Protocol Analyzer for PCI Express 4.0 Technology

TLC T41617 October 2016 – Teledyne LeCroy launched its new PCI Express (PCIe) protocol analyzer for capturing, recording and analyzing PCIe 4.0 systems and devices. The Summit T416 analyzer is the computer industry's first high speed PCIe 4.0 protocol analyzer that meets the challenge of 16GT/s and up to x16 lane width protocol analysis. Many PCIe 4.0 product designs are already in progress using the PCIe 4.0 specification.

Companies at this stage are currently working with the Teledyne LeCroy Summit Z416 protocol exerciser for PCIe 4.0 shipped early this year for host system emulation with their testing needs. This combination of a protocol analyzer and exerciser make Teledyne LeCroy the only supplier of protocol test and development tools for PCIe Gen 4. High speed interposers that provide protocol analyzer connectivity to CEM or other form factor sockets on system boards will still continue to be the principle way to capture PCIe traffic into the protocol analyzer.

The Summit T416 protocol analyzer features support for PCIe 4.0 at a speed of 16GT/s and up to x16 lane width. The protocol analyzer memory buffer is the deepest in the industry at 128GB. The protocol analyzer can be controlled through USB for remote networked control through a 1000baseT Ethernet to a windows system. The protocol analyzer can be synchronized with other high speed protocol analyzers from Teledyne LeCroy.

"Now that the Summit T416 protocol analyzer has been added to the existing PCIe 4.0 portfolio of products including the Summit Z416 protocol exerciser, the combination of both a full featured analyzer and exerciser will make driver and firmware development more productive and allow more extensive testing coverage", said John Wiedemeier, Senior Product Marketing Manager, Teledyne LeCroy's PCI Express Group. "Companies who develop servers, networks, storage systems and solid state drives (SSDs) will find these tools, as well as our currently available Verification Load Board, Verification Base Board and PSP400 test platform, essential to ensure design performance."

The Summit T416 protocol analyzer features the latest in storage protocol decoding including NVM Express (NVMe) and SATA Express. It is also the only protocol analyzer to support the latest in NVMe management technology described in the NVM Express Management Interface (NVMe-MI) protocol specification. For example, some PCIe analyzers only support PCIe in-band capture for NVMe-MI but the Summit T416 can capture simultaneously in-band PCIe and out-of-band SMBus protocol traffic. Communications between applications using the Trusted Computing Group's Enterprise and Opal security can be decoded to confirm if accurate transmission of data is occurring.

As PCIe systems move toward implementing IO virtualization, the Summit T416 protocol analyzer is fully capable of decoding and describing virtualized systems in a multitude of different configurations. The CATC Trace View, along with the recently added spreadsheet view, NVMe queue characterization tables, and LTSSM state views help users quickly come up to speed on how well their devices and systems are behaving in real world environments. Developers that need to get down to the byte level and see traffic just before and after deskew can do it this with the BitTracer feature. BitTracer records the bytes exactly as they come across the link, allowing debugging of PHY layer problems and combining the features of a logic analyzer format with a decoded protocol analyzer format.

The Summit T416 protocol analyzer uses high speed Interposers capable of tapping any device under test (DUT). These interposers utilize the T.A.P.4 technology from Teledyne LeCroy that ensures transparent acquisition of 16 GT/s PCIe transmission between hosts and devices. The interposers come in x1, x4, x8 and x16 lane widths that can cover testing requirements for all CEM connectors. In addition, Teledyne LeCroy is also releasing a PCIe 4.0 Test Platform that is a two CEM-socket active backplane with power supplies capable of supporting 16 GT/s bus transactions for testing CEM form factor devices. This Test Platform contains a high speed interposer that can capture traffic between the two CEM-socket. Ideally the test platform can be used for testing with the Summit Z416 protocol exerciser and the DUT.

"Teledyne LeCroy is actively involved in the PCIe industry providing analysis and test solutions around the world. We are committed to providing high quality development tools that will help expedite your testing productivity," said Joe Mendolia, Vice President of Marketing, Protocol Solutions Group, Teledyne LeCroy." We take our customer commitments seriously and strive for customer satisfaction in all that we do."

Teledyne LeCroy protocol analyzers and exercisers have been at the forefront of PCI Express development working closely with the computer industry over the last decade to provide the analysis features companies have needed for PCIe storage and IoT technology development. All Teledyne LeCroy protocol analysis and test products feature a hierarchical display, real-time statistics, protocol traffic summaries, detailed error reports, powerful scripting, and the ability to create user-defined test reports, which allow developers to troubleshoot intricate problems and finish their projects on time. Users of Teledyne LeCroy systems appreciate the rich library of decodes and analysis capabilities that are available on all of Teledyne LeCroy's PCIe test tools.


The Summit T416 PCIe 4.0 Protocol Analyzer, PCIe 4.0 x1, x4, x8, x16 Interposers and PCIe 4.0 Test Platform are currently available to order.
