Table 12: Boundary Scan Instructions
Bit Sequence
The bit sequence within each IOB is: In, Out, 3-state. The
input-only pins contribute only the In bit to the boundary
scan I/O data register, while the output-only pins contributes
all three bits.
The first two bits in the I/O data register are TDO.T and
TDO.O, which can be used for the capture of internal sig-
nals. The final bit is BSCANT.UPD, which can be used to
drive an internal net. These locations are primarily used by
Xilinx for internal testing.
From a cavity-up view of the chip (as shown in the FPGA
Editor), starting in the upper right chip corner, the boundary
scan data-register bits are ordered as shown in
The device-specific pinout tables for the Spartan/XL devices
include the boundary scan locations for each IOB pin.

BSDL (Boundary Scan Description Language) files for
Spartan/XL devices are available on the Xilinx website in
the File Download area. Note that the 5V Spartan devices
and 3V Spartan-XL devices have different BSDL files.
Including Boundary Scan in a Design
If boundary scan is only to be used during configuration, no
special elements need be included in the schematic or HDL
code. In this case, the special boundary scan pins TDI,
TMS, TCK and TDO can be used for user functions after
configuration.
To indicate that boundary scan remain enabled after config-
uration, place the BSCAN library symbol and connect the
TDI, TMS, TCK and TDO pad symbols to the appropriate
pins, as shown in
