  • Teledyne LeCroy’s new PCI Express (PCIe) 5.0 with Compute Express Link (CXL) delivers high performance for testing of high-speed device and system designs
  • Enables rigorous device testing and supports traffic generation and device/host emulation at all layers

Teledyne LeCroy has announced the release of its new PCI Express (PCIe) 5.0 with Compute Express Link (CXL) protocol exerciser, the Summit Z516 with which high-performance 32 GT/s traffic generation on devices with link widths up to 16 lanes can be achieved, enabling testing of high-speed device and system designs. 

For high-performance computing, validation of devices and systems is critical. 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 device also helps validate the incoming wave of CXL-based systems, a new high-speed CPU-to-Device and CPU-to-Memory interconnect designed to accelerate next-generation data centre 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, creating a low overall system cost. 

“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.”

The Summit Z516 PCIe 5.0 Protocol Exerciser with support for CXL is currently available to order.
