LogicSim is a simulation tool for digital circuits. It has been programmed until 2009 by Andreas Tetzl until version 2.4 and this version is hosted on https://www.tetzl.de/java_logic_simulator_de.html. In 2020 LogicSim has been reprogrammed by Peter Gabriel ([email protected]) to enhance the program and get rid of old techniques (e.g. applets).

The code is nearly entirely new - a object hierarchy has been designed to make the program more expandable.

The old program used the serialization technique to persist circuits. This has been replaced by a XML-format to describe circuits and modules. Unfortunately old files written with LogicSim2 cannot be used with LogicSim3.

If you just want to start LogicSim3:

1. download the current binary distribution (ZIP) from the github-releases-folder.
2. unzip the file
3. double-click LogicSim.jar
4. If this fails, use the bat-file on Windows or start the jar via terminal or console: (go to the folder first) javaw.exe -jar LogicSim.jar

1. checkout the project
2. setup your IDE so that "src" will be recognized as source-folder
3. start App.java in logicsim-package
4. build your distro via ant-file build.xml
5. if you fix something, contact me so that we can set you up as contributor

create the jar and complete distribution file via ant-build. In the ant file the manifest will be added which is necessary for any jar.

There is only very sparse documentation about this project - and only in German! Please experiment with the functions. The manual is in the manual-subfolder in the project and will be revised soon.

For issue tracking, there is a tracking system on github. It would be nice if you report a bug. An email to the author is also ok.
