Simulation Replay Tackles Key Verification Challenges


Simulation lies at the heart of both verification and pre-silicon validation for every semiconductor development project. Finding functional or power problems in the bringup lab is much too late, leading to very expensive chip turns. Thorough simulation before tapeout, coupled with comprehensive coverage metrics, is the only way to avoid surprises in silicon. However, the enormous size and comp... » read more

eFuses: Use Cases, Benefits, And Design In The System Context


In recent years, the automotive industry has been one of the drivers of innovation in the field of electrical and electronic system safety. This is primarily due to the rapid uptake and, in some cases, already mandatory use of advanced driver assistance systems (ADAS) as well as to the first steps toward (partially) autonomous vehicles. In conventional safety systems, the off state can be as... » read more

Can You Rely Upon Your NPU Vendor To Be Your Customers’ Data Science Team?


The biggest mistake a chip design team can make in evaluating AI acceleration options for a new SoC is to rely entirely upon spreadsheets of performance numbers from the NPU vendor without going through the exercise of porting one or more new machine learning networks themselves using the vendor toolsets. Why is this a huge red flag? Most NPU vendors tell prospective customers that (1) the v... » read more

HBM4 Feeds Generative AI’s Hunger For More Memory Bandwidth


Generative AI (Gen AI), built on the exponential growth of Large Language Models (LLMs) and their kin, is one of today’s biggest drivers of computing technology. Leading-edge LLMs now exceed a trillion parameters and offer multimodal capabilities so they can take a broad range of inputs, whether they’re in the form of text, speech, images, video, code, and more, and generate an equally broa... » read more

Is PPA Relevant Today?


The optimization of power, performance, and area (PPA) has been at the core of chip design since the dawn of EDA, but these metrics are becoming less valuable without the context of how and where these chips will be used. Unlike in the past, however, that context now comes from factors outside of hardware development. And while PPA still serves as a useful proxy for many parts of the hardwar... » read more

DDR5 12.8Gbps MRDIMM IP: Powering The Future Of AI, HPC, And Data Centers


The demand for higher-performance computing is greater than ever. Cutting-edge applications in artificial intelligence (AI), big data analytics, and databases require high-speed memory systems to handle the ever-increasing volumes and complexities of data. Advancements in cloud computing and machine virtualization are stretching the limits of current capabilities. AI applications hosted in the ... » read more

Higher Density, More Data Create New Bottlenecks In AI Chips


Data movement is becoming a bigger problem at advanced nodes and in advanced packaging due to denser circuitry, more physical effects that can affect the integrity of signals or the devices themselves, and a significant increase in data from AI and machine learning. Just shrinking features in a design is no longer sufficient, given the scaling mismatch between SRAM-based L1 cache and digital... » read more

Understanding The Total Cost Of Ownership In HPC And AI Systems


Cost is often the deciding factor when it comes to purchasing decisions at an organization, particularly those dealing with high-tech investments. When organizations evaluate proposals for new procurements, the initial capital cost of the system often receives significant attention. A great deal of preparation and planning goes into the decision to make a large purchase. While this is a critica... » read more

On Analysis Of RDC Issues For Identifying Reset Tree Design Bugs And Further Strategies For Noise Reduction


Reset tree checks should be viewed thoroughly before reset domain crossing analysis. Static verification tools have many checks for reset tree analysis. This paper discusses the usage of non-resettable registers (NRRs) in reset paths. NRRs can cause metastability in the reset paths and hence thorough verification is a must. The paper discusses reduction of false failure reporting noise strategi... » read more

The Challenges Of Upgrading Lithium Batteries


The ongoing electrification of everyday items has resulted in the proliferation of batteries, and spurred continued development for automotive and grid use. Lithium-ion batteries still dominate the rechargeable-battery landscape, with solid-state versions prolonging that position, but other lithium variants aim for greater safety while raising energy capacity. Battery researchers must balanc... » read more
