Web2.3 Boundary Scan Testing Joint Test Action Group (JTAG), created the concept of boundary scan testing as a method to overcome limitations of bed-of-nails testing. IEEE standardized the method and is now known as IEEE 1149.1 specification. Any device that supports boundary scan is sometime referred to as a “1140.1 compliant device”. WebBoundary-Scan testing hm; become the new approach to PCB testing. By taking precautions in the design of the IC (design for testability), testing on PCB level can be simplified 10 a great extent. This condition has been essential for the success of the introduction of Boundary-Sc,m Test (BST) at board level. Webavailable to perform boundary-scan-based tests.
