The rapid increase of AI (artificial intelligence) related workloads in data centres and edge computing mean that data centre system designers need to provide new higher speed devices within reduced design cycles. New PCIe devices will need to keep up with Ethernet network interfaces in data centres and the emergence of CXL (compute express link).
To prepare for the PCIe 6.0 move to pulse amplitude modulation 4-level (PAM4), customers need a smooth transition from PCIe 5.0 to 6.0, where the integrity of PCIe measurements are backed by leading-edge tools and comply with PCIe specifications. With shrinking design cycles, end-to-end solutions from simulation to validation through the layers of the stack are required.
Keysight is now providing a comprehensive physical layer test solution, approved by the Peripheral Component Interconnect Special Interest Group (PCI-SIG) to test transmitters and receivers for all generations of the PCIe specification, which is currently supported by the PCI-SIG integrators list. Keysight has extended the portfolio to cover PCIe protocol, making it the first end-to-end solution from simulation to full stack validation.
"Keysight has been a member of the PCI-SIG since its founding in 1992 and has been on the PCI-SIG Board of Directors starting in 2007. Keysight participates in many working groups to enable testability and early availability of various standards to the industry," said Dr. Joachim Peerlings, vice president of network and data centre solutions at Keysight Technologies. "Keysight is launching a complete PCIe testing solution from simulation to protocol, enabling customers to evaluate and validate the true performance margins of their designs."
Keysight's new PCIe test solution leverages the company's physical layer-system simulation; physical layer interconnect, transmitter (Tx) and receiver (Rx) test – to offer a new protocol layer test solution consisting of hardware and software products.
Key customer benefits include:
- Interoperability and support across the entire design cycle from a single vendor.
- A Keysight Infiniium UXR-Series real-time oscilloscope for accurate PAM4 PCIe 6.0 Tx measurements and Rx calibrations to enable low intrinsic noise with 110 GHz bandwidth to provide future proof capabilities.
- Investment protection with the Keysight M8040A Bit Error Ratio Tester (BERT), which utilises the same hardware for non-return to zero (NRZ) and PAM-4 measurements.
- Superior signal integrity that enables engineers to focus on protocol bugs rather than interposer signalling issues.
- Fast transmitter phased locked loop (PLL) bandwidth measurements to reduce the measurement time from hours to seconds.
- End-to-end verification of components and sub-systems across the product workflow with common software platforms and built-in test automation capabilities.
