Circuit diagram software anyone?

Click For Summary

Discussion Overview

The discussion revolves around the selection of software for drawing circuit diagrams, particularly in the context of preparing materials for a Circuit Analysis course. Participants explore various tools, their features, and suitability for different levels of schematic complexity.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about software options for drawing circuit diagrams, expressing a preference for not drawing by hand.
  • Another participant recommends OrCAD Capture as an industry standard for schematics, providing a link to download a demo version.
  • Some participants question whether other CAD programs, like ViaCad, can effectively serve the same purpose as OrCAD.
  • It is suggested that basic schematics can be drawn using any CAD software, but more complex designs may require specialized packages like OrCAD or PADS.
  • A free, open-source option called KiCad is mentioned, though its licensing for educational use is uncertain.
  • One participant emphasizes the advantages of using dedicated schematic drawing software over general CAD programs, highlighting features such as connectivity checks and the ability to generate netlists and BOMs.
  • Concerns are raised about the limitations of using programs like Visio for schematic drawing, particularly regarding connectivity information and netlist generation.
  • Several participants mention other software options, including a free tool from Cadsoft and XCircuit, noting their capabilities and limitations.

Areas of Agreement / Disagreement

Participants express differing opinions on the effectiveness of various software options, with no consensus on a single best choice. Some advocate for specialized schematic software, while others believe general CAD tools may suffice for simpler tasks.

Contextual Notes

Participants note that certain software may have limitations, such as restricted features in free versions or uncertainties regarding licensing for educational use.

Who May Find This Useful

This discussion may be useful for electrical engineering students, educators preparing course materials, and hobbyists looking for circuit diagram software options.

Hi,

What do you EE's use to draw circuit diagrams for reports? I'll be teaching a course in Circuit Analysis this summer, and there is no existing lab manual. I'd like to make one, but I don't want to draw the circuit diagrams by hand (I draw like a retard :redface: ).

Thanks,

OrCAD Capture is pretty much an industry standard for schematics.

Can any of the other "CAD" programs work as well. I have ViaCad on my computer, it has a majority if not all of the electronics symbols. Will that work or is there something else that OrCad offers
 
If you just want to draw fairly basic schematics, any CAD software will do. If your schematics will be more complex, you might be better off with a package specifically designed for drawing them, such as OrCAD or PADS. There is also http://www.lis.inpg.fr/realise_au_lis/kicad/ , a free, open-source schematic and simulation package, but I don't know if their license allows use for educational purposes or only for personal use.

Um, you resurrected a 5 year old thread... :rolleyes:

But whatever. I guess the subject of CAD software is timeless, after all.

A schematic drawing package like OrCAD gives you many features that a straight drawing CAD program like Visio or others cannot. It helps you with connectivity issues, via Net Names, connection by names, bus connections, etc. It let's you enter information for parts (like voltage, power, source, price, etc.) that you can access by clicking on the parts. It let's you generate Netlists (for the PCB layout phase), BOMs (bills of materials for the parts ordering), and let's you do Design Rule Checks to find connectivity and other errors.

There are typically Student Versions available for some of the schematic drawing packages. There are also some fairly inexpensive packages like Eagle that work reasonably well.

Once you've used a real schematic entry tool, you will be very frustrated trying to draw even simple schematics in a CAD or drawing program.
 
Not to mention the fact that schematics drawn in programs like Visio contain no real information about connectivity; you cannot convert them into a netlist for a simulator.

But berkeman did mention exactly that.

No, actually I mentioned the PCB layout aspect of the Netlist, not the simulation aspect. Good point by chroot.

I like this software, it's free:

www.cadsoftusa.com

It's been mentioned. In any case, the free version is highly limited, good as it is. They also offer a personal-use version intended for hobbyists for $US150 which has impressive capabilities, including the ability to autoroute a 6x4-inch 4-layer board.
