2D Virtual Laboratory for Teaching BCD to Seven-Segment Decoders in Logic Design Classes

This study presents the design and development of a virtual laboratory for the Logic design course. A novel implementation of a BCD to seven-segment decoder is shown, which allows student to connect and verify the behavior of the circuit themselves. This is achieved with the use of virtual LED indicators, visualizing the state (digital zero or digital one) of all sockets of the logic gates. Furthermore, a reference BCD to seven-segment decoder is available, allowing students to compare the behavior of the circuit they connected with it. For the above reasons, the presented virtual lab is applicable in traditional, as well as in distant and lifelong education.
