http://www.ece.uwaterloo.ca/~aplevich/Circuit_macros/ This satisfies pretty much all the requirements, but it would appear some people want a GUI for editing which this does not have inherently, (although KDE interfaces can be found at http://wwwu.uni-klu.ac.at/magostin/cirkuit.html and http://staff.ee.sun.ac.za/pjrandewijk/wiki/index.php/M4_Circuit_Macros_-_Kile_IntegrationLaganne (talk) 18:14, 25 June 2009 (UTC)). It may be a little bit harder to get the hang of, but this would come with all the benefits of LaTeX. Authors would be able to upload their code for a diagram, allowing it to be very easily modified. SVG output is as simple as it is with other TeX/LaTeX files, so that's not a problem. Have a look at the link for ".png files" to see some examples, the links for .m4 files will show the code required. The component library is also larger than pst-circ and the alternatives I've looked at and much better looking, in my opinion. —Preceding unsigned comment added by 124.169.143.22 (talk) 18:47, 10 May 2009 (UTC)[reply]
I've added a couple of circuit diagrams that I made using circuit-macros, just so people can see the final result. The images are SVG so they scale very nicely, but I'm not particularly happy with the blurry lines at the default zoom level. Robert A. Maxwell (talk) 09:54, 27 October 2009 (UTC)[reply]
It may not be pretty, but it does work. Nice find! Care to add it to the feature chart? It doesn't have direct export to SVG, but it does have export to PostScript. Inkscape 0.46 (not yet released, but working pre-release builds are availble) can open PDFs and save them as SVGs. The same basic idea (print to PDF) works for many programs, and with the new Inkscape, it's now easier to get those converted to SVGs. QUCS has the same problem (lack of direct SVG support) except printing doesn't work right in the Windows version (Linux is fine). I filed a feature request to see if the QUCS devs would add a save as SVG option and they seem optimistic about that. TheAmigo42 (talk) 22:57, 9 January 2008 (UTC)[reply]
Circuit Maker60
I removed the information about Circuit Maker60 from the project page because I am unable to find it; the microcode.com website appears to be dead (no response over the course of a week), and Altium Designer does not appear to have a demo version (not to mention that it is way overblown for simple schematic drawings).
