Introduction

The Agilent E2969A protocol test card (PTC) is a combination of software

and plug-in card that can be used for PCI Express compliance tests.

The PTC performs tests to verify and ensure compliance with PCI

Express as defined by the PCI-SIG.

The card runs on a PCI Express x1 lane at 2.5 Gbit/s. It is plugged into

one of the PCI Express slots of the target platform.

As an R&D engineer, you can use the PTC to validate the functional

compliance of your PCI Express-based designs, including chips, add-in

cards or systems.

The PTC provides a set of automated pre-programmed compliance tests

for testing both transaction layer and data link layer as well as power

management and configuration space. Furthermore, it monitors the

Introduction Test Modes

1-2 E2969-91020

behavior of the DUT (device under test) in response to certain error

conditions.

For more detailed analysis, the PTC provides a connector to Agilent’s

E2960 protocol analyzer. With the analyzer, you can monitor and analyze

captured PCI Express traffic between an adapter card and a system, for

example.

Further features include

• Field-upgradeable FPGA-based card

• USB 2.0 interface for programming and topology simulation mode

• Can act either as a PCI Express standalone add-in card, or as a PCI

Express interposer card for x1 operation

• Card supplied with two different software packages:

– The AIC test mode software which runs under Linux Operating

system with the PCI Express compliance tests for Add-In-Cards

– A windows software package that contains the AIC Tests for

Windows as well as the Topology Tests. This package contains also

some additional tools for checking and updating the Protocol Test

Card, which runs under Windows via the USB connector.

Test Modes Introduction

E2969-91020 1-3

Test Modes

The protocol test card provides three test modes:

• Add-In-Card test mode

• Known Endpoint test mode

• Topology test mode

The test software provides a list of tests for each of these modes. You can

select the mode and execute the tests from the graphical user interface.

The current version of the PTC only supports the Add-In-Card test mode

and Topology Test Mode. Known Endpoint test mode will be supported by

one of the next releases.

Add-In-Card Test Mode

In the Add-In-Card test mode, the PTC acts as a switch device between

the target platform and another PCI Express add-in card (DUT). The DUT

is plugged into the PCI Express slot on top of the PTC.

Though the upper slot of the PTC is capable of accepting up to x16 cards,

only x1 links are supported.

The tests in this mode check the correct behavior of the add-in card. The

test software communicates with the PTC using PCI Express commands

and performs various tests with the DUT.

In this mode it is necessary to power the PTC through the external power

connector. Any standard ATX Power Supply can be used for this purpose.

NOTE

Introduction Test Modes

1-4 E2969-91020

Known Endpoint Test Mode

In the Known Endpoint test mode, the PTC behaves like a known

endpoint device.

This mode is used for system testing. No other card can be plugged into

the PTC in this mode. The software runs various KEP tests to test the

systems behavior on certain error conditions.

The KEP mode will be supported by one of the next software releases.

Topology Mode

The Topology mode is used to test BIOS settings.

Controlled by software running on an external host connected through

USB, the PTC pretends to behave like a variety of PCI Express devices. No

other card can be plugged into the PTC in this mode.

All configuration accesses are handled via the software connected

through the USB link. No other accesses or transactions are supported in

this mode.

In this mode it is necessary to power the PTC through the external power

connector. Any standard ATX Power Supply can be used for this purpose.

NOTE

Installation

Test setups using the Agilent E2969A protocol test card (PTC) include the

following components:

• E2969A Protocol Test Card (PTC) card plugged into the target platform

• Add-In-Card Tests: PTC software running on the target platform

providing a graphical user interface used for controlling the tests and

monitoring the test results

• Topology Mode Tests: PTC software running running on an extra

controlling host PC connected to the test card through USB to run the

tests. This software package is also used for administration purposes.

This chapter shows how to install these components and verify their

operation.

Prerequisites

The PTC supports the PCI Express Specification 1.0a.

It is intended to be used standalone or as part of Intel’s Product

Development Kits (PDKs) for PCI Express Technology. The PTC integrates

into the PDK Software environment and tests.

For the Add-In-Card test mode as well as the Topology test mode, the PTC

must be plugged into a target platform, for example, the one provided

with the Intel PDK.

Installation Prerequisites

2-2 E2969-91020

PCI Express traffic must be scrambled as described in the PCI Express

specification. Unscrambled data transfer is not supported.

The Add-In-Card (AIC) tests run under the operating system Linux and

Windows. In case of AIC Tests under Linux, the target platform must

fulfill the following prerequisites:

• Red Hat Linux 9 installed, running the uniprocessor kernel

• “Kernel Development” package installed, including the Tk GUI toolkit

for Tcl, with shared libraries

• at least one free PCI Express slot that can be configured to run as x1

PCI Express connection

• CD-ROM drive available

In case of AIC Tests under Windows, the target platform must fulfill the

following prerequisites:

• Windows 2K or Windows XP installed

• at least one free PCI Express slot that can be configured to run as x1

PCI Express connection

• CD-ROM drive available

The controlling host for the Topology tests and administrative purposes

must fulfill the following prerequisites:

• 1 GHz PC with a Pentium 4 or equivalent

• Windows 2000 or Windows XP installed

• USB connector available

• CD-ROM drive available
