Digital electronic circuits design requires that both exercises and practices be integrated to teaching processes. Most practices are executed over local areas, as specialized laboratory classrooms; however, online education has been strengthened and currently is possible to experiment from remote locations. Some main contributions about online laboratories made by research groups were described in this work; these were focused on digital electronic systems. A developed software tool to remote programming of digital logic functions was described too, which supports the Digital Systems teaching. This tool was designed for local or net-working, and allows users to interact with a tool set for configuring a Cyclone II Field-Programmable-Gate-Array on a DE2-70 development board.
