8.1 Introduction
"Vega 10" has a JTAG 1149.1 compliant TAP controller. The boundary scan implementation is
IEEE compliant. The implementation supports BYPASS, EXTEST, and PRELOAD instructions.
A BSDL file for each of the modes can be obtained from the AMD OEM Resource Center.
8.2 Boundary Scan
The "Vega 10" boundary scan can perform board-level capture and drive out on all
pins mentioned in the BSDL file.
