This paper presents the use of partial duplication to on-line test a switching circuit used in a communication system. The test methodology is validated by fault simulation. The final system is fault tolerant because a test cell may replace a faulty cell, whenever diagnosis can be successfully carried out. A prototype of the on-line testable switching circuit has been produced.
