Softwares para simulação de circuitos elétricos/eletrônicos

LTspice IV - simulando uma fonte CC com diodo zener.

Existem vários softwares que podem ser usados para simular um circuito elétrico ou eletrônico. O site http://www.electronics-lab.com apresenta uma lista bem completa desses softwares. Aqui, vamos destacar alguns deles. Ficaram de fora os "Demo" e que simulam "apenas" circuitos digitais.
  • On-line:

Java Circuit Simulator
Author : Paul Falstad
Licence Type : Freeware
Descrição : This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current.

Author : MuseMaze, Inc.
Website : http://everycircuit.com
Licence Type : Demo
Descrição : EveryCircuit is an easy to use, highly interactive circuit simulator and schematic capture tool. Real-time circuit simulation, interactivity, and dynamic visualization make it a must have application for professionals and academia. EveryCircuit user community has collaboratively created the largest searchable library of circuit designs. EveryCircuit app runs online in Chrome browser and on mobile phones and tablets, enabling you to capture design ideas and learn electronics on the go.

Author : DigiKey
Website : http://www.digikey.com/schemeit/
Licence Type : Freeware
Descrição : Scheme-it is an online schematic and diagramming tool that allows you to create and share technical layouts using your web browser. The tool includes a full set of schematic symbols for building electrical circuits as well as an integrated Digi-Key catalog that supports the insertion of product images and product photos into your designs.

  •   Freeware:

Author : EasyEDA
Website : https://www.easyeda.com

Descrição : Do schematic capture, Spice simulation, PCB Layout online for free, then order high quality PCBs. EasyEDA: the one stop design shop for your electronics projects.

Universal Circuit Simulator
Author : Qucs team
Website : http://qucs.sourceforge.net

Descrição : Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.

LTspice IV
Author : Linear
Website : http://www.linear.com/designtools/software/#LTspice

Descrição : LTspice IV is a high performance SPICE simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. Our enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. Included in this download are LTspice IV, Macro Models for 800f Linear Technology's switching regulators, over 200 op amp models, as well as resistors, transistors and MOSFET models.
