TMS 109A Socket 7 Microprocessor Support ix
Preface
This instruction manual contains specific information about the TMS 109ASock-
et 7 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 109A Socket 7 support was purchased, you will 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.
NOTE. The disassembly software is optimized to decode instruction streams and
bus activities from Intel microprocessors and AMD-K6-2 therefore, the disassem-
bler may not support unique characteristics of other manufacturers. However,
you can reliably conduct timing analysis of nonIntel Socket 7 processors. Consult
your Tektronix field office for future enhancements.
Manual Conventions
This manual uses the following conventions:
HThe term “disassembler” refers to the software that decodes bus cycles into
instruction mnemonics and cycle types.
HA pound sign (#) following a signal name indicates an active low signal.
HThe phrase “information on basic operations” refers to your online help.

TMS 109A Socket 7 Microprocessor Support 1–1
Getting Started
This chapter contains information on the TMS 109A Socket 7 microprocessor
support package:
HHow to configure the probe adapter
HHow to connect to the system under test
HHow to apply power to and remove power from the probe adapter
Support Package Description
The TMS 109A Socket 7 microprocessor support package disassembles data
from systems that are based on the Intel Pentium, low-power embedded Pentium
with MMX technology, AMD-K6-2 and Socket 7 microprocessor devices. The
support runs on a compatible Tektronix logic analyzer equipped with a 136-chan-
nel module.
A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Parts List chapter.
To use this support efficiently, you must have the items listed in the information
on basic operations (in the online help) and the following items:
HPentium Processors Family Developer’s Manual, Intel 1997(p/n to be
updated)
HAMD-K6-2 Processor, Data Sheet, AMD, 1999
Information on basic operations is also in your online help.
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 TMS 109A Socket 7 support package, the Tektronix logic analyzer
must be equipped with a 136-channel module at a minimum.

Getting Started
1–2 TMS 109A Socket 7 Microprocessor Support
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 109A Socket 7 microprocessor support.
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 system
under test.
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 Socket 7 support requirements
and restrictions.
System Clock Rate. The TMS 109A Socket 7 support can acquire data from the
Socket 7 microprocessors at bus speeds of up to 100 MHz; the tested clock speed
is 100 MHz. This specification is valid at the time this manual was printed.
Contact your Tektronix sales representative for current information on the fastest
devices supported.
System Under Test Power. Whenever the system under test is powered off, be sure
to remove power from the probe adapter. Refer to Applying and Removing Power
on page 1–13 for information on how to remove power from the probe adapter.
Disabling the Instruction Cache. To disassemble acquired data, you must disable
the internal instruction cache. Disabling the cache makes all instruction
prefetches visible on the bus so they can be acquired and disassembled.
Cache Invalidation Cycles. Cache Invalidation addresses are not acquired.
Bus Hold Cycles. Bus Hold cycles are not acquired while the RESET signal is
active.
AHOLD Signal. If the AHOLD signal is active (high) during a Writeback cycle (a
four cycle Burst Write), the acquired address is undefined.
Burst Cycles. The Socket 7 microprocessor expects the memory system to
increment addresses during a Burst cycle. When viewing disassembled data, the
disassembler synthesizes the addresses. When viewing state data, the addresses
appear to be identical.

Probe Mode Cycles. Probe Mode cycles are not identified.
Directory Table and Descriptor Table Reads and Writes. These reads and writes are
not disassembled.
Bus Anomalies. Some combinations of instructions and operating modes of the
microprocessor can cause additional cycles to be fetched. This behavior is
unpredictable, not documented, and can cause the disassembler to operate
incorrectly with fetched cycles. This is most likely to occur during Floating Point
operations.
AMD-K6-2 processor has a out-of-order fetch mechanism. For fetches, AMD
always loads 32 bytes, starting from the most significant octabyte (octet) in the
block. For example these addresses 00, 08, 10, and18 would be fetched in this
order 18, 10, 08, and 00. Regardless of what the critical word is or if the cache is
enabled. For the disassembler to work properly it needs these 32 byte fetch
blocks or the disassembly will be incorrect.
Nonintrusive Acquisition. The Socket 7 microprocessor support will not intercept,
modify, or present signals back to the system under test.
Functionality Not Supported
Reads/Writes. The TMS 109A Socket 7 support package does not interpret
directory or descriptor tables for reads/writes. When long jumps and calls are
executed you may need to supply a code-segment size (see page 2–18), and the
first opcode byte using the Mark Opcode function (see page 2–25).

Configuring the Probe Adapter
There are five jumpers on the probe adapter. Table 1–1 lists the jumper positions
and functions.
Table 1–1: Jumper positions and function
Probe adapter Position Function
J240
MFG_TEST 1–2
OPEN
When the processor extends the clock speed to below 40 MHz, the jumpered pins 1-2
turn the phased lock loop into a buffer that disables the phased lock loop signal.
Default, phased look loop signal enabled
J250
CLK 1–2
2–3
Extends the Socket 7 microprocessor system speed between 40–150 MHz
Extends the Socket 7 microprocessor system speed between 20–75 MHz
J900
Proc Sel 1–2
2–3
Supports microprocessors that do not have the D/P# pin.
Supports microprocessors that have the D/P# pin.
J910
D/P# 1–2
OPEN
Acquires the D/P# signal from pin AE35 of the socket being probed.
Acquires the D/P# signal from an external source. If this jumper is left open, you must
route the D/P# signal to pin 1 of this jumper from an external source. This allows you to
probe your system from the Dual socket as long as the D/P# signal is accessible on the
system board. Ensure that the jumper J900 is in position 2–3 before routing the D/P#
signal to pin 1 of J910.
J920
Tracking 1–2
2–3
Enables tracking of burst and pipelined cycles while BOFF# and HLDA are asserted
Disables tracking of burst and pipelined cycles while BOFF# and HLDA are asserted.
This setting can be used if an external master’s signal timing is different from that of the
P54C.

Enable Address Synthesis (A(2:0) are derived from BE(7:0)#)
DisableAddressSynthesis(A(2:0)=0)
To acquire data at frequencies below 40 MHz on the probe adapter, short the two
pins on J240. This disables the phased lock loop signal to all clocked compo-
nents. Figure 1–1 shows the location of J240 on the probe adapter.
