LTspice is not available for Linux but there are plenty of alternatives that runs on Linux with similar functionality. The best open source Linux alternative is KiCad. If that doesn't suit you, our users have ranked more than 25 alternatives to LTspice and 11 are open source and available for Linux so hopefully you can find a suitable replacement. Other interesting open source Linux alternatives to LTspice are QUCS, Circuit JS, Ngspice and Qucs-S.
KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...
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.
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.
Ngspice is a 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.
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.
OpenModelica – A Free Modelica Environment! OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OS.
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.
Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.
oregano - An electrical engineering tool for GNOME
oregano is an application for schematic capture and simulation of electronic circuits. The actual simulation is performed by Berkeley Spice, or GNUcap or the new generation ngspice which is required for simulation, but not neces.
