Essential Insights for Design PCIe® 6.0 Interconnects

White Papers

PCI Express® (PCIe®) is a serial communication protocol that has progressed through generations to enhance data rates and functionality. The latest version, PCIe 6.0, doubles the data rate to 64 GT/s, enabling up to 256 GB/s of bandwidth in an x16 configuration. The technology incorporates PAM4 signaling and forward error correction to maintain high speeds with improved signal integrity and reliability. PCIe 6 presents significant design and verification challenges due to its strict specifications and narrow margins for the physical layer and interfaces.

 

High speeds and dense circuitry increase the risk of cross talk, jitter, noise, and channel loss, potentially impairing PCIe link performance. Designers must implement robust strategies and tools to overcome these issues to guarantee the compliance and interoperability of PCIe 6 devices and systems.

 

This white paper examines the benefits and challenges of PCIe 6 for high-speed digital designs and outlines solutions using advanced simulation and virtual prototyping tools.
