Requirements and Restrictions
You should review the general requirements and restrictions of 1394 Bus support
in the information on basic operations.
You should also review electrical, environmental, and mechanical specifications
in the Specifications chapter in this manual as they pertain to your system under
test, as well as the following descriptions of other support requirements and
restrictions.
Getting Started
System Clock Rate
Merged Module Pair
The TMS 871 support package can acquire data from the 1394 bus operating at
speeds of 100, 200, or 400 Mb/s.
If you have a pair of modules that are merged in the logic analyzer, you can
un-merge them (and use either one). If you want the modules to remain merged,
then the probe adapter must connect to the master module.
Connecting to a System Under Test
To connect the logic analyzer to the probe adapter, follow these steps:
CAUTION. Static discharge can damage the probe adapter, the probes, or the
module. To prevent static damage, handle all of these products only in a
static-free environment.
1. Plug the power supply into an appropriate power source.
2. Connect the DC plug to the probe adapter to provide power to the probe
adapter.
3. Connect the P6434 probes to the 1394 probe adapter. Align the probe tip with
the mating connector and gently connect as shown in Figure 1–2.

Figure 1–2: Connecting the cables to the probe adapter
CAUTION. Incorrect handling of the P6434 probe while connecting it to the probe
adapter can result in damage to the probe or to the mating connector on the
probe adapter. To avoid damaging the probe and probe adapter, always position
the probe perpendicular to the mating connector and gently connect the probe.
4. Connect the module ends of the P6434 probes to the corresponding connec-
tors on the logic analyzer. The probe module ends are keyed.
NOTE. The right-side P6434 probe (as seen from the rear of the probe adapter)
connects to D1–D0 and C3–C2 connectors on the logic analyzer. This may not
match the color coding on a pre-labeled P6434 probe.
5. Connect the 1394 probe adapter to the 1394 system under test using the 6-pin
1394 cable supplied with the probe adapter, or any standard 6-pin 1394
cable. Use any of the three ports on the front of the probe adapter.
6. The complete test setup appears in Figure 1–3 on page 1–5.

Remember that the information in this section is specific to the operations and
functions of the TMS 871 support package. Information on basic operations
describes general tasks and functions.
Before you acquire and display data, you need to load the support and specify
setups for clocking and triggering as described in the information on basic
operations. The support provides default values for each of these setups, but you
can change them as needed.
Channel Group Definitions
The software automatically defines channel groups for the support.
Channel Groups
The defined channel groups are Data, Speed, Type, Event, Error, Count,
Last_Data, Phy_Data, and Phy_Ctrl.
To see which signal is in which channel group, refer to the channel group
assignment tables beginning on page 2–2. Tables 2–2 through 2–6 show the
channel assignments for the setup.

Trigger Setups
The signals available on the 1394 bus allow for many triggering possibilities.
The .tla files include trigger setting examples, which will be similar to the
example shown in Figure 2–1 on page 2–8.

Acquiring and Viewing Data
Figure 2–1: Trigger Setup Window
This trigger/capture state machine model can be used for a wide variety of
situations. In this example, the default is to store everything with the State 1
being used to identify certain packet types by a specific tcode bit pattern in the
first quadlet of the packet. The Last_Data group is TRUE only on the last quadlet
which allows State 2 to exclude (not store) the entire packet identified in State 1.
In this example, all Cycle Start packets are excluded from being stored and the
logic analyzer is triggered on an Isochronous packet.
Note that the custom clocking options also allow the user to not store long packet
data, gaps, and errors. As there is a limit to the number of clauses in a trigger
state (typically 4), the custom clocking option should be examined for more
complex triggering/storage situations.
Using the model shown in Figure 2–1, some variations useful to 1394 might be:
H Group Speed (symbolic). Can exclude packets labeled with a speed code. For
example, all 100Mb/s packets can be excluded. State 2 is not needed.
H Group Event (symbolic for event). Singles out specific types of qualifying
events. Overlaps custom clocking for gaps and errors. Useful for identifying
trigger point, such as triggering on a bus reset.
2–8
TMS 871 1394 Bus Support Package Instruction Manual
Acquiring and Viewing Data
H Group Count>n. Can be used to store only the first n bytes of the packet.
State 2 is not needed. Note that this is covered for a value of 16 by a custom
clocking option.
H Type (symbolic for type). Allows broadcast, self-id packets, or iso packets to
be excluded. For more information, refer to Tables 3–7 and 3–13 on pages
3–6 and 3–8 for a description of the signals in this group. State 2 is not
needed.
H Group Count=1 and Group Data=(symbolic for tcode). Allows various
packet types to be excluded from storage. Used with State 2.
H Group Error=(symbolic for error). Singles out a specific type of error to not
store or to trigger on. State 2 is not needed.
H Group Count=n and Group Data=HEX. Generic way to specify a packet by
information known to be in a certain byte. For example, the destination
address which is the first 16 bytes of the first quadlet for several different
packet types. Used with State 2 to exclude capture from the identified
quadlet through the end of the packet.
Custom Clocking
Clocking Mode
The TMS 871 will add the selection 1394 to the Load Support Package dialog
box, under the File pulldown menu. Once the 1394 support has been loaded, the
Custom clocking mode selection in the logic analyzer Setup menu is also
enabled. Custom will be the default selection whenever the 1394 support has
been loaded.
When Custom is selected, the TMS 871 support will modify the Custom
Clocking Options menu to display three options:
H Clocking Mode
H Quadlet Capture
H Packet Truncation
The selections for these three options are defined below.
The Clocking Mode option allows the user to select either Normal or Raw Phy
modes of clocking. Normal mode is used for disassembly and for all groups
except Phy_Data and Phy_Ctrl. In Normal mode, different clock options are
available.
Raw Phy mode clocks at twice the rate of Normal mode (the Phy-Link SCLK
signal rate) and is used for acquiring the low-level Phy_Ctrl and Phy_Data group
signals only. Because of the different clocking, other group values may or may

not be valid when acquired. Raw Phy mode is not useful for disassembly. When
this mode is selected, the settings of the other two clocking options have no
effect.
Quadlet Capture
Packet Truncation
There are four quadlet capture selections possible, listed below. These only take
effect when the Clocking Mode is set to Normal. The All Valid selection is the
default.
H All Valid. The all valid selection qualifies quadlets for acquisition by looking
for a Data_Rdy, Arb_Gap, Sub_Gap, Ack_Rcvd, HW_Error, or Reset signal
in the Event group (see Table 3–8 on page 3–6). This selection captures all
the valid quadlets which include gaps, acks, and errors.
H All Valid, no gaps. Same as All Valid except Arb_Gap and Sub_Gap events
are not captured.
H All Valid, no errors. Same as All Valid except errors (HW_errors) are not
captured.
H All Valid, no gaps or errors. Same as All Valid except no gaps or errors are
captured.
There are two selections possible here: None and After 16 quadlets. None is the
default. These only take effect when the Clocking Mode is set to Normal.
H None. There is no attempt to truncate packets.
H After 16 quadlets. Only quadlets up to and including the 16th quadlet in each
packet will be captured in this mode.

Probe Adapter Description
The probe adapter consists of an enclosed unit with three 6-pin connectors for
1394 Bus connections, and two 34-pin connectors for the LA interconnect (via
P6434 probes). Power is provided by an external power supply that plugs into the
back of the probe adapter. Signals from the 1394 Bus cable flow into the probe
adapter and through the P6434 probes to the logic analyzer.
All probe adapter circuitry is powered from an external power supply which must
supply 5-15 volts DC, at 350 milliamps maximum. The adapter has an internal
fuse and circuitry which protects against damage from reversed-polarity power
supply connections.
The probe adapter contains 3-port, 1394a-compliant PHY circuitry. The probe
adapter, following 1394 protocols, causes a bus reset when connected, when it
arbitrates for a node on the bus. Once connected, the probe adapter does not
generate any traffic from the Link layer, and does not expect any traffic to be
addressed to it.
After connecting, the probe adapter monitors all PHY-link data and conditions
the data with an on-board FPGA to generate signals for acquisition and triggering
by the logic analyzer.
The signals presented by the probe adapter to the logic analyzer are TTL level
with a clocking speed of 50 MHz or less. The probe adapter does not cause
excessive loading on critical signals.

Probe Adapter Circuit Description
The probe adapter contains a three-port, 1394a-compatible, commercial PHY
chip to connect to the 1394 bus system under test and to monitor bus traffic. An
on-board FPGA conditions the PHY-Link signals for acquisition and display by
the logic analyzer. The probe adapter uses an external power supply to furnish
the 5 volts necessary to power the circuitry. An internal, resettable thermal fuse is
used for circuit protection. You can monitor the system clock signal (PHY-Link
SCLK/2) to verify the circuitry is active when the probe adapter is on.
Equipment Required
Table 4–1 lists the equipment you will need to verify circuit operation. You can
use an oscilloscope to check the system clock presence, or view the signal
activity if a logic analyzer is available.

Functional Verification
Verifying Clock Activity Using an Oscilloscope
For verifying the probe adapter functionality, there is a diagnostic test point
connected to the SysClk signal which may be used with an oscilloscope to
determine basic operation of the PHY and link chips.
Use the following procedure to verify clock activity in the probe adapter:
1. Plug in the power supply and connect the power jack to the circuit board.
2. Verify the green LED on the front of the probe adapter is lit. If it is not lit,
either power is not being supplied correctly to the probe adapter or the probe
adapter is defective. See Troubleshooting on page 4–4.
3. To access the interal test point, remove the two philips screws accessible
from the bottom of the probe adapter case.
4. Remove the top half of the probe adapter case, exposing the top of the circuit
board.
5. Connect an oscilloscope probe to the SCLK/2 test point. See Figure 4–1.
4–2
SCLK/2
SCLK/2 test point
Figure 4–1: SCLK/2 (system clock) signal test point
6. Verify that a TTL-level square wave signal at about 25 MHz is present.
Absence of this signal indicates the circuit is not operating correctly. See
Troubleshooting on page 4–4.
Note that SCLK/2 is the system clock, and it must be active for the custom
clocking feature to acquire any data at all.

Verifying Probe Adapter Functionality with the TLA System Activity Monitor
If you have a logic analyzer, module, and probes are available, use the following
procedure to verify the probe adapter functionality:
1. Plug in the power supply and connect the power jack to the probe adapter.
2. Verify the green LED on the front of the probe adapter is lit. If it is not lit,
either power is not being supplied correctly to the probe adapter or the probe
adapter is defective. See Troubleshooting on page 4–4.
3. Power on the system and load the 1394 support from the logic analyzer
application. The probe adapter should not be connected to a 1394 bus system
for this test.
4. Connect the logic analyzer module to the 1394 probe adapter with two P6434
probes. Note that one P6434 connects to A3–A2 and A1–A0 and the other
P6434 connector connects to C3–C2 and D1–D0 as indicated on the probe
adapter rear panel.
5. Using the supplied 1394 cable, connect any two of the three 1394 ports
together to form a 1394 bus loop.
6. Wait for 1 or 2 seconds and then disconnect the cable from both ports.
7. View the activity window in the setup window of the TLA 700 application.
Look for an activity pattern as shown in Figure 4–2. Deviations from this pattern
indicate the probe adapter circuitry is not operating correctly or there may be a
problem with the logic analyzer probe hookup. Note that CK0 is the system clock
and must be active for the support’s custom clocking to acquire any data at all.

Troubleshooting
If the probe adapter does not appear to function, and the cable and probe
connections appear good, you may have a power supply problem. Perform the
following steps to verify the power supply is working:
1. Disconnect the power supply from the back of the probe adapter.
2. Check the output with a DMM-it should measure 5 volts.
If the power supply does not measure 5 volts, replace it and verify the probe
adapter functions correctly.
If the power supply is not the problem, the fuse inside the probe adapter might be
tripped. Do the following steps to reset the fuse:
1. Disconnect the power to the probe adapter.
2. Wait 3 or 4 seconds.
3. Reconnect the power to the probe adapter.
4. If the green LED is lit, retest the probe adapter, using either the Oscilloscope
or the Activity Monitor checks. If the probe adapter still does not work, the
probe adapter unit might be defective. Contact your local Tektronix service
center.
5. If the green LED is not lit, and the power supply is not the problem, the
probe adapter unit might be defective. Contact your local Tektronix service
center.
If the square-wave signal is absent when performing the oscilloscope check, the
probe adapter unit might be defective. Contact your local Tektronix service
center.
If the Activity Monitor check fails, the probe adapter unit might be defective.
Contact your local Tektronix service center.
