Getting Started

Getting Started

This section contains information on the TMS546 MPC7410 microprocessor
support, and information on connecting your logic analyzer to your target system.

Support Package Description

The TMS546 microprocessor support package displays disassembled data from
systems based on MPC740/745/750/755/7400/7410/7441/7445/7450/7451/7455,
PPC750FX and PPC750CX PowerPC microprocessors. The TMS546 micropro­cessor support package will install four supports.

H MPC7410 will support MPC740, MPC745, MPC750, MPC755, MPC7400,

MPC7441, MPC7445, MPC7410, MPC7450, MPC7451, MPC7455, and

PPC750CX, and PPC750FX PowerPCs.

H MPC7450 will support MPC7441, MPC7450, MPC7451, and MPC7455

PowerPCs.

H MPC7410_ALT will support alternate layout and dual processor disassembly

for MPC7400, MPC7410, MPC7441, MPC7445, MPC7450, MPC7451, and

MPC7455 PowerPCs.

H MPC7410_QD will support alternate layout and quad processor disassembly

for MPC7400, MPC7410, MPC7441, MPC7445, MPC7450, MPC7451, and

MPC7455 PowerPCs.

Contact your Tektronix sales representatives for a current list of supported
MPC7XX/74XX processors.

The TMS546 support package has Internal Trace Reconstruction (ITR) feature
for all processors, both in 60X and MPX bus modes.

TMS546 Compatibility. The TMS546 support package channel assignment is
compatible with the earlier Mictor pin assignment for TMS541 PPC7X0 and
TMS545 PPC7400 processor supports. If you have an
MPC7441/7445/7450/7451/7455 PowerPC board with a TMS541 or TMS545
channel assignment, you get correct disassembly (except for control symbol
tables) by loading MPC7410 support and selecting the MPC7450 processor to
disassemble.

Getting Started

NOTE. Refer to TMS541 and TMS545 Microprocessor Support Instruction
Manuals if your MPC7450 board has TMS541 and TMS545 channel assign­ments.

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 TMS546 microprocessor support.

To use this support efficiently, you need the items listed in the information on
basic operations in your logic analyzer online help and the following user
manuals.

Requirements and Restrictions

Review electrical specifications in the Specifications section in this manual as
they pertain to your target system, as well as the following descriptions of other
TMS546 MPC7410 support requirements and restrictions.

If the board has the recommended TMS546 MPC7410 support channel assign­ment, then load MPC7410 support to disassemble the
MPC740/745/750/755/7400/7441/7445/7410/7450/7451/7455/PPC750CX/
PPC750FX processors.

If the board has the recommended TMS546 MPC7450 support channel assign­ment, then load MPC7450 support to disassemble the
MPC7450/7451/7455/7441/7445 processors.

If the board has recommended TMS546 MPC7410_ALT support channel
assignment, then load the MPC7410_ALT support to disassemble the
MPC7441/7445/7450/7451/7455 processors.

If the board has recommended TMS546 MPC7410_QD support channel
assignment, then load the MPC7410_QD support to disassemble the
MPC7441/7445/7450/7451/7455 processors.

Hardware Reset. If a hardware reset occurs in your TMS546 MPC7410 system
during an acquisition, the application disassembler might acquire an invalid
sample.

System Clock Rate(SYSCLK). The TMS546 MPC7410 microprocessor support can
acquire data from the TMS546 MPC7410 microprocessor operating at speeds of
upto 166 MHz

1

. The TMS546 MPC7410 microprocessor support has been tested

to 100 MHz.

Address Pipeline. The TMS546 support package is designed to support upto
16-level address pipelining. While acquiring data from systems having pipelin­ing, the acquisition may have data tenures without any corresponding address
tenures at the beginning of the acquisition. The disassembler, by default, starts
associating the first acquired data tenure with the first acquired address tenure.
This may cause wrong disassembly. You have to associate the first acquired

1

Specification at time of printing. Contact your Tektronix sales representative for
current information on the fastest devices supported.

TMS546 MPC7XX/MPC74XX Microprocessor Software Support

Getting Started

address tenure with the correct data tenure. This is done using “Invalid data”
marking option. You must mark all the data tenures without any corresponding
address as “Invalid data”. Once you associate a address tenure with the correct
data tenure, the disassembly adjusts itself for the change in the pipeline depth.

Setup and Hold Time Adjustments. You cannot change the setup and hold time for
any signal group.

HID0[IFTT] Bit Setting for TMS546 Support. When using TMS546 support for
MPC7400 and MPC7410 PowerPC the HID0[IFTT] must be set to 1 for a perfect
read/fetch indication. In this case, the disassembly uses TT signals for labeling
the cycles as Read or Fetch. If you do not set this bit, the disassembly uses
heuristic method to decide between Read and Fetch cycles.

Nonintrusive Acquisition. Acquiring microprocessor bus cycles is nonintrusive to
the target system. That is, the TMS546 MPC7410 does not intercept, modify, or
present signals back to the target system.

Channel Groups. Channel groups required for clocking and disassembly for
TMS546 MPC7410 microprocessor support are as follows:

MPC7410:

Address Group, High_Data Group, Low_Data Group, Control Group, Transfer
Group, T_Size Group, DTI Group and Misc Group.

MPC7450:

MSB_Addr Group, Address Group, High_Data Group, Low_Data Group,
Transfer Group, T_Size Group, Control Group, DTI Group and Misc Group.

MPC7410_ALT:

Address Group, High_Data Group, Low_Data Group, TraceAddr Group,

Connecting the Logic Analyzer to a Target System

You can use the channel probes, clock probes, and leadsets with a commercial
test clip (or adapter) to make the connections between the logic analyzer and
your target system.

To connect the probes to TMS546 MPC7410 signals in the target system using a
test clip, follow the steps:

1. Power off your target system. It is not necessary to power off the logic

analyzer.

CAUTION. To prevent static damage, handle the microprocessor, probes, and the
logic analyzer module in a static-free environment. Static discharge can damage
these components.

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 electricity from the test clip.

CAUTION. To prevent permanent damage to the pins on the microprocessor, place
the target system on a horizontal surface before connecting the test clip.

3. Place the target system on a horizontal, static-free surface.

4. Use Tables 3--13 through 3--52 starting on page 3--15 to connect the channel

probes to TMS546 MPC7410 signal pins on the test clip or in the target

system.

5. Use leadsets to connect at least one ground lead from each channel and the

ground lead from each clock probe to the ground pins on your test clip.
