Ngspice is described as 'Mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Ngspice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to Ngspice for a variety of platforms, including Windows, Linux, Mac, Web-based and Flathub apps. The best Ngspice alternative is Circuit JS, which is both free and Open Source. Other great apps like Ngspice are QUCS, LTspice, Proteus PCB design and EasyEDA.
This is a javascript 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 Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
LTspice IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.
Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.
Schematic capture, Ngspice based simulation, PCB layout, custom PCB manufacturing, for electronic engineers, educators, students and hobbyists.
KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit.
Software for Simulating Voltage and Currents of a text file net-list of a electronics components such as Resistors, Capacitors, inductors, transisters, Diodes, Voltage and Current Sources, etc.
Features a unified workflow for schematic capture, PCB layout, mixed analog/digital simulation, signal integrity analysis, real-time 3D editing, ECAD-MCAD collaboration, component libraries, collaborative design tools, BOM generation, routing, and manufacturing outputs.
This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. It's a desktop version of the Circuit JS.
Qucs-S is a spin-off of the Qucs cross-platform circuit simulator. "S" letter indicates SPICE. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI.
NI Circuit Design Suite software improves the PCB design process by integrating capture, simulation, and layout into a single toolchain with NI Multisim and Ultiboard software.
Multisim is industry-standard SPICE simulation and circuit design software for analog, digital, and power electronics in education and research.
