Description

The D9050PCIC PCI Express electrical performance validation and compliance software for PCI Express 5.0 provides you with a fast and easy way to verify and debug your PCI Express 5.0 design for both silicon validation (as per the PCIe® 5.0 BASE specification) as well as for PCI Express 5.0 add-in cards and motherboard systems (as per the PCIe 5.0 CEM specification).

The PCI Express electrical test software allows you to automatically execute PCI Express electrical transmitter tests, and it displays the results in a flexible report format. In addition to the measurement data, the report provides a margin analysis that shows how closely your device passed or failed each test.

The D9050PCIC PCI Express electrical performance validation and compliance software performs a wide range of electrical tests as per the PCI Express PCI Express 5.0 specification only and supports testing transmitters that operate at 32, 16, 8, 5, and 2.5 GT/s. In addition to full swing (800 mV) testing, the software also supports testing for low-power, half-swing devices (400 mV).

PCI Express Compliance Testing

To pass signal quality testing at a PCI-SIG-sponsored compliance workshop, your product must successfully pass “Gold Suite” testing, based on the PCI-SIG SigTest application. The SigTest application tests your device against the minimum signal-quality performance requirements for PCI. If you are developing receivers and transmitters for add-in boards and system motherboards, the D9050PCIC PCI Express electrical test software helps you execute the SigTest tests and additional oscilloscope already completed tests.

While SigTest tests provide a good overview of PCI Express electrical signal quality, they address only a small subset of the electrical compliance measurements specified in the PCI-SIG specification. The SigTest application also provides minimal reporting capability with pass/fail indication and measurement values and has limited debugging capabilities to decipher eye mask violations or excessive jitter.

For PCI Express 5.0 measurements, the software automatically calculates uncorrelated total jitter, uncorrelated deterministic jitter, uncorrelated PWJ necessary for validating new PCIe 5.0 compliant chipsets.

Benefits

PCI Express electrical test software benefits

The D9050PCIC PCI Express electrical test software saves you time by setting the stage for automatic execution of PCI Express electrical tests. Part of the difficulty of performing electrical tests for PCI Express is hooking up the oscilloscope, loading the proper setup files, and then analyzing the measured results by comparing them to limits published in the specification. The PCI Express electrical test software does much of this work for you. In addition, if you discover a problem with your device, robust debug tools are available to aid in root-cause analysis.

The D9050PCIC software also has an integrated interface for controlling the InfiniiSim Waveform Transformation Toolset for de-embedding of test fixtures and for easily adding the appropriate loss functions needed to complete CEM 5.0 testing at 32GT/s. Introduced with PCIe 2.0, de-embedding of test fixtures utilizes S-parameters as input to create a de-embed model that helps to restore high frequency signal content that is often lost or significantly attenuated by test fixtures and cables. This can help to recover significant jitter margin normally lost to fixtures used in a test setup. This helps ensure consistent run-to-run setup of the instrumentation, saving you time and providing consistent and accurate receive test results. As an alternative to de-embedding using s-parameter files, the D9050PCIC also supports the use of selecting a PCIe 5.0 CTLE equalization level to help compensate for break-out board losses.

Easy Test Definition

The D9050PCIC PCI Express electrical test software extends the ease-of-use advantages of Keysight’s Infiniium oscilloscopes to testing PCI Express designs. The Keysight automated test engine walks you quickly through the steps required to define the tests, set up the tests, perform the tests, and view the test results. You can select a category of tests all at once or specify individual tests. You can save tests and configurations as project files and recall them later for quick testing and review of previous test results. Straightforward menus let you perform tests with a minimum of mouse clicks.
