Instruction Set
The Virtex-E Series boundary scan instruction set also
includes instructions to configure the device and read back
configuration data (CFG_IN, CFG_OUT, and JSTART). The
complete instruction set is coded as shown in Table 6.
Data Registers
The primary data register is the boundary scan register. For
each IOB pin in the FPGA, bonded or not, it includes three
bits for In, Out, and 3-State Control. Non-IOB pins have
appropriate partial bit population if input-only or output-only.
Each EXTEST CAPTURED-OR state captures all In, Out,
and 3-state pins.
The other standard data register is the single flip-flop
BYPASS register. It synchronizes data being passed
through the FPGA to the next downstream boundary scan
device.
The FPGA supports up to two additional internal scan
chains that can be specified using the BSCAN macro. The
macro provides two user pins (SEL1 and SEL2) which are
decodes of the USER1 and USER2 instructions respec-
tively. For these instructions, two corresponding pins (T
DO1 and TDO2) allow user scan data to be shifted out of
TDO.
Likewise, there are individual clock pins (DRCK1 and
DRCK2) for each user register. There is a common input pin
(TDI) and shared output pins that represent the state of the
TAP controller (RESET, SHIFT, and UPDATE).
Bit Sequence
The order 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.
From a cavity-up view of the chip (as shown in EPIC), start-
ing in the upper right chip corner, the boundary scan
data-register bits are ordered as shown in Figure 12.
BSDL (Boundary Scan Description Language) files for Vir-
tex-E Series devices are available on the Xilinx web site in
the File Download area.
