1 Free electronic circuit simulators for electronic design and analysis

Electronic circuit simulator is computer software that will allow us to design and simulate schematics, electronic projects, circuit designs, and circuit analysis without doing in any actual construction and testing.
Electronic Circuit simulation is very helpful to designers, hobbyists, and students in designing and analyzing the response, behavior and waveforms of circuits without spending money and more time. Since simulation takes place virtually, you can transform your computer into an electronics laboratory where you can design and test circuits.
The compilation of  free electronic circuit simulators bellow is useful in designing your electronic projects. Some are totally free to download and free trials.

PSpice Schematics 9.1 a free Student version  of electronic circuit simulator PSpice. Very useful in electronic circuit design and analysis  but have some limits

LTspice IV a free electronic circuit simulator where you can have schematic capture and waveform viewing. You can also design circuits by simply drag and drop.

Quite Universal Circuit Simulator    free circuit simulator software that  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.

TinyCAD  is a program for  circuit diagrams or  schematic drawings. It supports PCB layout programs with several netlist formats and can also produce SPICE simulation netlists.

5Spice  provides Spice specific schematic entry, the ability to define and save an unlimited number of analyses and integrated graphing of simulation results. Plus easy inclusion of Spice/PSpice® subcircuits from a user expandable library. The focus is on analog circuit analysis and circuit design at the component level.

NGSPICE  project aims to improve the spice3f5 circuit simulator.

LogicCircuit an Educational software for designing and simulating logic circuits, with intuitive GUI, hierarchical circuits and multi bit buses, oscilloscope, and navigate running circuits hierarchy.

ZSPICE is a simple reconfigurable spice simulator. Its device library is created using adms
