jtag boundary scan

Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit. Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit. The Joint Test Action Group (JTAG

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.

Boundary Scan, JTAG, IEEE 1149 Tutorial – a summary, overview or tutorial of the basics of what is boundary scan, JTAG, IEEE 1149 (IEEE 1149.1), test system used for testing complex electronic circuits where there is limited test access.

What Is Boundary-Scan?

JTAG (Joint Test Action Group) is originally a name of an organization which standardizes testing for semiconductor devices and PC boards. It also means the standards themselves which have been determined by the organization. JTAG (Boundary Scan) test
