Industry’s First Traffic Generator and Emulator for PCI Express™ 5.0 and Compute Express Link™

The Summit™ Z516 protocol exerciser simplifies design validation and interoperability stress testing for high-speed (32GT/s at x16 link width) devices and systems


Milpitas, CA, September 15, 2020 – Teledyne LeCroy, the worldwide leader in protocol test solutions, today announced the Summit Z516 release, a new PCI Express (PCIe) 5.0 with Compute Express Link (CXL) protocol exerciser for testing high-speed device and system designs. The Summit Z516 exerciser provides high performance 32 GT/s traffic generation on devices with link widths up to 16 lanes.   

Emulation using the Teledyne LeCroy exerciser is critical for validation of devices and systems used in high performance computing.  The Summit Z516 enables rigorous PCIe 5.0 device testing by generating flits on the flex bus within the link and transaction layers and supporting traffic generation and device/host emulation at all layers. The Summit Z516 also helps validate the coming wave of CXL-based systems, a new high-speed CPU-to-Device and CPU-to-Memory interconnect designed to accelerate next-generation data center performance. CXL technology maintains memory coherency between the CPU memory space and memory on attached devices, which allows resource sharing for higher performance, lower latency, and reduced software stack complexity, driving to lower overall system cost. The Summit Z516 joins the Z58, M5x, and T54 in the line of Summit analyzers and exercisers for PCIe 5.0, supporting validation of product designs and interoperability stress testing for both PCIe and CXL technologies. 

 “Our commitment to providing high-quality development tools and our long engagement in the PCIe protocol tool market has allowed us to develop and provide the most useful decodes, analysis and reports that expedite testing and make testing strategies successful.” said Joe Mendolia, Vice President of Marketing, Protocol Solutions Group, Teledyne LeCroy. “Users who are moving to CXL on Teledyne LeCroy get the benefit of all the previous investment made in our PCIe test equipment and do not have to wait for important features to mature on alternative solutions.”

“Industry excitement continues to grow for the CXL protocol for high-performance accelerator interconnect,” said Michael Hall, Director of Technology and Ecosystem Enabling, Intel Corporation. “The hardware and software ecosystem surrounding CXL, such as Teledyne LeCroy’s latest test and validation tools, is quickly maturing to enable a smooth transition and rapid ramp of the technology.”
