World's First Public Showing of "Compute Express Link" (CXL) Showcased by Teledyne LeCroy at DesignCon

CXL Protocol Analyzers for High-Performance Enterprise Systems and Accelerators

SANTA CLARA, Calif., Jan. 29, 2020 — (PRNewswire) — DesignCon – Teledyne LeCroy, the worldwide leader in protocol test solutions, today showcased its support for the newly announced Compute Express Link (CXL) Protocol on its Summit PCI Express® (PCIe®) protocol analyzers.  The Teledyne LeCroy protocol analyzer monitors and verifies the operation of the CXL protocol bus between host and device and is used by firmware and driver developers for capturing, recording, and analyzing both the PCIe and CXL data. The Summit M5x and the Summit T54 systems are the industry's first high speed protocol analyzers capable of capturing 32 GT/s PCIe traffic as well as analyzing and decoding the newly defined CXL protocol. Teledyne LeCroy will showcase its CXL Protocol Analysis at DesignCon 2020 in booth #513.

"Teledyne LeCroy protocol analyzers and exercisers have been at the forefront of PCI Express development since its inception, working closely with the computer industry over the last decade to provide decodes, analysis and reports that shorten time spent during development and testing of PCIe systems, storage and IoT technology," said Joe Mendolia, Vice President of Marketing, Protocol Solutions Group, Teledyne LeCroy. "Teledyne LeCroy's existing high-speed protocol analytics enable access to the broadest array of features available in the market".

"The CXL protocol is anticipated to set the lead for high-performance accelerator interconnect," said Jim Pappas, Director of Technology Initiatives, Intel Corporation. "Test and IP solutions from companies including Teledyne LeCroy and Synopsys show the robust growth of the CXL ecosystem and help enable a smooth transition and rapid industry adoption."

Both the Summit M5x protocol analyzer, first demonstrated last year at the June PCI SIG DevCon as the world's first PCIe 5.0 analyzer, and the Summit T54 protocol analyzer that supports PCIe 5.0 at speeds up to 32GT/s and  link widths up to x4, can be easily upgraded through a software license that adds CXL support. Like other analyzers from Teledyne LeCroy, both systems 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 more quickly.
