Week In Review: Design, Low Power


Xilinx filed a patent infringement countersuit against Analog Devices, alleging infringement of eight U.S. patents including technologies involving serializers/deserializers (SerDes), high-speed ADCs and DACs, as well as mixed-signal devices targeting 5G and other markets. The counterclaims are in response to Analog Devices' December lawsuit alleging unauthorized use by Xilinx of eight ADI pate... » read more

Electromagnetic Challenges In High-Speed Designs


ANSYS’ Anand Raman, senior director, and Nermin Selimovic, product sales specialist, talk with Semiconductor Engineering about how to deal with rising complexity and tighter tolerances in AI, 5G, high-speed SerDes and other chips developed at the latest process nodes where the emphasis is on high performance and low power. » read more

Die-To-Die Connectivity


Manmeet Walia, senior product marketing manager at Synopsys, talks with Semiconductor Engineering about how die-to-die communication is changing as Moore’s Law slows down, new use cases such as high-performance computing, AI SoCs, optical modules, and where the tradeoffs are for different applications.   Interested in more Semiconductor Engineering videos?

Speeding Up 3D Design


2.5D and 3D designs have garnered a lot of attention recently, but when should these solutions be considered and what are the dangers associated with them? Each new packaging option trades off one set of constraints and problems for a different set, and in some cases the gains may not be worth it. For other applications, they have no choice. The tooling in place today makes it possible to de... » read more

Accelerating Chiplets With 112G XSR SerDes PHYs


The fading of Moore’s Law and an almost exponential increase in data is challenging the semiconductor industry as never before. Indeed, zettabytes of data are constantly generated by a wide range of devices including IoT endpoints such as vehicles, wearables, smartphones and appliances. Moreover, sophisticated artificial intelligence (AI) and machine learning (ML) applications are adding new ... » read more

Long And Longer Reach SerDes – On The Road Again


We’ve had the pleasure of participating in two events over the past two weeks. I wouldn’t recommend doing two major shows back-to-back, but it has been exhilarating and quite interesting. Our “road trip” began last week in Mountain View for the second annual AI Hardware Summit. You’ve probably noticed you can go to an AI-related show every week (or more) if you like. The trick is to f... » read more

Nvidia’s Top Technologists Discuss The Future Of GPUs


Semiconductor Engineering sat down to discuss the role of the GPU in artificial intelligence, autonomous and assisted driving, advanced packaging and heterogeneous architectures with Bill Dally, Nvidia’s chief scientist, and Jonah Alben, senior vice president of Nvidia’s GPU engineering, at IEEE’s Hot Chips 2019 conference. What follows are excerpts of that conversation. SE: There are ... » read more

OIF Eyes Expanded Electrical Link Definitions For 112 Gbps


The insatiable demand for more bandwidth, lower latencies, and higher speeds is driven by a diverse range of applications and use cases. These include artificial intelligence /machine learning, sophisticated ADAS systems for semi-autonomous vehicles, 4K-8K video streaming, eSports, and AR/VR. With global IP traffic now measured in zettabytes (ZB) per year, hyperscalers and service providers ... » read more

Meeting The Demands Of PAM4 Systems At 56Gbps And Beyond


According to an IDC white paper sponsored by Seagate the global datasphere will grow from 33 zettabytes (one zettabye = one trillion gigabytes) in 2018 to 175 zettabytes by 2025. This white paper also reports that today, more than 5 billion consumers interact with data every day. By 2025, that number will be 6 billion, or 75 percent of the world’s population. Figure 1 depicts this exponential... » read more

Advanced Features Of High Speed Digital I/O Devices: Double Data Rate


As clock speeds and data rates continue to increase, designers of digital integrated circuits are creating new ways to maximize the rate of data being sent into and out of digital devices. One such method is known as double data rate (DDR). With single data rate (SDR) devices, data is latched on either the rising or falling edges of the sample clock. A DDR device latches data on both the rising... » read more
