Overview

Boundary Scan Testing / JTAG is fast becoming a normal test platform for digital assemblies.  It is essential that the JTAG test ports are designed into the board and thought is given to routing signals out and in via analogue/ interconnects to improve coverage.

Programming and interfaces are relatively inexpensive and the system is normally reasonably production friendly if fixtures are produced that can withstand plugging in and out on a continual basis.
