Interactive teaching of elementary digital logic design with WinLogiLab

This paper presents an interactive computerized teaching suite developed for the design of combinatorial and sequential logic circuits. This suite fills a perceived gap in the currently available computer-based teaching software, with the purpose of providing alternative-mode subject delivery. The authors were, therefore, prompted to develop a Microsoft-Windows tutorial suite, WinLogiLab, comprising a set of interactive tutorials that show the link between Boolean algebra and digital combinatorial and sequential circuits. The combinatorial tutorials follow the initial design steps: from Boolean algebra, to truth tables, to minimization techniques, to production of the combinatorial circuit in a seamless way. Similarly, the sequential tutorials can design simple finite-state counters and can model more complex finite-state automata.
