Using 1149.1 for multi-drop and hierarchical system testing

Abstract

The IEEE 1149.1 boundary scan test standard has been growing in usage since its approval in 1991. As applications developed primarily for board level manufacturing test grow, an awareness and need for using this test infrastructure for system level test and integration has grown. This paper examines the methods of integrating test from design to field service, explore methods for building system level test, and propose some requirements for support and development of these test methods.<>
