USB 3.1 Power Delivery Compliance Test Suite

25 January 2016 – Teledyne LeCroy announced the release of the Power Delivery Compliance Suite for the Voyager M310C SuperSpeed USB 3.1 protocol verification platform. Based on the Power Delivery (PD) Compliance Plan v1.0, this automated test suite, allows developers to verify functionality, error recovery, and compliance for PD chipsets and end-products.

Integrated in Teledyne LeCroy's flagship Voyager M310C USB 3.1 test platform, the Power Delivery Compliance Suite utilizes emulation scripts to mimic PD link partner behaviors. The system initiates and responds to PD messages while analyzing the real response from the device-under-test. It communicates directly over Type-C cabling and generates pass/fail reports to provide a fully automated test suite for Power Delivery protocol.

Built on the same open architecture as Teledyne LeCroy's USB 3.1 Link Layer test suite, the PD Compliance Suite includes full source code for all PD test cases. This provides developers with a comprehensive library of test scripts that can be easily re-purposed for custom test development. The Power Delivery Compliance Suite addresses chapter 5 physical layer, chapter 6 protocol layer, and chapter 7 power supply test cases from the USB Power Delivery 2.0 Specification. As the test specifications are updated for Power Delivery 3.0, any software updates will be provided at no cost to PD Compliance Suite end-users.

"The release of the new PD Compliance Suite is another proof point that Voyager M310C remains the gold standard in test and verification for the USB developer community"; said Joe Mendolia, Vice President of Marketing at Teledyne LeCroy's Protocol Solutions Group. "Designed from the outset to address the range of USB 3.1, Type-C and Power Delivery test specifications, the Voyager M310C platform allows developers to pre-test their devices for USB compliance. The slogan 'know-before-you-go' means designers can uncover compliance issues before beginning the certification process and gain additional confidence that their products will interoperate with other USB devices."

The first protocol analyzer solution to feature native USB Type-C connectors, the Voyager M310C combined with the Power Delivery Compliance Suite can test PD enabled electronic markers as well as full-featured PD chipset implementations. The exerciser can emulate a full 100 Watt source or 100 Watt sink (with added programmable load). It can precisely direct devices into PD role swap and alternate mode behaviors. The system provides real-time voltage and power monitoring to provide continuous VBUS measurements for verifying power transitions and timing.

USB Protocol Suite Version 7.26 is also now released for the Voyager M310C system. This release adds support for numerous Power Delivery enhancements including ability to inject and trigger on errors in PD message frames. To simplify Power Delivery debug, this release automatically reports PD errors in the Traffic Summary; and provides a new real-time PD Status View showing state transitions on the USB Type-C Communication Channel.
