This document summarizes the challenges of validating next-generation high-speed interface standards like PCIe 4.0 16Gb/s, USB 10Gb/s, DDR4 3200MT/s, and SAS 12Gb/s. It discusses how the increasing data rates and complex signaling of these interfaces require more advanced compliance and debug tools that can analyze issues like jitter, crosstalk, and channel effects. It provides an overview of several tools from Tektronix that can help with validating the electrical signaling and protocol behavior of these new high-speed buses.
