As technology continues to evolve at a rapid pace, the importance of robust and efficient interconnect standards cannot be overstated. Peripheral Component Interconnect Express (PCIe) has been a cornerstone in high-speed data transfer, enabling seamless communication between various hardware components.   

With the advent of PCIe 6.1 ECN, a significant advancement in speed and efficiency, ensuring the accuracy and reliability of its operations is paramount. One critical aspect of this is the verification of shared credit updates. For detailed understanding on Shared Credit, please refer Understanding PCIe 6.0 Shared Flow Control. 

In this blog, we will discuss why this verification is essential and what it entails.  

Introduction 

PCIe 6.1 ECN brings numerous advancements over earlier versions, such as increased bandwidth and faster data transfer speeds.   

A crucial mechanism for efficient data transmission in PCIe 6.0 is the credit-based flow control system. In this system, devices monitor credits, representing the buffer capacity available for incoming data.   

When a device transmits data, it uses credits, which are replenished or adjusted once the data is received and processed. This system ensures that the sender does not overload the receiver.  

Given the critical role of shared credit updates in maintaining the integrity and efficiency of data transfers, verification of these updates is crucial.  Proper management of credit updates is essential to ensure data integrity, as any discrepancies can lead to data loss, corruption, or system crashes.   

Verification also guarantees efficient resource allocation, preventing scenarios where some components are starved of credit while others have an excess, thus avoiding inefficiencies.  Credit inefficiencies pose issues in low power negotiations by preventing devices from entering low power states. Additionally, verification involves checking for proper error handling mechanisms, ensuring that the system can recover gracefully from errors in credit updates and maintain overall stability.   

PCIe 6.1 ECN Flow Control Optimizations Over PCIe 6.0

PCIe 6.1 ECN builds on the FLIT-based architecture introduced in PCIe 6.0, further optimizing flow control mechanisms to handle increased data rates and improved efficiency.  PCIe 6.1 ECN introduced refinements in credit management, making the allocation and advertisement of credits more precise, which helps in reducing bottlenecks and improving data flow efficiency.  Enhancements in flow control protocols ensure better management of buffer spaces and more efficient credit allocation. These enhancements are designed to handle the increased data rates and throughput demands of next-generation applications, ensuring robust and efficient data flow across PCIe devices.  

Below are some major updates: 

1. There have been improvements in error detection and correction mechanisms in PCIe 6.1 ECN to enhance flow control reliability by ensuring that corrupted data packets are detected and handled appropriately without disrupting the flow of valid packets.  
2. The merged credit system, which was a key feature introduced int PCIe 6.0 to simplify and optimize credit management, was further enhanced in PCIe 6.1 ECN to improve performance and efficiency.  
3. PCIe 6.1 ECN introduced better algorithms for allocating and reclaiming merged credits to handle high data rates, introduced more robust error detection and correction mechanism reducing the degradation or system instability. 
4. PCIe 6.1 ECN provided clear guidelines on how to implement the merged credit system correctly, helping developers to implement more reliable systems. For more details, please refer to Specifications section 2.6.1 Flow Control (FC) Rules.

Summary 

In summary, PCIe 6.0 is a complex protocol with many verification challenges. You must understand many new Spec changes and think about the robust verification plan for the new features and backward compatible tests impacted by new features. Cadence’s PCIe 6.0 Verification IP is fully compliant with the latest PCIe Express 6.0 specifications and provides an effective and efficient way to verify the components interfacing with the PCIe 6.0 interface. Cadence VIP for PCIe 6.0 provides exhaustive verification of PCIe-based IP and SoCs, and we are working with early adopter customers to speed up every verification stage.

In the era of Artificial Intelligence, front-end designers need a magical key to empower them with technology that enables fully optimized RTL for implementation handoff and provides RTL designers with capabilities to accurately assist in the implementation convergence process.

The magic lies with Cadence Joules RTL Design Studio, an expert system that leverages generative AI for RTL design exploration, triages possible causes of violations, and additional insights that empower designers to understand how to address issues in their RTL, leading to smarter and more efficient chip design.

This unlocks the immense debugging and design analysis capabilities from a single, unified cockpit, enabling fully optimized RTL design prior to implementation handoff for the front-end designers and addresses all aspects of physical design by adding visibility into power, performance, area, and congestion (PPAC)

One critical component is the clock tree, which distributes the clock signal to all sequential elements, such as flip-flops and latches. Designers need the right techniques in the beginning stage to optimize the clock tree structure, ensuring that their designs meet the required timing specifications, reduce power consumption, maintain signal integrity, and increase reliability.

 This incredible feature is part of the Joules RTL Design Studio.

How do you efficiently explore the clock tree structure to optimize the results using Joules RTL Design Studio?

Joules Studio allows viewing a simplified version of the clock structure. This feature is primarily designed to help display clock frequency scaling through clock dividers. You can customize colors, symbols, and design elements using an input file. Additionally, you can cross-probe the custom clock tree structure to other widgets and the main schematic view in Joules Studio.

Moreover, with the clock tree preference features of the ideal clock tree wizard in Joules Studio GUI, you can highlight clock path, generate clocks and master clock, set case analysis, fold and unfold instances, undo and redo, set sense and disable timing, color preference, etc.

You can binge on these features through the channel videos posted on the support portal, which covers the Joules RTL Design Studio GUI Clock Tree Structure and Features of Ideal Clock Tree Wizard.

You can refer to the videos on Cadence Online Support (Cadence login required).

Some days, I wonder if every word written before a trailer is actually superfluous. It’s a visual medium, after all. What can a description achieve save to clumsily gesture at the true shape of something; a dog-eared tour brochure for a thrilling weekend spelunking in Plato’s cave? I can usually shake this feeling, but gory zombie action game Showa American Story is my breaking point. There is nothing I can impart about this thing that will not be conveyed better by allowing its new trailer to wash over you like a tide of sheer videogame. Here’s it:
