In some cases, engineers may need to access an individual ... 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”.

A quick understand of what is boundary scan testing using IEEE 1149.1 … The boundary scan architecture provides a means to test interconnects (including clusters of logic, memories, etc.) without using physical test probes; this involves the addition of at least one test cell that is connected to each pin of the device and that can selectively override the functionality of that pin. Each test cell may be programmed via the JTAG scan chain to drive a signal onto a pin and thus across an individual trace on the board; the cell at the destination of the board trace ca…
