Getting Started
Getting Started
This section contains information on the TMS822 UTOPIA2 bus support, and
information on connecting your logic analyzer to your target system.
Support Package Description
The TMS822 bus support package displays disassembled data from systems
based on Utopia Level 2 bus in the Transmit or Receive mode.
The highlights of Utopia Level 2 specification are as follows:
H Allows an 8-bit wide data path, using an octet-level handshake, operating up
to 25 MHz, with a single PHY device.
H Allows an 8-bit wide data path, using a cell-level handshake, operating up to
25 MHz with a single PHY device.
H Defines a 33 MHz data path interface operation, intended to simplify PCI
Bus ATM layer designs. This clock rate is used both with 8 and 16-bit wide
data paths. The 8-bit and 16-bit wide data path cell formats conform to the
specifications described in the Level 1 document.
H Defines a 50 MHz data path interface operation, intended for a 16-bit
interface at line rates of 622 Mbps.
H Defines the ‘physical’ operation of up to n PHY devices for the Multi-PHY
(MPHY) operation for the:
H n ≤ 8 at ATM layers intended for 155 Mbps;
H n ≤ 4 at ATM layers intended for 622 Mbps
with virtual space set up for n ≤ 31 PHY ports.
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 TMS822 support.
Since UTOPIA2 is backward compatible, the TMS822 support package can be
used to acquire cycles from UTOPIA Level 1 system also.
The highlights of Utopia Level 1 specifications are as follows:
H UTOPIA Level 1 defines the interface between the Physical (PHY) and
upper layer modules such as the ATM Layer.

Logic Analyzer Software Compatibility
The label on the bus support floppy disk states which version of logic analyzer
software this support is compatible with.
Logic Analyzer Configuration
The TMS822 support allows a choice of required minimum module configurations.
The Utopia Level 2 support package is divided into two support packages:
H UTOPIA2RX: UTOPIA2RX requires at least one 34 channel module to
acquire data from the receive interface.
H UTOPIA2TX: UTOPIA2TX requires at least one 34 channel module to
acquire data from the transmit interface.
1--2 TMS822 UTOPIA1/UTOPIA2 Software Support
To monitor both interfaces simultaneously (if both interfaces have a common
clock), the support requires two 34 channel modules. You must load the Transmit
support package in one of the 34 channel modules and the Receive support
package in the other. By double probing the common clock, the support acquires
the Transmit and Receive data information coming on the Utopia interface
simultaneously.
To use both supports (Transmit Interface and Receive Interface) at the same time,
the support requires two modules. To use only one support at a time, you must
select the correct module and specify the support.
Requirements and Restrictions
Review the electrical specifications in the Specifications section in this manual as
they pertain to your target system, as well as the following descriptions of other
TMS822 UTOPIA2 support requirements and restrictions.
Hardware Reset. If a hardware reset occurs in your TMS822 UTOPIA2 system
during an acquisition, the application disassembler might acquire an invalid
sample.
Getting Started
Clock Rate. The TMS822 UTOPIA2 bus support can acquire data from the
TMS822 UTOPIA2 bus operating at speeds of up to 50 MHz
1
. The TMS822
UTOPIA2 bus support has been tested to 16.7 MHz.
Setup and Hold Time Adjustments. You cannot change the setup and hold time for
any signal group.
Nonintrusive Acquisition. Acquiring Utopia2 bus cycles is nonintrusive to the
target system. That is, the TMS822 UTOPIA2 does not intercept, modify, or
present signals back to the target system.
Channel Groups. Channel groups required for clocking and disassembly for
TMS822 UTOPIA2 bus support are as follows:
Receive bus:
Address Group, Data Group, Control Group, RXCLAV Group, and L2PControl
Group.

UTOPIA Level 2 Plus. TMS822 UTOPIA2 support, when used with the Utopia
Level 2 plus does not decode the acquired PPP packets. The acquired information
is displayed and the disassembly identifies the packets.
Address Display. The address of the PHY port from which the cell is transmitted
or received is correct only when the custom clocking option is ATM Cells/PPP
Packets or ATM Cell Headers (5-bytes) option. The support displays the address
only when more than one physical device is involved. In a Single PHY operation,
the Address column is dashed out.
Trigger Programs. The Trigger Programs that are provided do not work when
ATM cells have Extended Header Bytes.
The disassembly shows correct information only when the appropriate disassembly and custom clocking options are chosen.
Table 1--1 shows the invalid combinations of disassembly and clocking option.

AAL 3/4:The TMS822 UTOPIA2 support decodes information up to the
SAR-PDU and to a certain extent the CPCS -PDU. The support decodes the
SAR-PDU to show details of the SAR-PDU Header and Trailer information and
identifies the SAR-PDU as to whether it is BOM, COM, EOM, or SSM.
The support identifies the two types of SAR -PDUs namely, Data-SAR-PDU and
Abort-SAR-PDU. The SAR-PDUs are further decoded to show the CPCS-PDU
header and trailer information based on whether it is BOM, EOM, COM, or
SSM.
Refer to the ITU-T I.363.3 B-ISDN ATM adaptation layer specification for
details about the PDU format.
AAL 5: The support decodes the information up to the SAR-PDU and identifies
the last SAR-PDU payload based on the AUU parameter. The support decodes
the CPCS trailer information (the CPCS trailer is in the last 8 octets of the last
SAR-PDU.)
Refer to the ITU-T I.363.5 B-ISDN ATM adaptation layer specification for
details about the PDU format.

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 TMS822 UTOPIA2 signals in the target system using a
test clip, follow these steps:
1. Power off your target system. It is not necessary to power off the logic
analyzer.
CAUTION. To prevent static damage, handle the target systems, 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 target system.
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.

Labeling P6434 Probes
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--5 through 3--16 starting on page 3--3 to connect the channel
probes to TMS822 UTOPIA2 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.
The TMS822 bus support package relies on the channel mapping and labeling
scheme for the P6434 Probes. Apply labels using the instructions described in the
P6434 Probe Instructions manual.

Operating Basics
Setting Up the Support
This section provides information on how to set up the support and covers the
following topics:
H Channel group definitions
H Clocking options
The information in this section is specific to the operations and functions of the
TMS822 UTOPIA2 support on any Tektronix logic analyzer for which the
support can be purchased. Information on basic operations describes general
tasks and functions.
Before you acquire and display disassembled data, you need to load the support
and specify the setups for clocking and triggering as described in the information
on basic operations. The support provides default values for each of these setups,
but you can change the setups as needed.

Setting Up the Support
Acquisition Setup. The support package consists of two different supports, one for
the Transmit Interface and the other for the Receive Interface. You must make
connections and load the appropriate package for the desired support. The
TMS822 support will affect the logic analyzer setup menus (and submenus) by
modifying existing fields, and adding UTOPIA2 bus-specific fields. The
TMS822 adds the selection ‘UTOPIA2RX’ to the ‘Load Support Package’ dialog
box, under the File pulldown menu when the support package for the Receive
Interface is loaded.
On the logic analyzer, the TMS822 support adds the selection‘UTOPIA2TX’ to
the ‘Load Support Package’ dialog box, under the File pulldown menu when the
support package for the Transmit Interface is loaded. Once the corresponding
support has been loaded, the ‘Custom’ clocking mode selection in the logic
analyzer setup menu is also enabled. ‘Custom’ is the default selection whenever
the ‘UTOPIA2TX’ or ‘UTOPIA2RX’ support loads.
NOTE. This procedure is applicable for acquisitions from UTOPIA Level 1
systems also.
Channel Group Definitions
The software automatically defines channel groups for the support. The channel
groups for the TMS822 UTOPIA2 support for the Receive bus are Address,
Data, Control, RXCLAV, Parity and L2PControl.

Clocking
Clocking Options
Custom Clocking
The TMS822 support offers a bus-specific clocking mode for the TMS822
UTOPIA2 bus interface. This clocking mode is the default selection whenever
you load the UTOPIA2 support.
Disassembly is not correct when using the Internal or External clocking modes.
Information on basic operations in the logic analyzer online help describes how
to use these clock selections for general purpose analysis.
A special clocking program is loaded on the module every time you load the
UTOPIA2 support. This special clocking is called Custom.
With Custom clocking, the module logs in signals from multiple channel groups
at different times when the signals are valid on the Utopia2 bus. The module then
sends all the logged in signals to the trigger machine and to the acquisition
memory of the module for storage.
In the custom mode, the support uses a TxClk as the clock for the transmit
