Description

The IEEE 1149.1 standard developed by the Joint Test Action Group (JTAG) provides a framework for a structured test approach to improve IC and board level testing while eliminating after-the-fact test approaches. This document previews three integrated circuits (ICs) a test bus controller (TBC) a SCOPE scan path selector (SPS) and a SCOPE digital bus monitor (DBM) that support the standard for
