PCIe Retimer Telemetry for RAS on Cloud Compute Systems

PCIe is a major interconnect between processors, accelerators, networking, and storage components in hyperscale cloud datacenter systems. The ability to monitor, identify, and fix problems with minimal effect on the end user becomes more and more essential as the speed and number of PCIe links increase. PCIe Retimers are uniquely positioned between Root Complex and Endpoint devices and can thus offer telemetry capabilities to monitor and identify potential failures during system activity.

Attendees will:

• Learn how PCIe Retimers can help identify Link reliability issues at cloud scale.

• Understand which kind of parameters a Retimer can extract from the PCIe Link and interconnect.

• Discover why time stamping is important, and how time stamps are captured.

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.

Traffic Generation and Trace Analysis of Select PCIe Features

Traffic generation and trace analysis tools can be used to test, validate, and verify operation of PCI Express traffic, highlighting through a selection of PCI express features: Lane margining, data encryption, power management and error messaging. LM command and margin adjustment packets are generated by either configuration transactions or control skips and decoded into LM transactions, and LM requests and responses are collapsed into LM commands. We illustrate IDE Streams established, IDE TLP prefixes added and associated with an IDE Stream, IDE messages sent, and SPDM key management transport protocols implemented. Low power states – We show how low power entry timeout, and T_power_on and T_common mode exit latency measurement. Error messaging tests – we illustrate how errors can be enabled, masked, their severity set, and non-fatal uncorrectable errors reported as advisory correctable errors.

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.

Troubleshooting Complex LTSSM Corner Cases & Timing

As we move to PCIe 6.0, increased data rates will present even greater interoperability challenges when bringing up links, especially where speed and timing are concerned. During link initiation, link partners follow a complex link training protocol called LTSSM. The protocol includes multiple branching state machines and tight timing constraints. When LTSSM interop issues arise, it can be difficult to replicate them among a myriad of potential causes. This session will provide designers with insight and techniques on troubleshooting these complex transactions with repeatability, including debugging during bringup, and testing boundary conditions with a highly configurable link partner.

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.
