Week In Review: Design, Low Power


Intellectual Property Flex Logix inked an agreement with the Air Force Research Laboratory, Sensors Directorate (AFRL/RY) covering any Flex Logix IP technology for use in all US Government-funded programs for research and prototyping purposes with no license fees. “Our first license with AFRL for EFLX eFPGA in GlobalFoundries 12nm process was highly successful, with more than a half dozen pr... » read more

Week In Review: Auto, Security, Pervasive Computing


Pervasive computing, IoT, 5G and beyond Keysight Technologies received a U.S. Federal Communications Commission (FCC) Spectrum Horizons Experimental License to develop 6G technology in sub-terahertz, between 95 gigahertz (GHz) and 3 THz. "Innovations in sub-THz spectrum will support use-cases such as immersive telepresence, digital twins and extended reality, which is all real-and-virtual comb... » read more

Power Now First-Order Concern In More Markets


Concerns about energy and power efficiency are becoming as important as performance in markets where traditionally there has been a significant gap, setting the stage for significant shifts in both chip architectures and in how those ICs are designed in the first place. This shift can be seen in a growing number of applications and vertical segments. It includes mobile devices, where batteri... » read more

Why Comparing Processors Is So Difficult


Every new processor claims to be the fastest, the cheapest, or the most power frugal, but how those claims are measured and the supporting information can range from very useful to irrelevant. The chip industry is struggling far more than in the past to provide informative metrics. Twenty years ago, it was relatively easy to measure processor performance. It was a combination of the rate at ... » read more

Accelerating Circuit Simulation 10x With GPUs


By Samad Parekh (Synopsys) and Srinivas Kodiyalam (NVIDIA) Many aspects of semiconductor design and verification have an ever-growing “need for speed” that has outpaced the performance improvements available by running on CPUs. Electronic design automation (EDA) companies have responded by creating smarter software algorithms to improve simulation time, sometimes at the expense of relaxe... » read more

Blog Review: March 9


Arm's Ajay Joshi investigates how to select the right benchmark for CPUs used in the Home device market, such as digital television and set-top box/over-the-top devices. Ansys' Jon Kordell checks out how reliability physics simulations and physical component characterization can support component swapping in high-reliability applications when the original part is unavailable due to supply ch... » read more

Software-Driven and System-Level Tests Drive Chip Quality


Traditional semiconductor testing typically involves tests executed by automatic test equipment (ATE). But engineers are beginning to favor an additional late-test pass that tests systems-on-chip (SoCs) in a system context in order to catch design issues prior to end-product assembly. “System-level test (SLT) gives a high-volume environment where you can test the hardware and software toge... » read more

A Practical Approach To DFT For Large SoCs And AI Architectures, Part II


By Rahul Singhal and Giri Podichetty Part I of this article discusses the design-for-test (DFT) challenges of AI designs and strategies to address them at the die level. This part focuses on the test requirements of AI chips that integrate multiple dies and memories on the same package. Why 2.5D/3D chiplet-based designs for AI SoCs? Many semiconductor companies are adopting chiplet-based d... » read more

Auto Chipmakers Dig Down To 10ppb


How do engineers deliver 10 defective parts per billion (Dppb) to auto makers if they only screen 1 million parts per year? Answer: By comprehending failure mechanisms and proactively screening for them. Modern automobiles contain nearly 1,000 ICs that must perform over the vehicle’s life (15 years). This drives quality expectations ever higher. While 10 Dppm used to be a solid benchmark, ... » read more

Improving Performance And Simplifying Coding With XY Memory’s Implicit Parallelism


Instruction-level Parallelism (ILP) refers to design techniques that enable more than one RISC instruction to be executed simultaneously in the same instruction, which boosts processor performance by increasing the amount of work done in a given time interval, thereby increasing the throughput. This parallelism can be explicit, where each additional instruction is explicitly part of the instruc... » read more
