best free software for electric circuits drawings

The free version serves to promote the paid version, so some of the advanced features are not available in the free version.

The software is developed by SmartDraw LLC that produces CAD and professional design software. SmartDraw – Free software for the electronic schematic design. Sketches drawing, spice simulation, display of waveforms and various other applications are the meaining features of this application. LTSpice– A simulation software developed by Linear. Click the link for a free version of Pspice students.

Pspice – Student Version – Maybe you know Pspice – “the” simulation software. There is no information on the existence of a Windows version. Licensed under the GPL license, is available for Mac and Linux. This software is only suitable for a beginner or a new user to the design of circuits, but it is a good software for the design of block diagrams. Also some important basic components are available. Professionals can perform fast evaluation of a new design, including detailed analysis of complex circuits and systems.Dia – a simple software for the design, suitable for drawing block diagrams. IdealCircuit can be used by student and novices for studying electronics theory. The algorithm is not distracted by convergence problems, inherent to most of SPICE-based simulators. IdealCircuit uses a unique simulation algorithm, which provides fast and reliable simulation with true ideal components. Students can simulate exactly the same schematics they see in the textbooks: no need to select a specific diode or amplifier from the list of thousands of parts. With ideal components, engineers can evaluate a general concept and prove the feasibility of the design very quickly, leaving thorough and detailed analysis to standard SPICE-based tools. However, it is simplified as much as possible: very simple and intuitive interface, fewer components and models, no fancy and powerful features that are only useful for specialized applications. It uses exactly the same unique and robust algorithm as NL5 Circuit Simulator. IdealCiruit is an analog circuit simulator working with true ideal components.
