DDR5 UDIMM Evolution To Clock Buffered DIMMs (CUDIMM)


DDR5 is the latest generation of PCDDR memory that is used in a wide range of application like data centers, Laptops and personal computers, autonomous driving systems, servers, cloud computing, and gaming are now increasingly being used for AI applications with advances in memory bandwidth and density to allow DDR5 DIMMs (Dual Inline Memory Modules) to support densities higher then 256 GB per ... » read more

RAG-Enabled AI Stops Hallucinations, Adds Sources


Many EDA companies have taken the first steps to incorporate generative AI into their tools, and in such tightly controlled environments GenAI appears to have great benefits. But its broader adoption has been delayed by its notorious inaccuracy, giving results that are often out of date, untrue, and unsourced. That's starting to change. GenAI is evolving so rapidly that these kinds of proble... » read more

Signal Integrity Basics


In this orientation to signal integrity basics, we aim to introduce several important and fundamental concepts of signal integrity for the beginner. Most explanations are provided at a high level without a lot of depth and math, and examples are provided with a focus on comparison rather than detailed numerical results. Of course, background depth, math, and numerical details are very important... » read more

Pressure Builds To Adopt Virtual Prototypes


Virtual prototypes, often used as a niche tool in the past, are becoming essential for developing complex systems. In fact, systems companies are finding they no longer can function without them. In the semiconductor industry, a virtual prototype is a model for a system at an abstraction level above RTL. But there is no such thing as 'the' virtual prototype. They are constructed for a partic... » read more

Method To Determine The Permittivity of Dielectric Materials in 3D Integrated Structures At Broadband RF Frequencies


A new technical paper titled "Characterizing the Broadband RF Permittivity of 3D-Integrated Layers in a Glass Wafer Stack from 100 MHz to 30 GHz" was published by researchers at NIST. Abstract "We present a method for accurately determining the permittivity of dielectric materials in 3D integrated structures at broadband RF frequencies. With applications of microwave and millimeter-wave ele... » read more

Formal Verification Of A Mixed Signal IP with Both Digital And Analog Blocks


A new technical paper titled "Analogous Alignments: Digital "Formally" meets Analog" was published by researchers at Infineon Technologies. Abstract: "The complexity of modern-day System-on-Chips (SoCs) is continually increasing, and it becomes increasingly challenging to deliver dependable and credible chips in a short time-to-market. Especially, in the case of test chips, where the aim is... » read more

Maximizing Coverage Metrics with Formal Unreachability Analysis


Coverage lies at the very heart of functional verification. Whether designing a single intellectual property (IP) block or a huge system on chip (SoC), verification teams need to know how well the design has been tested. Functional coverage, code coverage, toggle coverage, assertion coverage, and other metrics are widely used. Improving tests to fill in coverage holes is a key part of the proce... » read more

Devising Security Solutions For Hardware Threats


Experts At The Table: Hardware security has evolved considerably in recent years, but getting products to market is a challenge in an environment where threats are always evolving and rarely predictable. That’s especially true given the sheer volume and variety of products being introduced. Semiconductor Engineering sat down with a panel of experts at the Design Automation Conference in San F... » read more

Impact of Finite Interconnect Impedance Including Spatial and Domain Comparison of PDN Characterization


Abstract Over the past few decades, a lot of details have been worked out in power distribution network design, simulation and measurement. We have well-established PDN design procedures both in the frequency and time domains, we have simulation tools that can analyze the physical structure from DC to very high frequencies, including spatial variations of the behavior, and we also have fre... » read more

UMI Can Scale the Memory Wall


While the improvements in processor performance to enable the incredible compute requirements of applications like Chat-GPT get all the headlines, a not-so-new phenomenon known as the memory wall risks negating those advancements. Indeed, it has been clearly demonstrated that as CPU/GPU performance increases, wait time for memory also increases, preventing full utilization of the processors. ... » read more
