  • An open source program that works, does what I want, with 95+% of the features I want. Using this amazing tool I have been able to create a fully functioning logic gate based simulation of a primitive 8 bit CPU, based on the Little Man Computer concept, with a terminal peripheral, for my students to learn how CPUs work.

  • if you want any advice on how to use this program pls contact gülbik

  • Just tried this out to follow my son's digital electronics tutorial for myself and to recall things learnt long ago during my degree course. Very easy to pick up and works very well. Shame that it is no longer supported.

  • amazing good and free ;-)

  • Good digital logic teaching tool. Easy to use and, most importantly, easy to understand. Good job. Wish I had this 50 years ago. Now I want an Android tablet app... covering iOS devices would be extra good, too. Then all that my students would need in class are their tablets or phones. Laptops optional.

  • This is a greate software for leaning logic cicuits. Actually, I'm using it as class material for Introcution to Computer right now. Thand you for the work! It would be nicer if the tutorial is available in PDF format on this site.

  • Really great project! - Alas, also abandonware! :-(

  • Absolutely perfect software. Very easy to start using with so good interface. For hardware experimenter and hacker, can work as best software tool. As bonus, he's not platform independent. Thank You very much for work and for making this software free.

  • When you see an option for "plain" or "blank" template, leave it alone!! Logisim will NOT start next time you use it. Deleting and reloading logisim doesn't work. There is a little discussion about this problem but nothing helpful. I've been without for a couple weeks now and I'm beginning to think that if I want to use logisim again it will have to be on a different computer, I am bummed!

  • Very good SW, but many errors: - 3+ inputs XOR gate incorrect output (e.g. 3x ones, output give ZERO or 3+ ones on inputs always give ZERO) - while moving block, wire lines are blue and Logisim must be restarted (reloaded circuit) ... EDIT: XOR have setting for working "correctly"

  • Can anyone help me with "reverse of string" project..I was not able to identify two components.. Can anyone upload the finished project(.circ)file? Help would be much appreciated..

  • We use this software in school and its very easy to learn logic circuits! Great job! Keep it up.

  • Great staff, tnx

  • Thanks for great project! Simply the best.Good,good,good.+1

  • very good project, thanks!Good,good,good.+1

  • I use this software. Thank you for your work.

  • Why must the manual be online? Isnt it best to have an offline manual, like in a PDF? Does the latest release have such a manual with it? Must I install the program to find that it has no manual except the online manual? My point is I dont want use the connection to nor can I count on being able to go online with absolute certainty. If I could not go online I would have no manual for the latest release and so could not use it. Online manuals make no sense except it pleases the dev because his or her package is smaller, that is why, correct? I have never understood online manuals. It seems to just be self serving. Yes youre the dev but thousands dont have a manual and cant use your prog. What if someone has no internet access? I know everybody is doing it, but that doesnt make it right. Is that why you did it? Because everyone else is doing it? In this case online manuals alone I feel is a definite blunder. I know everybody is doing it but if everybody jumped off a cliff and died would you follow just because you MUST follow after the crowd, the stupid decieved crowd? Please make an offline maual and attach it to the packed release.
