An environment targeted to e-learning of test issues in microelectronics is presented. The environment consists of a set of Java applets, desktop applications and of a web based access to the HW equipment which can be used in the classroom, for learning at home, in laboratory research and training, or for carrying out testing of students during exams. The tools support university courses on digital electronics, computer hardware, VLSI design and architectures, testing and design for testability to learn by hands-on exercises how to design digital systems, how to make them testable, how to build self-testing systems, how to generate test patterns, how to analyze the quality of tests, and how to localize faults in hardware.
