JTAG/boundary-scan is found in most of today’s electronics. The technology was standardized in 1990. Since then more standards have been added each building upon and enhancing the original standard to extend the test coverage of JTAG/boundary-scan.
WHAT IS BOUNDARY-SCAN?
Boundary-scan (also known as JTAG or IEEE Std 1149.1) is an electronic serial interface that allows access to the special embedded logic on a great many of today’s ICs (chips). The JTAG accessible logic serves a number of functions that can include any or all of the following:
JTAG boundary-scan helps your process in three ways: it saves your organization time, it is cost-effective and it strengthens the quality of your products. To explain how we do that, let’s look into some of the details.
