Logisim, a graphical design and simulation tool for logic circuits, is now available in version 2.0.3. The new version introduces a module for logging simulation results into a file. Additionally, the new version introduces a Probe component into its base built-in library, and it repairs a few relatively minor bugs.
Users of Logisim are invited particularly to comment on the new logging module, which is accessible via Logging... in the Simulate menu. The module has much potential for further development, if interested users suggest how they would like to see it extended.
Logisim is currently used by many colleges and universities around the world to teach concepts about computer organization and computer architecture. Additional information about the program is available at http://www.cburch.com/logisim/. Logisim can be downloaded through SourceForge.net at http://sourceforge.net/projects/circuit/.
