PCIe 6.0 Protocol Update

This session covers PCI Express protocol developments over the last year or two, including completed ECNs, selected ECRs under development, and key protocol/spec changes envisioned for PCIe 7.0.  Completed ECNs include Relaxed Detect Timing, TDISP, DOE 1.1, Alternative Protocol DLLP Reservation, and Unordered I/O (UIO).  Selected ECRs under development include Sideband Signals, CMA-SPDM, 12V2x6 Connector Updates, MMIO Mailbox Passthrough (MMPT), OHC-E Capability Enumeration, Inter-System Bridge (ISB), ATS 2.0, and Remote Memory Operations (RMOps). 

PCIe 6.0 PHY Logical

PCI Express (PCIe) specification has been doubling the data rate every generation in a backwards compatible manner every two to three years. PCIe 6.0 specification has adopted PAM-4 signaling at 64.0 GT/s for maintaining the same channel reach as prior generations. A forward error correction (FEC) mechanism will offset the high BER of PAM-4. A new Flit-based approach with a light-weight, low-latency FEC coupled with a strong CRC and a low-latency link level retry mechanism in PCIe 6.0 specification meets the stringent low-latency, high bandwidth and high reliability goals. Shared credit pooling across multiple virtual channels is included to reduce the area and power overhead while providing the necessary quality of service guarantees. We also present a new low-power state (L0p) that ensures power consumption is proportional to bandwidth usage without impacting the traffic flow.

PCIe Electrical Basics

PCIe Electrical Basics will give the audience an overview of the physical layer specification. We will focus our discussion on target channels central to the base electrical spec development, as well as key transmitter and receiver architecture requirements. We will also discuss in depth the channel compliance simulation methodology enabled by Seasim (Statistical Channel Simulator).

PCIe CEM Updates 

This presentation provides updates on the PCI Express CEM specification development work in the PCI-SIG Electromechanical Workgroup. The presentation focuses on providing an overview of the changes introduced in PCI Express Card Electromechanical Specification, Rev 5.0 (CEM 5.0) and related ECRs. The presentation also provides an overview of several potential improvements under investigation for CEM 6.0. This includes Add-in Card outline updates, sideband interfaces and connector optimizations. 

PCIe Compliance Updates

The PCI-SIG has introduced the 5.0 Integrators List program with a new maximum data rate of 32 GT/s enabling a bi-direction link bandwidth up to 128 GB/s for a x16 link. The PCI Express Architecture PHY Test Specification Rev 5.0 has updated the 16 GT/s tests to support the faster rate and introduced new testing requirements including uncorrelated jitter and pulse width jitter for all 5.0 devices. Discussion of measurement methodologies for Tx Signal Quality and Link Equalization testing will provide insight into the latest measurement methodologies.
