8.19 JTAG Boundary-Scan
Ibex Peak adds the industry standard JTAG interface and enables Boundary-Scan in
place of the XOR chains used in previous generations of the Ibex Peak. Boundary-Scan
can be used to ensure device connectivity during the board manufacturing process.
The JTAG interface allows system manufacturers to improve efficiency by using
industry available tools to test the Ibex Peak on an assembled board. Since JTAG is a
serial interface, it eliminates the need to create probe points for every pin in an XOR
chain. This eases pin breakout and trace routing and simplifies the interface between
the system and a bed-of-nails tester.
