This paper presents a virtual laboratory for digital design, specifically conceived for educational application and for supporting project work both locally and at distance: the Deeds. It covers combinational and sequential logic networks, finite state machines, microcomputer interfacing and programming at assembly level. The virtual lab is based on three simulator integrated together, combined with a large repository of application projects, available on the web. The paper contains an example of a laboratory session, structured accordingly to the Project Based Learning methodology.
