Logisim, a graphical design and simulation tool for logic circuits, has now reached version 2.0.6. This new version repairs three fairly minor bugs identified by Logisim users: Logisim previously was intolerant to opening files saved by versions of Logisim using newly added components/tools, even if the circuits did not themselves use the components. The RAM component erroneously stored a value when it was told both to load and to store a value. And the files created when exporting GIFs were not properly closed once the exporting was complete.
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.
