7. JTAG Module
The Joint Test Action Group (JTAG) created the boundary-scan testing standard (documented
in the IEEE 1149.1 Standard) for testing printed circuit boards (PCBs). The boundary-scan
approach involves designing boundary-scan circuitry into the integrated circuit. PCBs
populated with 1149.1 compliant devices can be tested for connectivity, correct device
orientation, correct device location, and device identification.
All the pins on compliant devices can be controlled and observed using (typically) five pins
that are routed to the board edge connector. Board designers can develop a standard test for all
1149.1 compliant devices regardless of device manufacturer, package type, technology, or
device speed.
