Talk:List of free electronics circuit simulators

Free As In Beer Versus Free As In Speech
Since the opening paragraph of the page states that the software listed is distributed under a free software licence, I recently removed LTspice and PartSim from the list. Maybe we should consider changing this page to list both free and proprietary licensed software? If we do, we should create separate lists for each. AndrewGarber (talk) 07:13, 8 January 2013 (UTC)
 * I agree. I have removed Logisim from the list.
 * I suggest that this page be moved to List_of_circuit_simulators, given the relatively small range of circuit simulation software available, it makes more sense to list both free and non-free together. Chryseus (talk) 22:50, 13 March 2014 (UTC)
 * While you're at it, is it OK to create an article for glogic which some noob broke all the links for? They removed unqualified engineering programs from the GTK apps list, and then didn't bother to make sure nothing was being redirected there.  I don't know why Wikipedia doesn't warn you before letting you remove a referenced section.  I agree that a better list will list all of them and have the license as a column.  That, or separate between freeware and open-source.  73.181.82.26 (talk) 06:53, 26 August 2015 (UTC)
 * Oops, didn't read the article again - seems someone provided separate lists. :) 73.181.82.26 (talk) 06:54, 26 August 2015 (UTC)
 * Free shouldn't be narrowed down to only free software licences, thus I'm removing that description. • Sbmeirow  •  Talk  • 16:09, 19 April 2021 (UTC)

ECAP
Is it too strange to put ECAP on the list? Yes it was discontinued years ago, but as far as I know is the ancestor of the rest. It was distrbuted (I believe freely) by IBM in the 1960's, with versions for at least the 1130, 1620, 709x, and S/360. I believe initially in Fortran II, and later Fortran IV. Source for some versions is available. I have the 1130 version, with a small number of changes, compiled with gfortran. Gah4 (talk) 06:11, 19 June 2021 (UTC)


 * Where is the article for it? • Sbmeirow  •  Talk  • 11:40, 19 June 2021 (UTC)


 * Well, that is the next question. Yes, I think it should have one. I had to actually ask the person who did Spice if ECAP was a predecessor, and it seems yes. Otherwise, it seems to have been lost in the history of circuit simulation, but many of the important ideas started there. Does it not get into the list until it has an article? Gah4 (talk) 00:10, 20 June 2021 (UTC)


 * This list is mainly meant for newer software. It has been months since your comment at Talk:SPICE but you didn't add anything about it in that article or the Electronic circuit simulation article either, as well as haven't created a new article for ECAP too.  If you want other people to know about this historical information, then please move forward with one or more of those.  •  Sbmeirow  •  Talk  • 04:08, 20 June 2021 (UTC)

Other free simulators
The following are free electronics circuit simulators too, but the main reason they can't be added to the table is none of these have an article on Wikipedia. Of the following, I have seen Digital recommended the most on technical social media sites, and I think some colleges are using it, thus it might be the most worthy of a new article. • Sbmeirow  •  Talk  • 11:14, 22 July 2021 (UTC)

Digital
Digital, another digital logic designer and circuit simulator. Includes common 74xx chip library, VHDL and Verilog as well as export circuit to VHDL and Verilog, finite state machine editor, export of SVG vector graphic file, export of JEDEC file for CPLD, support for optional custom logic components written in Java, support for downloading to BASYS3 / Mimas / Mimas V2 boards. • Sbmeirow  •  Talk  • 04:42, 11 January 2020 (UTC)

KLogic
I'm not sure but I think KLogic should be mentioned in the same list as TkGate. Also, it seems there is some type of bug in TkLogic, whereas KLogic works correctly. --212.251.183.156 (talk) 01:00, 24 November 2009 (UTC)

Klogic seems to be no longer maintained. The website still exists, but it gives 500 errors for most links, including downloads. --Trex4321 (talk) 15:30, 29 August 2021 (UTC)

circuitjs
I think circuitjs should be mentioned here.--RolfSander (talk) 15:52, 6 January 2019 (UTC)


 * Can I add a vote to support this. I was adapted by Iain Sharpe (and old colleague of mine, for the sake of full disclosure) from a Java app, but I've found it easy to use, free and fairly accurate. There's nothing like a breadboard (or a PCB come to that) but this does take some of the guesswork out and it offers real-time analysis and scopes with XY functions to name just two things. 82.24.18.184 (talk) 18:48, 21 September 2021 (UTC)


 * Voting isn't the issue, the lack of wikipedia articles is why all of these software programs aren't included (per my comment at the top of this section). •  Sbmeirow  •  Talk  • 06:19, 23 September 2021 (UTC)
 * So seems like the solution is for someone to make a page for circuitjs.
 * I don't have much ability to gauge the noteworthyness of a particular piece of software, but I personally use circuitjs quite a bit to quickly prototype and get in an intuitive sense of how the electrons are moving around in a circuit (when not concerned about getting a SPICE-level of accuracy).
