Protocol Decoding

Comprehensive Tunneling Support

The Voyager utilizes the legendary CATC Trace - the industry's de facto standard display and shows all packets labeled and interleaved in a single view. Traffic from the logical USB4 and side-band channels can be individually filtered, searched or exported from the trace. While in line, the analyzer will record and display all register reads and writes to provide an unambiguous picture of the router and path configuration process. To simplify analysis tasks, the Hop ID window allows precise hiding of extraneous traffic using Hop ID and Protocol Defined Function (PDF).

    All the logical link sub-states are recorded and displayed including SLOS patterns, training sequences and DESKEW ordered sets. During path configuration, all register Read Request / Response transactions are grouped to simplify debug of router enumeration. SBU register transactions are parsed to automatically assign protocols to Hop IDs. For Gen-T links, the new header, framing and packet structure updates are fully supported. The PD handshake commands are also captured and decoded.

      USB4 tunneled traffic can be exported to Teledyne LeCroy’s full-featured PCIe suite, Video Protocol Suite, or USB Suite for more detailed decoding and analysis of encapsulated protocols. Comprehensive decoding of tunneled transactions provides a coherent view of the underlying PCIe, USB or DP application traffic within the USB4 fabric.

        Error Detection

        The Voyager M480x can detect real USB 3.2, USB4 and PD protocol errors. At the lower layers, training sequences, SCR content and CRC errors are automatically verified and flagged. Control Packet Timing is checked along with many of the USB4 logical layer timing requirements. Dozens of checks are reported for PD and USB 3.2 protocol including occupying reserved fields, invalid frame size, and correctable bit-errors.

        Measure and verify VBUS and CC voltages with Power Tracker™

        The Voyager M480x Power Tracker option monitors and displays vBus power and current graphically in a time-line format. The voltages are synchronized to trace events allowing users to verify power state transitions at the protocol and electrical layers. Separate power graphs are provided for CC and VCONN making it easy to debug logical Type-C state transitions.

        Gen T Exerciser option

        USB4 Exerciser Option

        The exerciser adds a flexible traffic generation capability for USB4 80Gb/s and Thunderbolt™ 5 to the Voyager M480x platform. It allows users to transmit custom packets over standard USB Type-C cables with low-level control of headers, payloads, timing, and link states. Seamlessly integrated with the protocol analyzer, the M480x exerciser can emulate host or device router operations while recording the real response from the DUT. Leveraging the same proven architecture developed for SuperSpeed USB, the M480x exerciser adds Gen 4x2, Gen3x2 and Gen2x2 support allowing users to perform initial power-on, functional and compliance testing for next generation USB4-V2 chipsets.

        Power Tracker

        The Voyager Power Tracker option monitors Vbus, CC and VCONN voltage/current and displays power levels graphically in a time line format. This power information is synchronized to the trace allowing users to verify power state transitions at the protocol and electrical layers. The Power Tracker continually samples voltage during normal operations. It includes markers and delta measurements with point and click ease. Required for running PD Compliance Suite, the Power Tracker is invaluable for validating VBUS, PD, Type-C and Vconn behaviors.

        SimPASS USB

        SimPASS USB brings the powerful Teledyne LeCroy data traffic analysis capabilities commonly used for post-silicon testing to the simulation environment. Users of cutting edge simulation tools can now export and view test vectors directly in the Teledyne LeCroy USB trace viewer.

        usb simpass software

        SimPASS USB now supports USB4 40Gb/s and 80Gb/s simulation files. This allows vendors to generate RTL vector files (that describe USB I/O traffic in the pre-silicon phase) and then display and analyze these exchanges in the same way as hardware-derived trace files in the post-silicon phase. Viewing simulation files that illustrate potential flaws in data and transaction packets from the I/O stream, SimPASS enables developers to more completely test and debug the logic design before committing the design to silicon. Issues such as flaws in power state transitions, improper credit flow exchanges and marginal timing handshakes can be discovered, tracked to their source, and resolved, resulting in faster time-to-market and lower development costs for SoCs. During any redesign cycle, fixes for bugs (identified in the previous cycle) can be verified by re-testing the fixes during simulation using the SimPASS software.

        Gen T Exerciser option

        The Teledyne LeCroy Gen T Exerciser option enables comprehensive functional and compliance testing, helping ensure reliable operation and faster performance for next-generation USB4 Gen T hosts and devices. When combined with the Voyager M4x or M480x Exerciser system, the Gen T option provides precise control of Gen T protocol transactions. This option is a requirement to gain access to the Gen T Compliance tests, which will be added in an upcoming USB4-CV tool from the USB Implementers Forum (USB-IF). There are currently 20 test cases fully aligned with the latest USB-IF specifications and designed to validate Gen T device enumeration, functionality and error recovery. Part#: USB-AC60-V08-A.
