performed for different temperatures, and MacSpice is applying the Spice algorithm to converge a solution.

To help you make the most out of the MacSpice capabilities, the developers also provide a comprehensive user guide that provides details about all the parameters assigned to the built-in models and devices.

Learning tool that can be used to analyze and test the performance of electric circuits of various complexity levels

MacSpice offers you the possibility to access the Spice electric circuit simulator from your Mac: the app provides support for most of the basic Spice functions, but also includes fixes, improvements, and optimizations.

MacSpice is an electronic circuit simulator. Circuit simulation is a way of building and testing virtual models of electronic devices. It is usually cheaper and quicker to simulate a design than to build a prototype. MacSpice uses a text-file 'netlist' description of the circuit as input. This is a list of components and the nodes they connect to. Users may prepare netlists with a text editor, or derive them from a circuit diagram using a third-party schematic-capture application. MacSpice then builds a numerical model of the circuit and analyses this.

Free Spice Simulators For Windows

A command interpreter (shell) is used to specify the types of analyses that are required and how the results should be processed, saved or displayed. The high quality of the MacSpice command interpreter makes the automation of tasks straightforward.

MacSpice runs on Intel architecture Apple Mac computers. It is compatible with Berkeley Spice 3f5 but incorporates many improvements - from simple bug-fixes to entirely new commands, algorithms and solution strategies. For example: the memory leaks that affected Spice 3f4 have been cured; new algorithms have been developed to facilitate the simulation of large circuits, and to reduce simulation time; MacSpice provides a robust multi-parameter optimizer and facilities for inter-process communication with other applications.
