JLS is a GUI-based digital logic simulation tool specifically designed for use in a wide range of digital logic and computer organization courses. It is comparable in features and functionality to commercial products, but includes many student and instructor-friendly aspects not found in those products such as state-machine and truth table editors, extensive error checking, and multiple simulation-result views. Students quickly become proficient in its use, enabling them to concentrate on circuit design and debugging issues. The circuit drawing interface is convenient enough to allow instructors to use it for classroom presentations, and circuits can be modified and tested so quickly that it promotes exploring alternatives not prepared for in advance. Its non-interactive (batch) execution capability, with parameter settings, configuration files and textual output simplifies the grading of large numbers of student projects. Full on-line help is built into JLS - just pull down the help menu and select "contents".
