TMS 545 PPC 7400 Microprocessor Support Instruction Manual
Preface
This instruction manual contains specific information about the TMS 545 PPC
7400 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 545 PPC 7400 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 includes 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:
H Connecting the logic analyzer to the system under test
Manual Conventions
H Setting up the logic analyzer to acquire data from the system under test
H Acquiring and viewing disassembled data
This manual uses the following conventions:
H The term “disassembler” refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
H The phrase “information on basic operations” refers to online help, an
installation manual, or a user manual covering the basic operations of
microprocessor support.
H In the information on basic operations, the term “XXX” or “P54C” appearing
in field selections and file names must be replaced with PPC 7400. This term
is the name of the microprocessor in field selections and file names you must
use to operate the PPC 7400 support.
H The term “SUT” (system under test) refers to the microprocessor-based
system from which data will be acquired.

Preface
H The term “logic analyzer” refers to the Tektronix logic analyzer for which
this product was purchased.
H The term “module” refers to a 128-channel or a 96-channel module.
H The term “HI module” refers to the module in the higher-numbered slot and
the term “LO module” refers to the module in the lower-numbered slot.
H PPC 7400 refers to all supported variations of the PPC750 or PPC740
microprocessors unless otherwise noted.
H An underscore (_) following a signal name indicates an active low signal.
Logic Analyzer Documentation
A description of other documentation available for each type of Tektronix logic
analyzer is located in the user manual of the corresponding module. The manual
set provides the information necessary to install, operate, maintain, and service
the logic analyzer and its associated products.

Getting Started
Getting Started
This chapter contains information on the TMS 545 microprocessor support, and
information on connecting your logic analyzer to your system under test.
Support Package Description
The TMS 545 microprocessor support package displays disassembled data from
systems based on the PowerPC PPC 7400 microprocessor.
The TMS 545 Support is comprised of the following:
H TMS 545 Support SW Disk
H TMS 545 Support Instruction Manual
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 545 microprocessor support.
To use this support efficiently, you need the items listed in the information on
basic operations as well as the MPC 750 RISC Microprocessor User’s Manual,
1997 and the PowerPC Max Microprocessor Implementation Definition Book 1V
Version 2.0, Motorola, 1998.
Options
The following options are available when ordering the TMS 545 Support:
H Option 21 Add 4 P6434 Probes
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
For use with a TLA 700 Series the TMS 545 support requires a minimum of
one 136-channel module.

Getting Started
Requirements and Restrictions
Review electrical specifications in the Specifications chapter in this manual as
they pertain to your system under test, as well as the following descriptions of
other PPC 7400 support requirements and restrictions.
Hardware Reset. If a hardware reset occurs in your PPC 7400 system during an
acquisition, the application disassembler might acquire an invalid sample.
System Clock Rate. The PPC 7400 microprocessor support can acquire data from
the PPC 7400 microprocessor operating at speeds of up to 133 MHz. The PPC
7400 microprocessor support has been tested to 100 MHz.
Channel Groups. Channel groups required for clocking and disassembly are the
Address Group, Hi_Data Group, Lo_Data Group, Control Group, Transfer
Group, and Tsiz Group.
Timing Display Format
Channel group not required for clocking and disassembly is the Misc Group.
Disabling the Instruction Cache. To display disassemble acquired data, you must
disable the internal instruction cache. Disabling the cache makes all instruction
prefetches visible on the bus so that they can be acquired and displayed
disassembled.
Disabling the Data Cache. To display acquired data, you must disable the data
cache. Disabling the data cache makes visible on the bus all of the loads and
stores to memory, including data reads and writes, so the software can acquire
and display them.
A Timing Display Format file is provided. It sets up the display to show the
following waveforms:
CLK, BR_, Address, TS_, ABB_, BG_, AACK_, ARTRY_, TBST_,
Hi_Data, Lo_Data, TA_, DBB_, DBG_, TEA_, DTI[1]/DRTRY_, Control,
Tsiz, Transfer.
NOTE. Address, Hi_Data, Lo_Data, Control, Tsiz, and Transfer are displayed in
bus form.
1–2
The method of selecting or restoring the Timing Display Format file is different
for each platform, and will be ignored in this document.
TMS 545 PPC 7400 Microprocessor Support Instruction Manual
Functionality Not Supported
Interrupt Signals. All of the interrupt signals are not acquired by the TMS 545
support software. The interrupts that are acquired can be identified by the
TMS 545 support software by looking at the address that is displayed for the
interrupt service.
Microprocessor. The PPC 7400 acquires all the address and data cycles on the bus
and does not differentiate between potential master and alternate master.
L2 cache. L2 cache transactions are not supported for the PPC 7400.
Extra Acquisition Channels. Extra Acquisition Channels are not available on the
TLA 700.
Alternate Bus Master. Alternate bus master transactions are not processed in the
disassembly.
Getting Started
Address Pipelining. If address pipelining continues for several sequences (those
longer than approximately 1 K), performance might be degraded when you scroll
data by entering a sequence number in the cursor field.
If address pipelining continues for additional sequences of 1 K or greater,
erroneous address and data association might occur. You can use the Mark Cycles
function to correct the interpretation of erroneous address and data association.
See Marking Cycles on page 2–16 for information on how to correct improper
address and data association.

Channel Assignments
Channel assignments shown in Table 1–1 through Table 1–8 use the following
conventions:
H All signals are required by the support unless indicated otherwise.
H Channels are shown starting with the most significant bit (MSB) descending
to the least significant bit (LSB).
H Channel group assignments are for all modules unless otherwise noted.
