Logisim, a graphical design and simulation tool for logic circuits, is now at version 2.6.2. This new version fixes numerous bugs from the previous release, while also adding a complete translation into Brazilian Portuguese and a preliminary German translation of the documentation, as well as several minor enhancements.
Most enhancements revolve around preferences. Some preferences that were previously stored as options are now stored as application preferences, and the preferences window has been reorganized a bit to reflect this. Perhaps a bigger feature is that Logisim now attempts to remember your window state - such as tick rate, zoom factor, and window size - so that on startup it restores the appearance it had when you last exited. It also adds a new Open Recent submenu into the File menu, allowing access to the most recently edited projects without needing to find anything through the dialog box.
Another enhancement new to this feature is that Logisim can be configured to display the actual tick rate. This will often be much smaller than the actual tick rate, because Logisim will not perform a tick until it has completed propagation for the current tick. To show the actual tick rate, go to the Windows tab of the Preferences window.
Educational institutions around the world use Logisim as an aid to teaching about digital logic and computer architecture. As a Java application, Logisim can run on most major operating systems.
