D9040MPHC MIPI M-PHY Compliance Test Software

Data Sheets

Introduction

Keysight Technologies’ MIPI® M-PHY® conformance test software for Infiniium oscilloscopes gives you a fast, easy way to validate and debug your embedded M-PHY data links. The M-PHY electrical test software allows you to automatically execute M-PHY electrical checklist tests for DigRF v4, UniPro, LLI, UFS, SSIC and M-PCIe architectures, and displays the results in a flexible report format. In addition to the measurement data, the report provides margin analysis that shows how closely your product passed or failed each test. The M-PHY conformance test software performs a wide range of tests required to meet the physical layer requirements per section 5 of the MIPI Alliance Specification for M-PHY and section 1 of the M-PHY Conformance Test Suite (CTS). The M-PHY conformance test software helps you execute the most difficult physical layer tests for transmitters (TX tests only) that can be measured with a high bandwidth real-time digital oscilloscope. Although there are not currently any requirements for physical layer compliance verification, it is highly recommended that every MIPI M-PHY link be tested against the limits of the physical layer specification to ensure that it conforms to the specification and to minimize concerns with protocol level interoperability.

Key features

The M-PHY conformance test software offers several features to simplify design validation:

• Complete MIPI Alliance Specification for M-PHY v3.0, v4.0 and v4.1, section 5 and M-PHY v3.0, v4.0 and v4.1 CTS v1.0, section 1.

• User selection of tests and configuration of data rate. – Automated scope measurement setup and programming for increased accuracy, time-savings and repeatability.

• Advanced debug modes for troubleshooting.

• Automated margin analysis and pass/fail conformance reporting.

• Fully integrated SigTest tool for Gear4 Eye diagram test.

• UFS reference clock test (informative).

 

With the M-PHY conformance test software, you can use the same oscilloscope you use for everyday debugging to perform automated testing and margin analysis based on not only the MIPI Alliance Specification for M-PHY v3.0 but also v4.0 and v4.1 section 5 requirements and M-PHY CTS v3.0, v4.0 and v4.1, section 1. UFS reference clock test based on JEDEC specification for UFS v3.0.

Save Time with the M-PHY Conformance Application

The M-PHY conformance test software saves you time by setting the stage for automatic execution of required electrical tests. The primary difficulties associated with performing electrical tests for M-PHY is connecting the oscilloscope to the target device, correctly configuring the oscilloscope’s measurement system for ultimate accuracy, issuing the proper commands to perform the tests and then analyzing the measured results by comparing them to limits published in the specification. The M-PHY conformance test software automates this work to provide rapid, accurate and repeatable test execution. In addition, if you discover a problem with your product, debug tools in the oscilloscope are available to aid in root-cause analysis.

Easy Test Definition

The M-PHY conformance test software extends the ease-of-use advantages of Keysight’s Infiniium oscilloscopes to testing M-PHY designs. The Keysight automated test engine walks you quickly through the steps required to define and configure the tests, execute the tests and view the test results. You can select a category of tests all at once or specify individual tests. The user interface is oriented to minimize unnecessary reconnections, which saves time and ensures accuracy and repeatability of tests. You can save tests and configurations as project files and recall them later for quick re-testing or review of a previous test. Straightforward menus let you perform tests with a minimum of mouse clicks.
