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 http://www.tetzl.de/java_logic_simulator_de.html. In 2020 LogicSim has been reprogrammed by Peter Gabriel (pngabriel@gmail.com) 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 This has been replaced by a XML-format to describe circuits and modules.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:
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.
