The Most Comprehensive and Only Protocol Aware Test Tools for PCI EXPRESS 3.0

2

New Tools for New Test RequirementsRequirements for serial data testing unique to PCI Express® 3.0 place new demands on the traditional physical layer test tools. Not only does the specification mandate that the receiver tester be protocol aware, but certain other characteristics of PCI Express 3.0, such as dynamic equalization, essentially require combined physical/protocol layer test capabilities for validation and debug. Only Teledyne LeCroy has the comprehensive set of physical layer, protocol layer, and network analysis tools for complete PCI Express 3.0 transmitter, receiver, and channel testing.

Teledyne LeCroy’s PeRT3 ™ is the only

protocol-aware test equipment that is

also capable of bit error rate testing.

This greatly simplifies communication

with the receiver, and allows significant

test automation. In addition, PCI

Express 3.0 introduces the concept of

a real-time exchange of equalization

parameters to maximize signal

fidelity at the transmitter and receiver.

Teledyne LeCroy’s PeRT3, PCI Express

3.0 Decode Annotation and

ProtoSync™ toolsets provide direct

validation of link equalization

response time with visual evidence of

the time and traffic during the

equalization phase.

Teledyne LeCroy’s SDA 820Zi-A Serial

Data Analyzer provides up to 20 GHz

on all 4 channels with pristine signal

fidelity for the most comprehensive

validation, debug and analysis of the

physical layer signal using a wide

variety of built-in oscilloscope tools.

Teledyne LeCroy also provides

complete solutions for protocol

analysis on up to 16 lanes of traffic,

and also provides network analysis of

4-port systems for the best

understanding of crosstalk effects.

The Teledyne LeCroy QPHY-PCIe3-

Tx-Rx compliance automation software

integrates the PeRT3, SDA 8 Zi-A

oscilloscope, and PCISIG compliance

base board to provide a closed-loop

end-to-end test solution complete with

documented pass/fail reporting.

The Perfect Oscilloscope and Serial Data Analysis Tools for PCI Express 3.0 TestingTeledyne LeCroy SDA 8 Zi-A Series of

oscilloscopes upgraded to include

SDAIII-CompleteLinQ is the perfect

instruments for performing PCI

Express 3.0 compliance

measurements. More importantly,

these tools are specially designed for

debugging compliance failures,

allowing the engineers to quickly find

the root cause of serial data problems.

Complete Link Testing SDAIII-CompleteLinQ includes

multilane serial data, eye, jitter, noise

and crosstalk analysis, and integrates

the Doctor™ II toolkit for equalization

and channel/fixture de-embedding and

emulation. These features are

extremely useful for PCI Express 3.0

during channel emulation, simulating

the effects of transmitter and receiver

equalization and analyzing multiple

transmitter channels simultaneously.

Multi-Point Simultaneous Analysis SDAIII-CompleteLinQ is capable of

analyzing multiple differential signals.

Users can choose to analyze the

transmitted signals at different stages

of the transmission path, or analyze

multiple transmitter channels of an

add-in card or system board. For

example, Lane 1 can show the raw

capture of a Tx output, Lane 2 can

show the effects of a long compliance

channel on the signal after embedding

the compliance channel, Lane 3 can

show the effects of CTLE after

emulating the high loss compliance

channel, Lane 4 can show the effects

of DFE after CTLE. In addition to

testing multiple transmitter channels

simultaneously, SDAIII has the

deepest analysis toolbox for rapidly

pinpointing sources of jitter and

crosstalk, including dual-Dirac jitter

and noise measurements, tracks,

histograms and spectra. Plots are

displayed using LaneScape

Comparison Mode, a unique display

capability that compares results from

1, 2 or all lanes at a time.

Investment Protection The SDA 8 Zi-A Series of oscilloscopes

provides the best asset investment

protection available. Engineers

working on 3rd generation

technologies can be confident that

WaveMaster 8 Zi-A will support 4th

generation technologies in the future.

Transmitter Compliance Testing When you add QualiPHY PCI Express

3.0 (QPHY-PCIE3-TX-RX) to the

SDA 8 Zi-A oscilloscope, you have the

ideal PCI Express 3.0 Compliance

Test Instrument.

QPHY-PCIE3-Tx-Rx is an automated

compliance test package for PCI

Express 3.0 transmitter compliance

testing. It provides connection

diagrams to ensure the proper setup

for the required measurements,

automates the oscilloscope for

performing these measurements,

and provides a comprehensive report

of results including screenshots.

QPHY-PCIE3-TX-RX uses all of the

powerful oscilloscope features to

perform the transmitter compliance

tests as described by the PCI Express

3.0 specifications.

Transmitter Test Receiver Test S-parameter and TDRLink Equalization Test Protocol TestTransmitter Test Receiver Test S-parameter and TDRTransmitter and ReceiverTest Protocol Test

Using the PeRT3 Phoenix for Transmitter TestingTransmitter link equalization response test requires the test instrument to

handshake with the DUT in the protocol layer to test the DUT’s response to

different equalization setting requests. Teledyne LeCroy PeRT3 Phoenix is

specifically designed to address this requirement for PCI Express 3.0.

Receiver Compliance Testing The PeRT3 (Protocol-enabled Receiver

and Transmitter Tolerance Tester) fills

the space between physical layer test

and protocol test, providing a new and

more intelligent capability for perfor-

mance testing of receivers and trans-

mitters. The PeRT3 Phoenix is a new

addition to the PeRT3 family of

products designed to address PCI

Express 3.0 test requirements.

In order to meet the increasingly

complex designs of today’s serial data

receivers, the PeRT3 Phoenix expands

the bit rate range up to 8.5 Gb/s and

offers new signal stress sources and

built-in three tap de-emphasis control

to address new serial data standards.

At the same time, Phoenix continues

to focus on protocol awareness to

meet the need to communicate with

the Device Under Test (DUT) into

proper test modes and train the

DUT’s receiver equalization setting

prior to performing receiver jitter

tolerance testing.

Complete Compliance Test Environment Receiver testing is a critical area for

PCI Express 3.0 Compliance.The

PeRT3 Phoenix is designed to test the

receiver under conditions of proper

equalization training, by performing

loopback initialization and by

introducing different stress types.

Because the system combines

protocol awareness with complete

stress jitter profile, the PeRT3 Phoenix

has revolutionized the receiver testing

architecture and has helped to define

the PCI Express 3.0 compliance

testing methodology.

Complete Characterization in Development

The biggest challenge for receiver

compliance testing for PCI Express

3.0 is how the receiver performs

dynamic equalization training of both

the receiver equalization parameters

and the proper selection of transmitter

equalization presets. The PeRT3

Phoenix can generate both 8b/10b and

128b/130b encoded data to establish

PCI Express 3.0 connectivity, and can

perform transmitter equalization

preset negotiation while the receiver

optimizes the receiver equalization

parameters. The PeRT3 Phoenix

satisfies the 500 ns timing

requirement for preset response and

thus makes this instrument the

perfect tool for validation and

characterization of the dynamic

equalization design.

Calibrating the Jitter Output of the PhoenixReceiver test specifications require

calibration of the jitter output

sources for the test instrument.

When using the PeRT3 in

conjunction with an SDA 8 Zi-A

oscilloscope, this calibration process

can be fully automated through the

QPHY-PCIe3-TX-RX software option.

What is Link Equalization?Link equalization as specified in PCI

Express 3.0 consists of transmitter

equalization through a 3 tap FIR filter

and receiver equalization through

CTLE and DFE filters. During link

equalization training, the 3 tap FIR

filter parameters can be recalled by

presets or specific cursor values of

de-emphasis and preshoot. Then for

each setting of TXEQ, the receiver

will adjust CTLE and DFE parameters

for maximum eye opening. Due to

the dynamic nature of the

transmission path between endpoint

and the root-complex, link

equalization training takes place every

time a system powers up so a

different set of TXEQ and RXEQ

value can be selected for different

combinations of system boards and

add-in cards. The four phases of

LTSSM allows for both the root-

complex and the endpoint to select

each other’s ideal TXEQ settings with

corresponding RXEQ parameters.

How to test Link Equalization During link equalization testing, the

test equipment must have the ability

to communicate and track the DUT

through the LTSSM, while at the

same time generate reference TXEQ

signals and measure TXEQ responses

from the DUT. This calls for a class of

instruments that are protocol-aware

and can generate TXEQ signals with

jitter injection as specified by the PCI

Express 3.0 specifications. The PeRT3

Phoenix was designed for these

needs and is the only available test

equipment with these capabilities.

PeRT3 Phoenix combined with the

SDA8Zi-A’s PCI Express 3.0 decode

and protosync features can emulate

either a system board or an add-in

card to test the link training process.

The transmitter of the DUT will be

tested on its ability to generate

requested preset and cursor values

and receiver will be tested on its

ability to adjust RXEQ parameters and

select the proper TXEQ setting base

on Bit Error Rate Ratio.

Tools That Bridge Physical Layer and Link Layer

The PeRT3 Phoenix establishes PCI Express 3.0 connectivity, and can perform transmitter equalization preset negotiation (satisfying preset response timing requirements) while the receiver optimizes the receiver equalization parameters.

Testing PCI Express 3.0 Data Channels with the Teledyne LeCroy SPARQTransmitter, receiver, channel and crosstalk measurements can be made

with the Teledyne LeCroy SPARQ Signal Integrity Network Analyzer.

SPARQs are TDR/TDT-based analyzers that measure S-parameters with

a single button press, and at a fraction of the cost of a VNA. Fully

calibrated measurements can be made in minutes, and without any

need to connect or disconnect cables to calibration kit standards or

electronic calibration modules.

S-parameter measurements are at

the heart of the characterization and

verification of passive components,

and are needed to validate models and

for simulations. At less than half of the

price of a VNA, the SPARQ is an ideal

instrument for your lab. S-parameter

measurements are taken quickly and

easily by utilizing the industry’s first

built-in OSLT calibration kit. The

SPARQ performs calibration

automatically, without any user

intervention, eliminating the frustration

VNA users have with error-prone

manual calibration procedures, while

also eliminating the need for

expensive “ECAL” modules. In

addition to S-parameter results,

SPARQ calculates step and impulse

responses and Rho and Z profiles

normalized to a user’s risetime.

All measurements can be made in

both single-ended and mixed-mode

configurations, yielding differential

insertion loss, crosstalk and

impedance measurements needed.

Results are “simulation ready”,

using optional passivity, reciprocity

and causality enforcements, and

include a DC point, something that

cannot be done with a VNA. Adaptor

cables used to connect analyzer port

cables to PCI Express fixtures using

time-domain gating. All of these

features are standard.

time-domain gating procedure that

does not require any separate TRL or

OSLT calibration fixtures.

Crosstalk between all three signal pairs

can be quickly characterized using a

12-port SPARQ. With a single 12-port

measurement, NEXT and FEXT

between the six differential ports can

be measured. SPARQ models are

available ranging from 2 through

12 ports. For more information
