I am looking for recommendations on the best software or websites for drawing equivalent circuit models that are suitable for inclusion in research articles. The tool should allow for precise and professional diagrams that meet the standards of academic publications. Ideally, it should support various components like resistors, capacitors, inductors, and active elements, and offer features for creating clear, readable models. Would you recommend any options that balance ease of use with advanced features, or any specific platforms that specialize in this type of diagram creation?
For drawing equivalent circuit models for research articles, you need tools that provide precision, clarity, and professional-quality schematics. Here are some of the best options:
1. Specialized Circuit Design Software
These tools are ideal for electrical/electronic circuit diagrams:
- LTspice – Free, powerful, and widely used for SPICE simulations and circuit schematics.
- KiCad – Open-source PCB design software with a strong schematic editor.
- OrCAD Capture – Industry-grade tool with advanced circuit modeling capabilities.
- Proteus – Great for both schematic design and simulation, especially for microcontroller-based circuits.
2. General-Purpose Diagramming Tools
These tools are great for clean, presentation-ready circuit models:
- Microsoft Visio – Offers electrical engineering templates and shapes.
- Lucidchart – Web-based alternative to Visio, good for quick, polished diagrams.
- Draw.io (diagrams.net) – Free and easy-to-use for simple circuit diagrams.
- Inkscape – A vector graphics tool that allows precise circuit diagram customization.
- Adobe Illustrator – Professional-quality illustrations, useful for final publication figures.
3. LaTeX-Based Tools for Research Papers
If you prepare documents in LaTeX, these tools integrate well:
- Circuitikz – A LaTeX package for drawing high-quality circuit diagrams within research papers.
- TikZ – Advanced drawing tool in LaTeX, great for custom circuit symbols.
4. Online Tools for Quick Circuit Drawings
For quick and simple equivalent circuits:
- EasyEDA – Free online tool with simulation and export options.
- Fritzing – Good for simple circuits and PCB layouts.
- Scheme-it (by DigiKey) – Online schematic drawing tool with a large component library.
Best Choice Based on Your Needs
- For publication-ready schematics → Circuitikz, Inkscape, Adobe Illustrator
- For detailed simulation and design → LTspice, KiCad, OrCAD
- For quick diagrams → Draw.io, Lucidchart, EasyEDA
For decades, Electronic Design Engineers had to breadboard the electronic components to verify the design works. This commonly took multiple iterations.
SPICE models, since the year 2001, changed this => specifically Micro-Cap..
Micro-Cap does worst case analysis --- changing the tolerances of components --- changing the temperature --- etc. --- interactively. Micro-Cap creates schematics with mixed analog / digital simulator and interactive sketch. It is easy to use. It results in quick designs!
I have used Micro-Cap for all of my electronic designs since 2001. When I tested prototypes, they worked exactly as the Micro-Cap simulated.
All Electronic Design Engineers at Emerson used Micro-Cap, even though it cost $4,000 each. I'm not aware or any other electronic SPICE modeling programs even close to Micro-Cap capability.
Micro-Cap is now free. The owner of Spectrum Software has retired. To download => https://micro-cap.informer.com/12.0/
Micro-Cap video clips are now available via YouTube.
Micro-Cap is an exceptional tool that Electronic Design Engineers will find worth their time!
