Introduction
What's In This Manual
This manual describes the installation and operation of your Catalyst
PCI Bus Analyzer / Exerciser. Examples of some typical applications
are included.
The terms TA660 and PCI analyzer thereafter are used for referring to
both PCI and CompactPCI analyzers (see Appendix B).
Overview
Your TA660 PCI Bus Analyzer is a powerful and versatile analysis
tool that will permit you to debug and characterize PCI designs
operating on any PCI system architecture . To perform analysis you
simply install the analyzer card in a PCI slot in the target machine and
connect it to the host computers Bi-directional parallel port using the
25 pin parallel cable, provided with your analyzer. A typical setup
may include a Host and a Target systems interconnected via the
parallel port with the analyzer card installed in the Target Machine
and a Windows based host running the analysis software.
If your target machine operates under Windows it may also act as the
host. In this case, the analyzer card and the analysis software reside in
the same machine and require you to connect the analyzer card to the
Host high-speed parallel port using the 25 pin parallel cable. See
Figure 1.
Operating the analyzer in this mode, however, may impact
Performance Analysis measurement accuracy since the
analyzer software runs in the same system space as the
application software. For a precise Performance Analysis it
is recommended that you use a separate Host system.

TA660 User's Manual Catalyst Enterprises, Inc
Figure 1 Target and Host Operating in the Same Machine
Optional Auxiliary PCI connector
The PCI Bus Analyzer Card incorporates a PCI connector on top
which extends the system PCI bus and allows other PCI cards to be
plugged into the analyzer for development or production testing. This
feature allows the analyzer to monitor the same point-to-point signals
such as REQ# & GNT# on the card under test without requiring any
external connections. In this mode, both the analyzer and the card
under test require only one PCI slot. Special design methodology has
been incorporated to minimize any reflections, delay or cross-talk.
This feature only exists on the TA660A PCI analyzer and not on the
Compact PCI version.
Figure 2 illustrates such a test setup. An On-Off switch on the
analyzer card enables and disables the power and signal connections
between the system and the card under test allowing rapid cycling of
the test cards without shutting off the system power.

Status LED Function Description
SYS When green Indicates if the system voltages are within 5%
of their value. If any of +5V, +3.3V, +12V drop more than
5% the SYS LED turns red. SYS LED also comes up red as
a test on power on and then if the voltages are okay it turns
green once the software is executed. To enable voltages for
sensing see on page 15.
DUT Indicates that the voltage to the DUT is on. In this case the
user may not remove or insert any card in to the top
connector of the TA660.
CONF Indicates that TA660 has been recognized and configured
by the software, therefore the parallel port link is working.
TRIG Indicates that the analyzer has met the trigger condition and
is awaiting for the defined post-trigger data to be captured.

Installing Your Analyzer
Hardware Installation
1. Make sure that the Target Machine is powered down.
2. Remove the case from your machine in accordance with the
instructions supplied for it.
3. Install the Analyzer card in any available PCI slot and secure the
mounting bracket to the chassis with the mounting screw.
Warning: Make sure to take precautions to avoid static electricity
discharge damage to the Analyzer Card by using a
grounding strap or touching a grounded metal surface just
prior to handling the analyzer card. Avoid touching any
components and handle card by the edges only.
4. Interconnect the Analyzer DB-25 connector to the Host system Bi-
directional parallel port using the provided DB-25 pin cable.
Host and Target Same The Analyzer may be used in a configuration such that the
Host and Target are the same machine.
Bi-Directional Port The Analyzer requires that The Host parallel port support
Bi-directional data transfers. See LPT Port Setting for
verifying that your parallel port supports and/or is set to a
Bi-directional mode. If the parallel port on your Host
system does not support Bi-directional data transfers you
must then install the parallel port card supplied with your
analyzer in a spare ISA slot and connect to it.
Port Configuration The parallel port card supplied with your analyzer is pre
configured for LPT2 (H278). If the Host system is using this
address for its printer port, you must then change the jumper
configuration on the ISA parallel card to H378 (LPT1).

TA660 Overview
The TA660 PCI Bus Analyzer/Exerciser has a convenient, easy to use
Easy Mode that allows you to perform 95% of your PCI bus data
capture & trigger without any programming.
An Advanced Mode offers you a powerful programming capability
for complex triggering.
The TA660 incorporates an Exerciser that generates bus transactions
to exercise the bus as a master or target while allowing you to monitor
and capture the resulting performance.
A Timing Analyzer capability is also included that allows the user to
capture bus timing violations.
Additionally, the TA660 includes Performance Analysis for realtime and statistical measurement as well as comprehensive Device
Compliance Test capabilities.
TA660 Configurations
The TA660 may be operated in one of 3 configurations, each offering
a convenient Easy Mode which requires no programming:
State Analyzer Only
To perform a variety of data capture and trigger and bus analysis.
State & Timing Analyzer
To perform timing analysis for possible violation and to characterize
Setup & Hold limits on all or selected signals.
State Analyzer & Exerciser
To perform Device compliance testing, characterize a PCI device by
emulating various bus cycles & terminations, injecting errors and
generating traffics to measure the PCI bus response. The exerciser
may be used as a bus master to test and debug new designs.
The operating configuration is selectable on the Main Menu Bar.
7
TA660 User's Manual Catalyst Enterprises, Inc
Performance Analysis
The TA660 provides continuous Real-Time performance analysis that
operates with Pre-defined or User-defined analysis files. On-board
dual ported FIFOs interface between the counters and the host system
for transferring the measured data in real-time without ever having to
stop the counters. This feature provides a very complete and accurate
event count of up to 533 MB/Sec. An implementation of twelve
counters with up to 32 bits allows a virtually unlimited count of
events.
TA660A includes 12 counters, 8 of which may be programmed to
monitor the primary bus activities and the other 4 may used for
connection to point-to-point signals or the secondary bus.
Your TA660 includes complete setups to measure the most typical
parameters as well as giving you the ability to create your own setup.
Real time Performance Analysis allows you to count actual data
transfers for any agent or agents matching user specified address,
measure and report bus utilization efficiencies, throughput, latencies
and retries, on-the-fly.
You may use real time Performance Analysis simultaneously with the
exerciser to generate traffic on the bus and measure performance of
the target.
Performance Analysis results are presented in a Twelve-color display
that you may customize with your own color preferences and may be
recorded in graphical format for later review or demonstration.
Measurement intervals are selectable from 500 µsec to 10 minutes.
Statistical Analysis
Statistical Analysis is implemented by capturing data in memory and
then performing software post processing.
Statistical Analysis measures and reports on Min, Max and Average
occurrences for several different parameters such as Latencies, Retry,
Data Transfers, Command Utilization, Bus Utilization and various
Target Terminations.
The PCI Analyzer (Allowing the Master card to be plugged into
the expansion slot on top) can also measure latencies from request
to the 1st data transfer including all of the retries in between.
The data capture & trigger for post processing may be initiated per
user defined events on the bus, therefore yielding a very repetitive and
consistent result.
8
TA660 User's Manual Catalyst Enterprises, Inc
The parameters measured may be selected for graphical display on the
screen and may be saved as graphical or list files for later review.
In the exerciser mode the TA660 can initiate data transfer to a target
while the trace statistics measures the latency response of the target.
Special Capabilities
Several other features are included in the TA660 such as Protocol
Errors, Mnemonics, Device Compliance Testing. Please refer to the
appropriate sections for each of these features.

Data Capture Options
Memory Display You may limit the captured data display to a specific
number of samples by checking Partial Memory and
entering the number of Samples to be captured or, you may
check entire memory to allow the capture for the entire
memory.
Pre-Trigger Pre-Trigger is set by default at 50% which defines the
percentage of data to be captured before and after the
triggering event. You may change this percentage by
dragging the slider to the desired value.
Pre-Trigger Data: The capture of the specified percentage of the data prior to
the triggering event cannot be guaranteed and may in some
cases be 0. This can occur in cases where the triggering
event occurs before the required number pre-trigger event
data can be stored. In these cases the data display will show
fewer than the specified data points prior to the triggering
event. For more detail see Set Trigger on page 69.
Manual Trigger Select this option when you wish to manually interrupt the
data capture based on some external event. With this option
selected, data will be continually captured to memory and
overwritten as required until you stop the data capture.
Continuous Mode Continually captures data for the number of times specified.
A separate data file is generated each time that a capture is
performed.
Exclude Cycles To simplify the captured data display you may check the
options to exclude, Idles, Wait States and Retries.
