Support Description
This chapter provides information on the following topics and tasks:
H A description of the TMS 163 microprocessor support package
H Logic analyzer software compatibility
H Your system under test requirements
H Support restrictions
H How to configure the probe adapter
H How to connect to the system under test (SUT)
H How to apply power to and remove power from the probe adapter
The TMS 163 microprocessor support package disassembles data from systems
that are based on the Intel i960 Jx microprocessor. The support runs on a
compatible Tektronix logic analyzer equipped with a 102/136-channel module or
a 96-channel module.
Refer to information on basic operations to determine how many modules and
probes your logic analyzer needs to meet the minimum channel requirements for
the TMS 163 microprocessor support.
Table 1–1 shows which microprocessors, packages, and clock rates the TMS 163
product supports.

1–1
Getting Started
Information on basic operations also contains a general description of supports.
Logic Analyzer Software Compatibility
The label on the microprocessor support floppy disk states which version of logic
analyzer software the support is compatible with.
Logic Analyzer Configuration
To use the i960 Jx support, the Tektronix logic analyzer must be equipped with
either a 102/136-channel module, or a 96-channel module at a minimum. The
module must be equipped with enough probes to acquire channel and clock data
from signals in your i960 Jx-based system.
Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.
Requirements and Restrictions
You should review the general requirements and restrictions of microprocessor
supports in the information on basic operations as they pertain to your SUT.
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 i960 Jx support requirements
and restrictions.
System Clock Rate. The TMS 163 support can acquire data from the i960 Jx
microprocessor at speeds of up to 33 MHz for 960 JA/JF
960 JD; it has been tested to 33 MHz for 960 JF microprocessor.
Disabling the Instruction Cache, Data Cache, and Vector Cache. To disassemble
acquired data, you must disable the internal Instruction cache, the internal Data
cache. Disabling the caches makes all instruction prefetches visible on the bus so
they can be acquired and disassembled.
Vector caching has to be disabled so that microprocessor fetches the interrupt
vector entries from external RAM and not from internal RAM. This will reflect
the vector reads to external bus.

TMS 163 i960 Jx Microprocessor Support Instruction Manual
Configuring the Probe Adapter
If your system under test (SUT) has a +3 V i960 Jx microprocessor or you do not
want the SUT to provide power to the probe adapter when the probe adapter is in
an SUT with a +5 V microprocessor, you can use an alternate power source. If
you use an alternate power source, you need to place the Power Source jumper
on pins 1 and 2.
If your SUT has a +5 V i960 Jx microprocessor, and the probe adapter will be
powered from the SUT, you need to place the Power Source jumper on pins 2
and 3.

Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module.
Your SUT must also have a minimum amount of clear space surrounding the
microprocessor to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.

Getting Started
The channel and clock probes shown in this chapter are for a 102/136-channel
module. The probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microprocessor supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.
Probe Adapter with a
High-Density Probe
To connect the logic analyzer to an SUT using the PGA probe adapter and a
high-density probe, follow these steps:
1. Turn off power to your SUT. It is not necessary to turn off power to the logic
analyzer.
CAUTION. Static discharge can damage the microprocessor, the low-profile probe
adapter, the probes, or the module. To prevent static damage, handle all of the
above only in a static-free environment.
Always wear a grounding wrist strap or similar device while handling the
microprocessor and low-profile probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch the black foam on the
underside of the probe adapter to discharge stored static electricity from the
probe adapter.
3. Remove the microprocessor from the SUT.
4. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on the microprocessor.
1–4
CAUTION. Failure to correctly place the microprocessor into the probe adapter
might permanently damage the microprocessor once power is applied.
5. Place the microprocessor into the probe adapter as shown in Figure 1–2.

7. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on the SUT.
8. Place the probe adapter onto the SUT as shown in Figure 1–3.
NOTE. You might need to stack one or more replacement sockets between the SUT
and the probe adapter to provide sufficient vertical clearance from adjacent
components. However, keep in mind this might increase loading, which can
reduce the electrical performance of the probe adapter.

9. Connect the channel and clock probes to the high-density probe as shown in
Figure 1–4. Match the channel groups and numbers on the probe labels to the
corresponding pins on the high-density probe. Match the ground pins on the
probes to the corresponding pins on the probe adapter.
Since the data bus is multiplexed with the address bus, acquisition probes
D3:7-0, D2:7-0, D1:7-0, and D0:7-4, do not have to be connected. Even if
the probes are not connected, the Data channel group will still acquire data
through the address bus. Since data is being acquired, these probes are not
considered to be extra channels that you can use to connect to other signals in
your SUT.

4. Press down on the probe adapter to secure the clip on the microprocessor.
5. Continue with steps 9 and 10 from the previous procedure.
Without a Probe Adapter
You can use channel probes, clock probes, and leadsets with a commercial test
clip (or adapter) to make connections between the logic analyzer and your SUT.
To connect the probes to i960 Jx signals in the SUT using a test clip, follow these
steps:
1. Turn off power to your SUT. It is not necessary to turn off power to the logic
analyzer.
CAUTION. Static discharge can damage the microprocessor, the probes, or the
module. To prevent static damage, handle all of the above only in a static-free
environment.
Always wear a grounding wrist strap or similar device while handling the
microprocessor.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. If you are using a test clip, touch any of the
ground pins on the clip to discharge stored static electricity from it.
CAUTION. Failure to place the SUT on a horizontal surface before connecting the
test clip might permanently damage the pins on the microprocessor.
1–10
3. Place the SUT on a horizontal static-free surface.
4. Use Table 1–2 to connect the channel probes to i960 Jx signal pins on the test
clip or in the SUT.
Use leadsets to connect at least one ground lead from each channel probe and
the ground lead from each clock probe to ground pins on your test clip.
NOTE. Since the microprocessor multiplexes the Address and Data buses, the
D3:7-0, D2:7-0, D1:7-0 and D0:7-0 channel probes do not need to be connected.
Although they are not connected, they are not considered to be extra channels.
Do not use them to make connections to other signals in your SUT.

Applying and Removing Power
If your microprocessor system cannot supply power to the i960 Jx probe adapter
or your system has a +3 V i960 Jx microprocessor (probe adapters need +5 V),
you must use an alternate power source. A +5 V power supply is included with
this support product.
1–12
TMS 163 i960 Jx Microprocessor Support Instruction Manual
Getting Started
The alternate power supply provides +5 volts to the i960 Jx probe adapter. The
center connector of the power jack connects to Vcc.
To use the power supply, you need to position the Power Source jumper on pins 1
and 2.
To apply power to the i960 Jx probe adapter and SUT, follow these steps:
CAUTION. Failure to use the +5 V power supply provided by Tektronix might
permanently damage the probe adapter and i960 Jx microprocessor. Do not
mistake another power supply that looks similar for the +5 V power supply.
1. Connect the +5 V power supply to the jack on the probe adapter. Figure 1–8
shows the location of the jack on the adapter board.
CAUTION. Failure to apply power to the probe adapter before applying power to
your SUT might permanently damage the i960 Jx microprocessor and SUT.
2. Plug the power supply for the probe adapter into an electrical outlet.
3. Power on the SUT.
