This is an italian fork based on the original Logisim version.






Why you should use Logisim ITA :

  • No retro-compatibility problems with old .circ files
  • A lot of new components and small changes
  • Bug fixes and optimizations
  • Constantly supported and listening to all your suggestions/reports

Bugs :

All the original Logisim's bugs we haven't fixed yet :

  • Some random blue/red line caused by bad values refresh
  • Some problem with high frequencies
  • String attribute not calling attributechanged method while writing its value

Programmable Generator: trying to edit its values by clicking on "(click to edit)" is a bit buggy, use "Edit Contents" instead in menu by clicking with right mouse button

Features we want to add :

  • Solve dirty points when rotating
  • Add a new type of library
  • Draw also in circuits
  • Suggest us everything at

Retro-compatibility :

Due to a bug in the original Logisim, wide gates with 4 inputs had a bad pin positioning. I fixed this problem but if you open an old file containing gates with those attributes, its inputs will be disconnected and a warning message will appear

EXE and JAR downloads + microprocessor project :

All in our website

How to compile & use :

The project uses maven, from Logisim/Logisim-Form run mvn package or use your ide and import the directory as a maven project, the output file is target/Logisim-jar-with-dependencies.jar

If you use ecplise, or a older version of Logisim:
Watch our tutorials on "TUTORIAL" section of our website

Translation :

New strings are translated really bad (Google Translate) because i just know Italian and English.

You can help me translating other languages or adding a new one, if you want so, contact me at
