POLITECNICO DI TORINO Repository ISTITUZIONALE Testing Embedded Memories in Telecommunication Systems / Barbagallo S.; Benso A.; Chiusano S.; Lobetti Bodoni M.; Prinetto P. Extensive system testing is mandatory nowadays to achieve high ABSTRACT product quality. Telecommunication systems are particularly sensitive to such a requirement; to maintain market competitiveness, manufacturers need to combine reduced costs, shorter life cycles, advanced technologies, and high quality. Moreover, strict

This article analyzes major problems related to testing complex telecommunication systems, with particular emphasis on their memory modules, often so critical from the reliability point of view. In particular, advanced BET-based solutions are analyzed, and two significant industrial case studies 0163-6804/99/$10.00 0 1999 IEEE IEEE Communications Magazine June 1999
