Design, Verification, and Application of IEEE 1687

IEEE 1687 (IJTAG) has been developed to enable flexible and automated access to the increasing number of embedded instruments in today´s integrated circuits. These instruments enable efficient post-silicon validation, debugging, wafer sort, package test, burn-in, bring-up and manufacturing test of printed circuit board assemblies, power-on self-test, and in-field test. Current paper presents an overview of challenges as well as selected examples in the following topics around IEEE 1687 networks: (1) design to efficiently access the embedded instruments, (2) verification to ensure correctness, and (3) fault management at functions performed in-field through the product´s life time.
