Scenario Solutions

NAND is a non-volatile storage technology known as “Not AND” and is a type of DRAM (Dynamic Random Access Memory) NAND flash memory is preferred for a wide range of applications, from smartphones to data center storage solutions, due to its high storage density, fast read/write speeds, low power consumption, non-volatility, high endurance, cost-effectiveness, compact size, high reliability, and instant-start characteristics. It has become the first choice for a wide range of applications from smartphones to data center storage solutions. These advantages have made NAND flash memory an indispensable storage technology for modern digital devices, which are widely used in consumer electronics, data centers, IoT devices and automotive electronics.

Julin's SIDesigner focuses on signal integrity issues in NAND storage technology, where NAND flash memory is important for storing large amounts of information in both consumer level (automotive, medical devices, computers, cell phones, etc.) and industrial level (5G controllable units, software developers, cloud service providers). During high-speed data transmission, signal integrity is critical to ensure error-free data transfer and storage.

When an electronic device acquires information and stores it in NAND flash memory, a large amount of data needs to be transmitted over a high-speed bus, which can cause signal distortion, attenuation, reflections, and crosstalk, affecting the integrity and accuracy of the data.SIDesigner provides optimized solutions for storage devices that use NAND technology through accurate signal modeling and simulation.

First, SIDesigner analyzes and predicts the signal integrity of NAND flash interfaces, allowing engineers to reduce signal distortion by adjusting topologies, cabling strategies, and selecting appropriate signal conditioning techniques (e.g., pre-emphasis, equalizers, etc.). Secondly, it supports compatibility testing of different NAND memory grades and interface standards (e.g. SPI, eMMC, UFS, etc.) to ensure faithful feedback of accurate signal quality even under high-bandwidth, low-voltage test operations.

In addition, SIDesigner provides detailed topology devices and test scenarios to help engineers build simulation models to identify and resolve potential signal integrity issues, thus ensuring the stability and reliability of NAND storage devices under different operating conditions. With these features, SIDesigner software provides NAND manufacturers with an efficient and comprehensive signal integrity simulation solution.

SIDesigner helps engineers perform accurate signal integrity analysis of NAND flash interfaces early in the design phase to ensure high-speed, low-latency and high-reliability data transmission, and optimize PCB layout and tracing to minimize signal loss and distortion; simulation allows them to anticipate and resolve possible signal integrity issues such as reflections, crosstalk and noise, thus avoiding them before actual production and deployment to reduce rework and maintenance costs. SIDesigner helps designers meet the telecom industry's stringent signal integrity and electromagnetic compatibility (EMC) standards, ensuring product compliance in a variety of application environments; by providing accurate signal integrity simulations, SIDesigner helps reduce the number of design iterations, shorten time-to-market, lower R&D costs, and ensure that products meet the high-quality requirements of telecom service providers; with the increasing demands of telecom service providers, SIDesigner can help reduce the number of design iterations, shorten time-to-market, lower R&D costs and ensure that products meet telecom service providers' high-quality requirements. With growing telecom network capacity, SIDesigner's signal integrity analysis ensures that NAND flash memory will be able to adapt to future big data requirements and support system expansion and upgrades.

AI systems often require fast access to large amounts of data for training and inference. Signal integrity optimization with Julin SIDesigner ensures that NAND flash memory provides data read and write speeds that accelerate the model training and computation process.The data involved in AI applications is often very large and critical, and signal integrity analysis helps to reduce the data error rate and ensure the integrity and consistency of the data, which is critical to the accuracy and performance of AI models. In AI hardware design, reducing power consumption is one of the design goals. By optimizing the signal path, energy loss during transmission can be reduced, enabling more energy-efficient NAND flash operations. System stability is especially important when dealing with complex AI tasks. SIDesigner helps reduce system crashes or performance degradation caused by signaling issues and ensures that AI systems continue to operate. AI hardware often requires the integration of multiple storage and compute components, and SIDesigner provides signal integrity analysis to ensure that NAND works seamlessly with GPUs, CPUs, and other components, improving overall system performance. The rapid evolution of AI technology requires storage solutions that can adapt to growing demands. Signal integrity analysis supports system scalability and future upgrades to handle larger data processing requirements.
