Teledyne LeCroy Announces PCI Express® 7.0 Protocol Exerciser

Industry first standalone PCIe^® 7.0 Protocol Exerciser, extends the Summit M616 Protocol Analyzer to deliver a complete validation and debug solution

MILPITAS, Calif., Sept. 17, 2026 /PRNewswire/ -- Teledyne LeCroy, the worldwide leader in protocol test solutions, today announced the release of the Summit™ Z74 Protocol Exerciser for PCI Express^® (PCIe^®) 7.0 technology, designed to accelerate the development, validation, and debug of next-generation PCIe devices and systems. Summit Z74 operates as a standalone protocol exerciser for controlled traffic generation, or pairs with the Summit M616 Protocol Analyzer to create a complete PCIe 7.0 analysis and exerciser solution. Together, the platforms give engineering teams the control and visibility needed to expose interoperability issues earlier, shorten debug cycles, and reduce development risk.

Artificial intelligence, machine learning, high-performance computing (HPC), cloud infrastructure, and advanced storage applications are driving the demand for faster, lower-latency interconnects. To meet that demand, PCIe 7.0 specification doubles the raw data rate of PCIe 6.0 specification from 64.0 GT/s to 128.0 GT/s and delivers up to 512 GB/s of bi-directional bandwidth in a x16 configuration. At these speeds, Pulse Amplitude Modulation 4-level (PAM4) signaling, FLIT-based protocol, and increasingly complex system architectures require validation tools that can generate precise protocol traffic, emulate real-world workloads, reproduce problem conditions, and provide deterministic control over PCIe link behavior throughout the development lifecycle.

The Summit Z74 addresses these challenges with a flexible architecture for PCIe 7.0 technology development. Used independently, it enables engineers to generate controlled protocol traffic, exercise device behavior, and validate responses under targeted conditions. Paired with the Summit M616 Protocol Analyzer, the Summit Z74 becomes part of a comprehensive debug and validation system that combines traffic generation with deep protocol capture, decode, analysis, and debug. This solution enables engineering teams to efficiently isolate, resolve and verify link training behavior, transaction-level issues, protocol errors, LTSSM transitions, interoperability challenges, and compliance-development concerns within an industry-leading and customer familiar Summit workflow.

"The rapid evolution of PCI Express technology to the PCIe 7.0 specification is enabling new levels of performance for AI, storage, and high-performance computing applications," said Al Yanes, PCI-SIG President and Chairperson. "Protocol test equipment accelerates validation and ecosystem readiness to help engineers address growing system complexity."

"The Summit Z74 extends our long-standing commitment to the PCIe design and test community," said Michael Romm, General Manager, Teledyne LeCroy Protocol Solutions Group. "Engineering teams can deploy the industry's first standalone PCIe 7.0 protocol exerciser or pair it with the Summit M616 to create a complete, familiar environment for traffic generation, protocol visibility, validation, and debug. This flexibility helps customers protect their test investment while confidently advancing next-generation PCIe designs."

Availability

The Summit Z74 and the Summit M616 are available to PCI Express technology development teams preparing for PCIe 7.0 specification validation programs. Please contact Teledyne LeCroy for additional product information, technical specifications, configuration guidance, and availability details.
