TMS 165 i960RP Microprocessor Support Instruction Manual ix
Preface: Microprocessor Support Documentation
This instruction manual contains specific information about the TMS 165 i960RP
microprocessor support package and is part of a set of information on how to
operate this product on compatible Tektronix logic analyzers.
If you are familiar with operating microprocessor support packages on the logic
analyzer for which the TMS 165 i960RP support was purchased, you will
probably only need this instruction manual to set up and run the support.
If you are not familiar with operating microprocessor support packages, you will
need to supplement this instruction manual with information on basic operations
to set up and run the support.
Information on basic operations of microprocessor support packages is included
with each product. Each logic analyzer has basic information that describes how
to perform tasks common to support packages on that platform. This information
can be in the form of online help, an installation manual, or a user manual.
This manual provides detailed information on the following topics:
HConnecting the logic analyzer to the system under test
HSetting up the logic analyzer to acquire data from the system under test
HAcquiring and viewing disassembled data
HUsing the probe adapter
Manual Conventions
This manual uses the following conventions:
HThe term “disassembler” refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
HThe phrase “information on basic operations” refers to online help, an
installation manual, or a basic operations of microprocessor supports user
manual.
HThe term “XXX” or “P54C” used in field selections and file names must be
replaced with i960RP. This is the name of the microprocessor in field
selections and file names you must use to operate the i960RP support.
HThe term “SUT” (system under test) refers to the microprocessor-based
system from which data will be acquired.

Preface: Microprocessor Support Documentation

Getting Started
This chapter provides information on the following topics and tasks:
HA description of the TMS 165 microprocessor support package
HLogic analyzer software compatibility
HYour SUT (system under test) requirements
HSupport restrictions
HHow to connect to your SUT
Support Description
The TMS 165 microprocessor support package disassembles data from systems
that are based on the i960RP microprocessor. The support runs on a compatible
Tektronix logic analyzer equipped with a 102/136-channel module or a 96-chan-
nel 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 165 microprocessor support.
The TMS 165 supports the i960RP microprocessor in a 352-pin BGA package.
A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Mechanical Parts chapter.
A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Parts chapter.
To use this support efficiently, you need to have the items listed in the informa-
tion on basic operations as well as the i960RP Microprocessor User’s Manual,
Intel, February 1996, Intel order number: 272736-001
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.

Getting Started
1–2 TMS 165 i960RP Microprocessor Support Instruction Manual
Logic Analyzer Configuration
To use the i960RP 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 i960RP-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 i960RP support requirements
and restrictions.
System Clock Rate. The TMS 165 support can acquire data from the i960RP
microprocessor at speeds of up to 33 MHz1.
Hardware Reset. If a hardware reset occurs in your i960RP system during an
acquisition, the disassembler might acquire an invalid sample.
Cache Invalidation. Correct disassembly is not guaranteed for microprocessor
systems that run cache invalidations concurrent with burst cycles. Data for these
cycles will not be disassembled and will be labeled as Cache Invalidation cycles.
Disabling the Instruction Cache. To disassemble acquired data, you must disable
the internal instruction cache. Disabling the instruction cache makes all
instruction prefetches visible on the bus so that they can be acquired and
disassembled.
Disabling the Data Cache. To disassemble acquired data, you must disable the
internal data cache. Disabling the data cache makes all data prefetches visible on
the bus so that they can be acquired and disassembled.
1Specification at time of printing. Contact your Tektronix sales representativefor
current information on the fastest devices supported.

Getting Started
TMS 165 i960RP Microprocessor Support Instruction Manual 1–3
Dynamic Bus Sizing. When the Bus Size Control signals (BS16# or BS8#) are
asserted, the i960RP microprocessor allows the bus width to be changed to
handle extra cycles (when more than one cycle is required for a transaction). The
disassembler does not support changing the bus size for extra cycles. To keep the
disassembler synchronized, you can use the mark cycles function as described in
the Operating Basics chapter.
Automatic dequeueing. Automatic dequeueing may not be performed in all
circumstances. When a branch takes place the automatic dequeueing may or may
not take place depending on word alignment of the target of the branch. For more
information on automatic dequeueing and word alignment refer to section 4.3.2
in the i960RP Microprocessor User’s Manual, Intel, February 1996.
PCI Functionality. PCI functionality is not supported on the i960RP support.
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 to accommodate the
probe adapter. Refer to the Specifications chapter in this manual for the required
clearances.
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.
To connect the logic analyzer to a SUT using the elastomer and the probe
adapter, 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 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 probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer.
With a Probe Adapter and
Elastomer

Getting Started
1–4 TMS 165 i960RP Microprocessor Support Instruction Manual
3. Place the elastomer over the pad array on your SUT. The elastomer is keyed
by one of the three holes being larger then the other two.
4. Place the probe adapter over the elastomer being careful to orient the larger
hole in the probe adapter over the larger flange of the elastomer.
CAUTION. Failure to correctly place the elastomer may result in damage to the
probe adapter, the elastomer, and your SUT.
One of the holes on the Probe Adapter is larger then the other two. The larger
hole is a key for the large flange on the elastomer.
5. Fasten the probe adapter to the SUT using three screws, six flat washers, and
three hex nuts. Refer to Figure 1–1.
6. Tighten the screws. The elastomer needs to be compressed at the rate of 3 lb.
per linear inch. Tighten the screws at a torque rating of 3 in. lbs, minimum,
and 8 in. lbs., maximum torque.
