Table C-3 Boundary Scan Components
To use the dedicated readback logic in a Xilinx FPGA, the
READBACK component must be inserted in the input design. The
MD0, MD1, and MD2 components are typically used to access the
mode pins for use with the readback logic but can be connected to
user logic as well. For more information on the READBACK
component, the internal readback logic, and the directional properties
Connects to the BSCAN TDO
output. Provides the boundary
scan data on each low-to-high TCK
transition.
Connects to the BSCAN TMS
input. It determines which
boundary scan is performed.
Connects to the BSCAN TCK
input. Shifts the serial data and
instructions into and out of the
boundary scan data registers.
