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 major protocol/spec changes in PCIe 6.0.  Completed ECNs include Combined Power and Relaxed Detect Timing.  Selected ECRs under development include TEE Device Interface Security Protocol (TDISP), DOE 1.1, CMA Update, ATS 2.0, and Unordered I/O (UIO).  Major protocol/spec changes for PCIe 6.0 include Flit Mode, Segment Support in Flit Mode, L0p replacing L0s in Flit Mode, Shared Flow Control Credits, 14-Bit Tags in Flit Mode, Max_Payload_Size enhancements, Deprecated features, and Improved SR-IOV spec integration.

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.

PCI Express Protocol Compliance Troubleshooting and Debug

This presentation discusses the requirements for PCI Express 4.0 and 5.0 Protocol compliance and how to debug and investigate issues that commonly arise during testing. Every component of PCIe Protocol compliance is discussed including Link and Transaction Layer, Retimer Logical, Lane Margining, and Configuration testing. Protocol Testing covers many different areas of the specification but many common issues can be resolved by paying attention to certain key areas prior to testing at a Compliance Workshop, helping to avoid delays in getting the device included on the Integrators List.

Connector and Cable Assembly Challenges for PCIe 5.0 and 6.0

With 32 GT/s in PCIe 5.0 and 64 GT/s in PCIe 6.0, channel characteristics like loss, reflections and crosstalk are increasingly critical for the overall system performance. We will discuss performance requirements and implementations of PCIe 5.0 / 6.0 connectors and cable assemblies and the corresponding test setups and measurement methods to characterize and verify these interconnects. New metrics of ICN and IRL are included, as well as the related measurements. As the PCIe specifications define the performance requirements without the test fixtures, optimized test fixture design and accurate test fixture modelling and de-embedding is key for good measurement results. We will preview modern de-embedding techniques with accurate impedance modelling of lead-ins and lead-outs.

Data Driven Insights Into Stressed Eye Solution Space

The PCI Express Physical Layer Electrical testing requires testing receiver performance using a worst-case transmitter and channel. Establishing this "Stressed Eye Signal" involves a complex calibration procedure quantified with an eye diagram measurement using the latest DSP techniques. The final step in this calibration starts with nominal stress levels and requires adjustment of cross talk, modeled with Differential Mode Interference or DMI, and Sinusoidal Jitter (SJ) to fine tune the eye within a tight tolerance. Legacy data rates have relied on DMI and SJ to impact the vertical and horizontal eye closure respectively. New interactions and dependencies at 32 GT/s have led to a pronounced interdependence impacting the methods used to achieve this signal. This presentation will analyze empirical data to provide insight into the shape of the solution space and guidance for future development at 64 GT/s.

Efficacious Verification of Flit Error Injection in PCIe 6.0​

Nowadays serial protocols have evolved to get the fastest and fittest throughput. This evolution increases the complexity in any serial protocol’s physical Layer. PCIe 6.0 (64 GTs) has many important features added compared to 5.0. One of them is addition if FLIT concept. Also, they have added Flit Error Injection capability. This capability gives user to introduce error in their transmitted Flit or OS. Because of this they can easily verify or achieve some of the corner cases. So, it becomes important to verify this Flit error injection capability. This presentation talks about the efficacious verification of Flit Error Injection Capability. With the verification approach presented in presentation DUT can be tested vigorously by using CDV (constraint random verification). With approach presented in the presentation many issues were discovered. With the said approach we can reduce the verification time and effort. We also achieved 100% function coverage for the same.

PCI Express Basics & Background 

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. 

Designing for Effective Use of PCIe 6.0 Bandwidth

PCI Express 6.0 introduced 64GT/s signaling, bringing maximum PCIe bandwidth up to 256GB/s!  The sheer amount of data movement now possible offers architectural challenges beyond those arising “simply” from the doubling of clock speed or datapath width.  This presentation will discuss design choices and practices needed to make full use of that bandwidth across a variety of design points from x1 to x16 for both Endpoint and Root Port designs.  Various potential pitfalls and performance scenarios will be covered and data presented from actual early implementations. This presentation should be of interest to both experienced and new PCI Express designers.
