This White Paper gives engineers a comprehensive overview of how PCI Express testing has evolved from PCIe 3.0 through 6.0 — and why the move to 64 GT/s and PAM4 signaling is reshaping both physical-layer and protocol-layer validation.
What you will learn about:
- How PCI Express has scaled across six generations, from 2.5 GT/s to 64 GT/s and 256 Gb/s of throughput over 16 lanes, while staying backward compatible with earlier revisions.
- Why the shift from NRZ to PAM4 signaling in PCIe 6.0 — with eye heights as small as 6 mV — introduces signal-integrity and measurement challenges that earlier generations did not face.
- What each stage of physical-layer validation involves: pre-layout system simulation, interconnect characterization such as crosstalk, insertion loss and PAM4 eye diagrams, transmitter compliance, and receiver and link-equalization testing.
- How protocol-layer analysis exposes link-training and LTSSM behavior, and why a fully validated PCIe layer underpins higher-layer protocols such as NVMe and CXL.
