6-Port JTAG Gateway
Description
The AS91L1006BU is a one to 6-port
JTAG gateway. It partitions a single JTAG chain
into six separate chains. These separate chains
can be optionally configured to operate as a single
chain.
The AS91L1006BU device is used to
provide enhanced capabilities to the standard
IEEE1149.1. It enables the IEEE1149.1 interface
to be used in a true Multi-Drop environment without
any additional signals. This Multi-Drop capability
enables the standard IEEE1149.1 interface to be
used not just for stand alone PCB (Printed Circuit
Board) testing, but also for complete system
testing including all PCBs within a system back
plane environment.
The AS91L1006BU provides the capability
of partitioning the PCB, into multiple smaller
IEEE1149.1 scan chains totally under software
control. Partitioning the IEEE1149.1 chains on the
PCB has several benefits which include easier
fault diagnostics capabilities as a fault on one of
the IEEE1149.1 Local Scan Ports (LSPs) does
not render the PCB untestable, faster flash
programming on the PCBs, and removal of
IEEE1149.1 signal loading issues.
All of the protocols required for
addressing the AS91L1006BU device via the
Multi-Drop capability and the protocols for
configuring which of the six IEEE1149.1 LSPs on
the AS91L1006BU are to be used, is handled via
3rd party ATPG tools from vendors like AssetIntertech and JTAG Technologies. In a Multi-Drop
environment it is also possible to perform
interconnect tests between multiple PCBs within a
system thus extending the interconnect tests to
the back plane itself.

AS91L1006BU
AS91L1006BU Gateway Functional Description
The basic structure of the AS91L1006BU
device is shown in Figure-1. The core of the device
is the 16-state IEEE1149.1 TAP controller state
machine. All accesses to the internal registers of
the AS91L1006BU device are controlled via this
state machine during normal operation as per the
IEEE1149.1 standard. The address selection logic
enables the AS91L1006BU to operate in a MultiDrop environment within system backplane.
The address selection logic compares the
scanned address to the slot address value
presented on the I/O of the AS91L1006BU device.
The LSP park/unpark logic provides control
through instructions scanned in under the
IEEE1149.1 protocol, to select, which LSP will be
placed into the active, scan chain. The passthrough and LSP connection logic selects the
signal paths for the LSP IEEE1149.1 signals. The
Selected Single
Device
Figure-2 shows the device selection state
machine. The AS91L1006BU will perform an
address compare on the slot address presented
at its I/O and the value scanned in via the
IEEE1149.1. If the value matches then the
AS91L1006BU becomes selected and is ready for
normal access via IEEE1149.1 commands. If the
address does not match then the device will
proceed to the unselected mode, where it will
remain until the AS91L1006BU is issued a
GOTOWAIT instruction or a reset occurs via
TRST or the LSP_RESET pin.

AS91L1006BU Detailed Mode of Operation
Addressing the AS91L1006BU device
After a Test-Logic-Reset or power-up, the
AS91L1006BU device will be in its Wait-forSelection state with its TDO pin tri-stated, thus
avoiding contention in a Multi-Drop environment.
The AS91L1006BU device will respond to a
device-select sequence for a particular address
that is auto generated by third party test tools with
respect to the address that is pre-loaded on its
S(5..0). Once this sequence has been completed,
the AS91L1006BU device will respond to normal
IEEE 1149.1 instructions. Note that addresses 6063 have been reserved and the AS91L1006BU
device will not respond if the user selects these
addresses.
The AS91L1006BU device should be in
the Wait-for-Selection mode, which can be
entered into by issuing an asynchronous reset
(through the deassertion of TRST) or by issuing a
synchronous reset (through the assertion of TMS
for five cycles of TCK). After the device has been
selected, it can be issued a GOTOWAIT
instruction.
The internal IEEE1149.1 state machine of
the AS91L1006BU device is taken to the Shift-IR
phase and the required Device-ID is shifted into
the Instruction register. As the IEEE1149.1 state
machine passes through the Update-IR phase,
the address is matched to the value on the S(5-0)
pins on the AS91L1006BU device; if the values
match, then the AS91L1006BU device is selected
and is ready to receive any normal IEEE1149.1
command.

SELF_TEST Register
The AS91L1006BU device supports a
single output pin that can be controlled via the
IEEE1149.1 interface. When the instruction is
loaded into the AS91L1006BU instruction register,
a single bit data register is connected which is
always reset to logic zero when the TAP state
machine enters Capture-DR. This will cause the
SELF_TEST pin to pulse low for one cycle of TCK,
during the Update-DR phase. This low going pulse
can be used to initiate self-tests on PCB’s in a rack
via the JTAG interface.
internal registers to be reset. In order to enable
async reset tests on LSPs, the test tool should
instruct the device to toggle the LSP reset pins
while maintaining the set up information in the
AS91L1006BU. When the instruction is loaded
into the AS91L1006BU instruction register, a
single bit data register is connected as the data
register which is always reset to logic zero when
the TAP state machine enters Capture-DR. This
will cause the LSP TRST pins to pulse low for one
TCK cycle, during the Update-DR phase.

Pass Through Support within the AS91L1006BU Device
The AS91L1006BU device supports a
Pass-Through mode where the primary or master
IEEE1149.1 JTAG signals can be routed to any
one of the LSPs. When this mode is activated, the
“Debug Enable” signal for that LSP will go active,
which can be used to place a processor such as
the MPC8260 into BDM (Background Debug
mode), if required. If no processors are present in
the LSP, the Pass-Through mode can be used to
assist in the generation of the test vectors or
memory tests for the devices that are linked into
the selected LSP. The pass-through feature has
the effect of simplifying the test vector generation
for the LSP, as it also has the effect of removing
the AS91L1006BU device from the test vector
generation process.
