Smaller Nodes, Much Bigger Problems
By Ed Sperling - 15 Jul, 2020 - Comments: 3

João Geada, chief technologist at Ansys, sat down with Semiconductor Engineering to talk about device scaling, advanced packaging, increasing complexity and the growing role of AI. What follows are excerpts of that conversation. SE: We've been pushing along Moore's Law for roughly a half-century. What sorts of problems are you seeing now that you didn't see a couple nodes ago? Geada: The... » read more

Taking Inductance And Electromagnetic Effects More Seriously
By Magdy Abadir - 03 Aug, 2018 - Comments: 0

By Magdy Abadir and Yehea Ismail With increasing frequencies, tighter margins, denser integrated circuits, new devices and materials, the necessity of full EM analysis including magnetic/inductive effects is becoming a fundamental question for the industry. Where and when should full EM verification be included? Can some of major chip failures during development be attributed to ignoring ... » read more

Is It Time To Take Inductance And Electromagnetic Effects On SoCs Seriously?
By Magdy Abadir - 14 Jun, 2018 - Comments: 0

Electromagnetic (EM) crosstalk impact on SoC performance has been a topic of discussion for a number of years, but how seriously have designers put EM crosstalk detection and avoidance into their SoC design practice? With increasing demand for faster bandwidth, lower power and higher density electronic systems, isn’t it about time to take inductance and EM effects seriously? This topic will b... » read more

Electromagnetic Crosstalk Considerations In Low Power Designs
By Magdy Abadir - 19 May, 2018 - Comments: 0

By Magdy Abadir, Padelis Papadopoulos, and Yehea Ismail
 Power consumption continues to be a critical design metric in high-performance mobile electronics. In order to meet the aggressive power budget targets, chips today need to operate at extremely low power levels, which increases the critical signals’ susceptibility to electromagnetic (EM) crosstalk effects. Because a low-power So... » read more

IP Electromagnetic Crosstalk Requires Contextual Signoff
By Magdy Abadir - 16 Apr, 2018 - Comments: 0

By Magdy Abadir and Anand Raman Continuous advancement in technology scaling is enabling the emergence of high-performance application markets such as artificial intelligence, autonomous cars and 5G communication. These electronic systems operate at multi-GHz speed, while consuming the lowest amount of power possible leaving very little margin for error. Chips in these systems are highly in... » read more

Why Inductance Is Good for Area, Power and Performance
By Magdy Abadir - 12 Mar, 2018 - Comments: 0

By Magdy Abadir and Yehea Ismail For chips designed at advanced technology nodes, interconnect is the dominant contributor towards delay, power consumption, and reliability. Major interconnects such as clock trees, power distribution networks and wide buses play a significant role in chip failure mechanisms such as jitter, noise coupling, power distribution droops, and electro-migration. ... » read more

Pushing Performance Limits
By Brian Bailey - 08 Feb, 2018 - Comments: 0

Trying to squeeze the last bit of performance out of a chip sounds like a good idea, but it increases risk and cost, extends development time, reduced yield, and it may even limit the environments in which the chip can operate. And yet, given the amount of margin added at every step of the development process, it seems obvious that plenty of improvements could be made. "Every design can be o... » read more

New System Requirements Demand a Creatively Choreographed Ecosystem
By Jim Feldhan - 17 Sep, 2015 - Comments: 0

In the past, integrated circuits, packages and boards were all designed independently, and yet in most cases still managed to fit together with very few functional or technical problems. However, recent advances in chip performance have changed this process dramatically. New designs, processes and materials already have been seen in packaging as high-performance semiconductor chips need to c... » read more
