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 Electrical Update

In this presentation, we will provide an overview of updates to the specification of Reference Clock, Transmitter, Receiver, and Channel Compliance for PCIe 6.0 64 GT/s data rate. We will highlight the key improvements in circuit and channels required for achieving doubling of the data rate over PCIe 5.0.

PCIe Form-Factor Updates

This presentation provides updates on the PCI Express CEM specification, PCI Express Mini (M.2) specification and PCI Express SFF Connector (U.2) specification development work in respective PCI-SIG workgroups. The presentation focuses on an overview of the changes introduced in Rev 5.0 of the specifications and related ECRs. The presentation will also provide an update on the current workgroup direction for Rev 6.0 Specification development that will add support for 64 GT/s. This includes Add-in Card outline updates, sideband interfaces and connector signal integrity optimizations.

PCI Overview

This session provides a brief overview of the current state of the PCI-SIG.  Topics covered include the current Board of Directors, specification roadmaps, and new workgroups for optical and electrical cabling technologies along with a brief update on expansions of the PCI-SIG compliance program.

PCI Express Basics

In this session, attendees learn the basics of the PCI Express Architecture. This presentation covers the key features of PCI Express and provides an overview of the Electrical, Packet-based Protocol and Configuration Mechanism of this high-performance serial bus architecture. This session is geared towards attendees new to PCI Express Technologies.

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).
