A transparent solution for providing remote wired or wireless communication to board and system level boundary-scan architectures

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
