The IEEE 1149.1 boundary-scan standard has become an increasingly important architecture for overcoming many of the testability issues facing today's complex high density designs. However, it is becoming increasingly difficult in modern systems to gain access to the inherent board level boundary-scan infrastructure through the edge connector. Subsequently it has become imperative that an alternative solution must be found to access the inherent board level boundary-scan infrastructure using the target designs existing serial communication protocol. This paper describes a transparent solution for providing remote access to single board or multi-board boundary-scan architectures, utilizing the existing wired or wireless communication protocol.
