Designing Resilient Electronics


Electronic systems in automobiles, airplanes and other industrial applications are becoming increasingly sophisticated and complex, required to perform an expanding list of functions while also becoming smaller and lighter. As a result, pressure is growing to design extremely high-performance chips with lower energy consumption and less sensitivity to harsh environmental conditions. If this ... » read more

HBM Issues In AI Systems


All systems face limitations, and as one limitation is removed, another is revealed that had remained hidden. It is highly likely that this game of Whac-A-Mole will play out in AI systems that employ high-bandwidth memory (HBM). Most systems are limited by memory bandwidth. Compute systems in general have maintained an increase in memory interface performance that barely matches the gains in... » read more

Improving Circuit Reliability


Carey Robertson, product marketing director at Mentor, a Siemens Business, examines reliability at advanced and mainstream nodes, particularly in automotive and industrial applications, what’s driving growing concern about the reliability and fidelity of analog circuits, and the impact of running circuits for longer periods of time under different voltage and environmental conditions. » read more

Where Timing And Voltage Intersect


João Geada, chief technologist at ANSYS, talks about the limitations for power delivery networks and what processors can handle, why the current solutions to these issues are causing failures, and how voltage reduction can affect timing. » read more

Analog: Avoid Or Embrace?


We live in an analog world, but digital processing has proven quicker, cheaper and easier. Moving digital data around is only possible while the physics of wires can be safely abstracted away enough to provide reliable communications. As soon as a signal passes off-chip, the analog domain reasserts control for modern systems. Each of those transitions requires a data converter. The usage ... » 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

Migrating 3D Into The Mainstream


Semiconductor Engineering sat down to discuss changes required throughout the ecosystem to support three-dimensional (3D) chip design with Norman Chang, chief technologist for ANSYS' Semiconductor Business Unit; John Park, product management director for IC packaging and cross-platform solutions at Cadence; John Ferguson, director of marketing for DRC applications at Mentor, a Siemens Business;... » read more

Thermal Challenges And Moore’s Law


Steven Woo, fellow and distinguished inventor at Rambus, looks at the evolution of graphics cards over a couple of decades and how designs changed to deal with more graphics and more heat, and why smaller, faster and cheaper doesn’t apply in this market. » read more

Automation And Correct By Construction Will Empower 3D-IC Adoption


When research on 3D ICs was in full swing around 2009, I had been researching on how through-silicon-via (TSV) was related to thermal in a semiconductor chip-making company, and it seemed logical that 3D ICs would become mainstream. However, during the past 10 years, use of 3D stacked die has been applied to only a few applications, such as memory or image sensors, and the 2.5D solution using i... » read more

Why Chips Are Getting Noisier


In the past, designers only had to worry about noise for sensitive analog portions of a design. Digital circuitry was immune. But while noise gets worse at newer process nodes, staying at 28nm does not mean that it can be ignored anymore. With Moore's Law slowing, designs have to do more with less. Margins are being squeezed, additional concurrency is added, and attempts are made to opti... » read more
