SAS Customer Intelligence 360: Enriching analysis with device usage data was published on Customer Intelligence Blog.

The application of real-time data processing or responsiveness is crucial, such as in high-performance computing, data centers, or applications requiring low-latency data transfers. It enables efficient use of PCIe bandwidth and resources by intelligently managing memory write operations based on system dynamics and workload priorities. By effectively leveraging Deferrable Memory Write [DMWr], Devices can achieve optimized performance and responsiveness, aligning with the evolving demands of modern computing applications.

What Is Deferrable Memory Write?

Deferrable Memory Write (DMWr) ECN introduced this new memory transaction type, which was later officially incorporated in PCIe 5.0 to CXL2.0. This enhanced type of memory transaction is Deferrable Memory Write [DMWr], which flows as another type of existing Read/Write memory transaction; the major difference of this Deferrable Memory Write, where the Requester attempts to write to a given location in Memory Space using the non-posted DMWr TLP Type, it Postponing their completion of memory write transactions to improve overall system efficiency and performance, those memory write operation can be delay or deferred until other priority task complete.

The Deferrable Memory Write (DMWr) requires the Completer to return an acknowledgment to the Requester and provides a mechanism for the recipient to defer (temporarily refuse to service) the Request.

DMWr provides a mechanism for Endpoints and hosts to choose to carry out or defer incoming DMWr Requests. This mechanism can be used by Endpoints and Hosts to simplify the design of flow control, reduce latency, and improve throughput. The Deferrable Memory writes TLP format in Figure A.

(Fig A) Deferrable Memory writes TLP format.

Example Scenario

Here's how the DMWr works with a simplified example: Imagine a system with an endpoint device (Device A) and a host CPU (Device B). Device B wants to write data to Device A's memory, but due to varying reasons such as system bus congestion or prioritization of other transactions, Device A can defer the completion of the memory write request. Just follow these steps:

1. Initiation of Memory Write: Device B initiates a memory write transaction to Device A. This involves sending the memory write request along with the data payload over the PCIe physical layer link.
2. Acknowledgment and Deferral: Upon receiving the memory write request, Device A acknowledges the transaction but may decide to defer its completion. Device A sends an acknowledgment (ACK) back to Device B, indicating it has received the data and intends to complete the write operation but not immediately.
3. Deferred Completion: Device A defers the completion of the memory write operation to a later, more opportune time. This deferral allows Device A to prioritize other transactions or optimize the use of system resources, such as memory bandwidth or processor availability.
4. Completion and Response: At a later point, Device A completes the deferred memory write operation and sends a completion indication back to Device B. This completion typically includes any status updates or additional information related to the transaction.

Usage or Importance of DMWr

Deferrable Memory Write usage provides the improvement in the following aspects:

• Reduced Latency: By deferring less critical memory write operations, more critical transactions can be processed with lower latency, improving overall system responsiveness.
• Improved Efficiency: Optimizes the utilization of system resources such as memory bandwidth and CPU cycles, enhancing the efficiency of data transfers within the PCIe architecture.
• Enhanced Performance: Allows devices to manage and prioritize transactions dynamically, potentially increasing overall system throughput and reducing contention.

Challenges in the Implementation of DMWr Transactions

The implementation of deferrable memory writes (DMWr) introduces several advancements and challenges in terms of usage and verification:

1. Timing and Synchronization: DMWr allows transactions to be deferred, complicating timing requirements or completing them within acceptable timing windows to avoid protocol violations. Ensuring proper synchronization between devices becomes critical to prevent data loss or corruption.
2. Protocol Compliance: Verification must ensure compliance with ECN PCIe 6.0 and CXL specifications regarding when and how DMWr transactions can be initiated and completed.
3. Performance Optimization: While DMWr can improve overall system performance by reducing latency, verifying its impact on system performance and ensuring it meets expected benchmarks is crucial.
4. Error Handling: Handling errors related to deferred transactions adds complexity. Verifying error detection and recovery mechanisms under various scenarios (e.g., timeout during deferral) is essential.

Verification Challenges of DMWr Transactions

The challenges to verifying the DMWr transaction consist of all checks with respect to Function, Timing, Protocol compliance, improvement, Error scenario, and security usage on purpose, as well as Data integrity at the PCIe and CXL.

1. Functional Verification: Verifying the correct implementation of DMWr at both ends of the PCIe link (transmitter and receiver) to ensure proper functionality and adherence to specifications.
2. Timing Verification: Validating timing constraints associated with deferring writes and ensuring transactions are completed within specified windows without violating protocol rules.
3. Protocol Compliance Verification: Checking that DMWr transactions adhere to PCIe and CXL protocol rules, including ordering rules and any restrictions on deferral based on the transaction type.
4. Performance Verification: Assessing the impact of DMWr on overall system performance, including latency reduction and bandwidth utilization, through simulation and testing.
5. Error Scenario Verification: Creating and testing scenarios to verify error handling mechanisms related to DMWr, such as timeouts, retries, and recovery procedures.
6. Security Considerations: Assessing potential security vulnerabilities related to DMWr, such as data integrity risks during deferred transactions or exposure to timing-based attacks.

Major verification challenges and approaches are timing and synchronization verification in the context of implementing deferrable memory writes (DMWr), which is crucial due to the inherent complexities introduced by deferred transactions. Here are the key issues and approaches to address them:

Timing and Synchronization Issues

1. Transaction Completion Timing:
   • Issue: Ensuring deferred transactions are completed within the specified time window without violating protocol timing constraints.
   • Approach: Design an internal timer and checker to model worst-case scenarios where transactions are deferred and verify that they are complete within allowable latency limits. This involves simulating various traffic loads and conditions to assess timing under different scenarios.
2. Ordering and Dependencies:
   • Issue: Verifying that transactions deferred using DMWr maintain the correct ordering and dependencies relative to non-deferred transactions.
   • Approach: Implement test scenarios that include mixed traffic of DMWr and non-DMWr transactions. Verify through simulation or emulation that dependencies and ordering requirements are correctly maintained across the PCIe link.
3. Interrupt Handling and Response Times:
   • Issue: Verify the handling of interrupts and ensure timely responses from devices involved in DMWr transactions.
   • Approach: Implement test cases that simulate interrupt generation during DMWr transactions. Measure and verify the response times to interrupts to ensure they meet system latency requirements.

In conclusion, while deferrable memory writes in PCIe and CXL offer significant performance benefits, their implementation and verification present several challenges related to timing, protocol compliance, performance optimization, and error handling. Addressing these challenges requires rigorous testing and testbench of traffic, advanced verification methodologies, and a thorough understanding of PCIe specifications and also the motivation behind introducing this Deferrable Write is effectively used in the CXL further. Outcomes of Deferrable Memory Write verify that the performance benefits of DMWr (reduced latency, improved throughput) are achieved without compromising timing integrity or violating protocol specifications.

In summary, PCIe and CXL are complex protocols with many verification challenges. You must understand many new Spec changes and consider the robust verification plan for the new features and backward compatible tests impacted by new features.

Hi,

reading Verilog®-A Language Reference I found this description of ddt function I don't understand:

Use the time derivative operator to calculate the time derivative of an argument.

ddt( input [ , abstol | nature ] )

input is a dynamic expression.

abstol is a constant specifying the absolute tolerance that applies to the output of the ddt operator. Set abstol at the largest signal level that you consider negligible.

nature is a nature from which the absolute tolerance is to be derived.

Can anyone explain how abstol and nature are defined? how using them? an example would be really appreciated.

Thanks

Andrea

Australian food and beverages wowed the crowd at the 2022 Private Label Trade Show in Chicago.

MANILA, Philippines — A new typhoon barreled across an agricultural region in the northeastern Philippines on Monday after thousands were evacuated to safety while still struggling to recover from the devastation caused by three successive storms in the last three weeks. Typhoon Toraji slammed into northeastern Aurora province and was forecast to blow over the mountainous Luzon region, where President Ferdinand Marcos Jr. — just the day before — inspected the damage from the last storm and led the distribution of food packs to residents in Cagayan and Ilocos provinces. Marcos skipped this week's Asia-Pacific Cooperation forum in Peru to oversee recovery efforts from back-to-back storms. After making landfall in Aurora on Monday morning with sustained winds of up to 130 kilometers (81 miles) per hour and gusts of up to 180 kph (112 mph), the typhoon was expected to barrel northwestward across Luzon, weaken as it crosses a mountain range and then blow into the South China Sea. Interior Secretary Jonvic Remulla on Sunday ordered the forcible evacuation of people in 2,500 villages expected to be lashed by Toraji, locally named Nika, warning that the rain-soaked Luzon mountains, valleys and plains were more susceptible to flash floods and landslides. With the typhoon approaching fast, there was little time to move large numbers of people to safety, he said. "We understand if some would want to stay, but we have to get them out," Remulla told reporters. The military said its disaster-response forces have been deployed near high-risk areas and were standing by for new contingencies. It added that it suspended combat drills in the north due to the weather. "Our commitment remains steadfast in safeguarding and assisting our countrymen specially in times of disaster," Armed Forces of the Philippines spokesperson Col. Francel Margareth Padilla said. Schools were shut down, inter-island ferry services and domestic flights were suspended in provinces in or near the path of the typhoon, the 14th weather disturbance to batter the Philippine archipelago this year. Forecasters said they were monitoring another brewing storm in the Pacific that could affect the country if it strengthens. The last two typhoons and a tropical storm caused more than 160 deaths, damaged thousands of houses and farmlands and affected more than 9 million people, including hundreds of thousands who fled to emergency shelters, after dumping from one to two months' worth of rain in just 24 hours in some cities and towns. Overwhelmed, the Philippines received help from Southeast Asian countries led by Singapore, along with longtime treaty ally the United States, to transport food, water and other aid to hard-hit northern provinces. The Philippine archipelago is often battered by typhoons and earthquakes and has more than a dozen active volcanoes, making it one of the most natural disaster-prone countries in the world. In 2013, Typhoon Haiyan, one of the strongest recorded tropical cyclones, left more than 7,300 people dead or missing, flattened entire villages and caused ships to run aground and smash into houses in the central Philippines.

The Pakistan Cricket Board (PCB) said on Tuesday it has asked the sport’s governing body to explain India’s refusal to send a team to Pakistan for the Champions Trophy next year.

The International Cricket Council (ICC) informed the PCB last week that India would not tour Pakistan for the eight-team tournament, leaving the fate of the event hanging in the balance.

Pakistan had previously rejected the option of a hybrid arrangement that would allow India to play their matches at neutral venues, for example in the United Arab Emirates.

“The PCB has responded to last week’s ICC letter seeking clarifications for the Indian Board’s decision not to travel to Pakistan for next year’s Champions Trophy,” Sami-Ul-Hasan told AFP.

Deteriorating political ties have meant the bitter rivals have not played a bilateral cricket series for over a decade — squaring off only in ICC multi-nation events.

Pakistani media reported on Tuesday that the PCB would be unwilling to accept security reasons for India’s refusal to visit.

New Zealand have toured Pakistan three times in the past two years, with England visiting twice and Australia once in the same period.

Pakistan also visited India for last year’s ODI World Cup and the PCB had expected the gesture to be reciprocated for the Champions Trophy.

The Champions Trophy is slated to be played across three venues — Lahore, Rawalpindi and Karachi — from February 19 to March 9 next year.

But a final schedule due to be announced this week has been postponed over the stand-off — which PCB chairman Mohsin Naqvi termed disappointing.

“Almost every country wants the tournament to be played in Pakistan and it will be disappointing if they don’t come,” Naqvi, who is also the interior minister, said last week.

“I don’t think anyone should make this a political matter. We’ll give every team as many facilities as we can.” Naqvi said Pakistan would consider pulling out of events in India as a response.

“Pakistan has shown great gestures to India in the past, and we’d like to say clearly India shouldn’t expect such friendly gestures from us every time”.

India is due to host the women’s ODI World Cup and Asia Cup next year and will co-host the Twenty20 World Cup with Sri Lanka in 2026.
