Preface
This instruction manual contains specific information about the
TMS 531 PPC 403GX 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 531 PPC 403GX 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:
Manual Conventions
H Connecting the logic analyzer to the system under test
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 your online help.
H The term “logic analyzer” refers to the Tektronix logic analyzer for which
this product was purchased.

Getting Started
Getting Started
This chapter contains information on the TMS 531 PPC 403GX microprocessor
support package.
Support Package Description
The TMS 531 PPC 403GX microprocessor support package displays disassembled data from systems based on the PPC 403GX IBM microprocessor. The
support runs on a compatible Tektronix logic analyzer.
To use this support efficiently, refer to information on basic operations and the
following documents:
H PowerPC 403GA Data Sheet, IBM Microelectronics, 9–97
H PowerPC 403GC Data Sheet, IBM Microelectronics, 9–97
H PowerPC 403GCX Data Sheet, IBM Microelectronics, 3–98
H PowerPC 403GA User Manual, IBM Microelectronics, 3–95
H PowerPC 403GC User Manual, IBM Microelectronics, 3–95
H PowerPC 403GCX User Manual, IBM Microelectronics, 5–98
The following is a list of microprocessors the TMS 531 PPC 403GX support can
acquire and display as disassembled data:
PPC 403GA
PPC 403GC
PPC 403GCX
Logic Analyzer Software Compatibility
The version of logic analyzer software that is compatible with this support is
listed on the label of the floppy disk.
Logic Analyzer Configuration
The TMS 531 PPC 403GX support requires a minimum of a 102-channel
module.

Getting Started
Requirements and Restrictions
Review the electrical specifications in the Specifications chapter in this manual
as they pertain to your system under test, and the following descriptions of other
PPC 403GX support requirements and restrictions.
Hardware Reset. If a hardware reset occurs in your PPC 403GX system during an
acquisition, the application disassembler might acquire an invalid sample.
System Clock Rate. The PPC 403GX microprocessor support can acquire data
from the PPC 403GX microprocessor operating at speeds of up to 40 MHz. The
PPC 403GX microprocessor support has been tested to the 33 MHz clock rates.
The operating clock rate specifications were measured at the time of printing.
Contact your Tektronix sales representative for current information on the fastest
devices supported.
Disabling the Instruction Cache. To display disassembled 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 all loads and stores to memory on
the bus, including data reads and writes, so the software can acquire and display
them.
Nonintrusive Acquisition. The PPC 403GX microprocessor will not intercept,
modify, or present signals back to the system under test.
Support Software. The PPC 403GX Support Software is not tested for DRAM
Data Read on CAS mode or EDO (2-1-1-1) mode.
MMU Address Translation. The MMU address translation must be turned off for
proper disassembly.
1–2
TMS 531 PPC 403GX Microprocessor Support
Functionality Not Supported
Real Time Debug. You must enable the PPC 403GX microprocessor Real Time
Debug trace signals for the TMS 531 PPC 403GX support to disassemble data.
When enabled the debug trace signals generate the Program Status and Bus
Status signals. This also makes available qualifiers for the CSM and Instruction/
Data signals for disassembly.
Bus Status Mode must be enabled in the IOCR (Input/output configuration
register). To enable the Bus Status Mode, the ReaL-Time Debug Mode bits
(IOCR [RDM]) must be set to 01 in IOCR register.
NonDRAM. NonDRAM cycles may not be acquired correctly when Data Read on
CAS mode or EDO (Other) mode are selected.
Byte Enable. You can choose to configure Byte Enable signals as either Write
Enable or Byte Enable for both reads and writes. If the Byte Enable signals are
not configured for both reads and writes, the byte invalidation for reads and
writes is not executed.
Getting Started
Interrupt Signals. The interrupt signals are not acquired by the
TMS 531 PPC 403GX support software; however, the interrupt signals are
identified when looking at the address displayed for the interrupt service.
Extra Acquisition Channels. Extra Acquisition Channels are not available.
Show Cycle. The show cycle signals are not acquired by the
TMS 531 PPC 403GX support software.
External Master Cycles. Asynchronous External Master cycles are not acquired.
Connecting the Logic Analyzer to a System Under Test
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 system
under test.
To connect the probes to PPC 403GX signals in the system under test using a test
clip, follow these steps:
1. Power down your system under test. It is not necessary to power down the
logic analyzer.
TMS 531 PPC 403GX Microprocessor Support
1–3
Getting Started
CAUTION. To prevent static damage, handle these components only in a staticfree environment. Static discharge can damage the microprocessor, the probes,
and the logic analyzer module.
Always wear a grounding wrist strap, heel 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 the test clip.
3. Place the system under test on a horizontal, static-free surface.
4. Refer to Tables 1–1 through 1–6, and connect the channel probes to
PPC 403GX signal pins on the test clip or in the system under test.
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.
Channel Assignments
Channel assignments listed in Tables 1–1 through 1–6 use the following
conventions:
H All signals are required by the support unless indicated otherwise.
H Channels are listed 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.
H An tilde symbol (
~) following the signal name indicates an active low signal.
Table 1–1 lists the probe section and channel assignments for the Address group
and the microprocessor signal for each channel connect. By default, this channel
group is displayed in hexadecimal.
