Circuit design software??

Mon Sep 10, 2012 9:24 pm

Can anyone recommend a Windows freeware tool for drawing electronic schematics?? I need symbols for both analog and digital, simulation would be nice but not necessary.

I assume you mean schematic layout tool. If so try Eagle free version. There is no simulation. Finding free simulation tools is more difficult if you require graphical input. Design software implies some of the design is performed by the computer.

I use 'Ideal Circuit' on my windows PC - its simple and free.

Have a look at DesignSpark PCB, it has schematic capture and PCB layout and this some simulation software. It's free just need to register with a email address.

I used it to design quite a few add-on boards for the RPi and Arduino, check my blog

Been searching for that perfect FREE software too, here are some which i have tried (images taken from the source websites):

Online Design and simulation - Circuit Lab
https://www.circuitlab.com/
Image
Not bad for drawing some circuits out, but never quite worked out easy way to run the simulation side of it. Shame, has great potential.

Yenka (the result of the OLD-SCHOOL Croc-Clips)
http://www.yenka.com/
Image
An excellent program, with excellent simulation, although has a very annoying timed free licence so that you can't use it during the day (there may be ways to resolve this, but extra hassle).

Fritzing
http://fritzing.org/
Image
A nice looking program for schematics, breadboard and pcb designs. My main issue with it is that the side view of components (designed to make it easy to see what it is) makes it hard to design compact layouts. Also the stripboard layout (which was my main need) support is limited (track cuts are between holes only, and side view of components make it difficult). The schematics, breadboard and pcb are even linked, so that you can confirm that connections are matching (can be difficult to confirm it is correct though, may be bugs in that aspect). Editing components is also difficult but they are clearly working on that, hopefully they will bring in a top-down view for designing - option to use PCB component view on the layout). Has massive potential, but just doesn't quite work YET.

Stripboard layouts - VeeCAD
http://veecad.com/
Image
This basic looking program in fact is one I like the most... It's main use is for laying out components on stripboards, which is essentially all it does. However, it is simple (once you get used to it - creating components manually and then laying them out) and allows you to layout stripboards and play with the design.
It does support importing of netlists, which is a standard output of a circuit designer such as Sparkfun - although I've not tried this so I don't know how much is available for the free version (details to try this here). So far all the circuits I've done I've just used it for layout and traced through in my head (still easier than using paper, but anything complicated is sure to make your head hurt!).

Android App - EveryCircuitFree
https://play.google.com/store/apps/deta ... free&hl=en
Image
I like this app a lot but unfortunately the free version is VERY limited (you get tiny prototype area) and the full app is expensive for a phone app (although it may be worth it perhaps, since it seems to be quite extensive). In fact, having another try with it, it is superb for basic level stuff, could do with some IC support though.

Hi,

I found another cool one at http://www.DoCircuits.com. This has real looking components and devices.

The source for the Java app is available as well, so if you need to model (for example) oscillators built using schmitt trigger inverters, you can add them yourself.

Thank you everyone who commented on circuit building software I never knew so many existed.
At the moment I've settled for Electronic Workbench it's a little old and lacks some symbols but it's by far the easiest tool to build with.
My only misgivings so far are the massive blobs as wire links and the inability to add new symbols to the parts list like a loud speaker.
In any case I could always improvise with photoshop / gimp missing so it's no skin off my nose :)

One of my reasons for acquiring circuit drawing software is that in time I would like to publish some of my work without relying on hand drawn diagrams.

This leads me to another query, could anyone recommend some good web sites for publishing circuits??

So far http://electroschematics.com/ looks promising but it’s unclear if registered users are only allow permitted to post comments or allowed to publish circuits diagrams as well??

@redhawk - electroschematics.com accepts schematics submission.and is also looking for contributors to write article related to Raspberry Pi. You can use the contact form to get in touch with the administrator. Thank you.

For schematic drawing I have used Dia. Sort of a Visio clone. Has support for custom symbols and a repository for symbols where you can download more symbol libraries.

https://live.gnome.org/Dia

For circuit simulation I use Solve Elec
Works pretty good once you get used to the finicky drawing and parts placement scheme.
(analog only no digital)
- Does AC or DC circuit analysis and shows equations.
- Can add volt and ammeters anywhere in the circuit and make plots.
- Oscilloscope, transfer functions etc.

Unless specified otherwise my response is based on the latest and fully updated Raspbian Buster w/ Desktop OS.

I realize it's been over a year since anyone posted to this; but anyway, I've found gEDA (https://packages.debian.org/stable/electronics/geda) and I'm going to give it a try.

Altium is one of the best (some say the best) circuit design CAD programs for professionals, but it requires very large license fee's, only affordable for companies.

The makers of Altium now have brought out a free design CAD program with similar features as Altium, but only for "open designs", it is called circuit maker, its still in development, but you can express interest in it here:

CircuitMaker is in closed beta.

thats why i said it is still in development, if it comes out of beta it will be available for everybody.
I've signed up for the beta btw.

Just a note about circuit design software running on a Pi 2. I've got gschem and pcb from the gEDA project working on my Pi 2. For gschem working means it's usable as long as the circuit design density is not too great. If you zoom out on a dense schematic, it bogs down. The pcb from the repository uses gl and is too slow to tolerate, but I compiled a pcb binary without gl support and that is happily working very well. I'm now looking forward to a warm day when I can work on my next pcb layout outside on the patio with my Pi 2 attached to an Atrix lapdock.

This was already suggested, but KiCad is getting a lot of attention these days. From what I understand, the foundation has also contributed funding to KiCad development.

I use EasyEDA. Totally web-based, which is nice. There is simulation, but I don't use it. Very easy to make parts, which I also like.
