Minimizing The Risk Of Electromagnetic Crosstalk Failures


Leading semiconductor markets, such automotive, machine learning, large scale computing and networking, are driving the need for high density chips that integrate high performance digital cores with sensitive analog/RF IP, while operating at the lowest power and fastest bandwidth possible. These trends are increasing the sensitivity to electromagnetic (EM) coupling, and requiring designers to w... » read more

Taking Inductance And Electromagnetic Effects More Seriously


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?


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, 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 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 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

Preparing For Electromagnetic Crosstalk Challenges


By Magdy Abadir and Anand Raman Electromagnetic (EM) coupling/noise is not a new phenomenon, but increasing bandwidth and decreasing size, along with low-power demands of today’s electronic systems is making EM crosstalk a first order challenge. At clock frequency of 10GHz+ and data rate of 10Gbps+, parasitic inductance and inductive coupling that were previously safe to ignore are no long... » read more

SoC Electromagnetic Crosstalk: From A Tool Perspective


Most commercial electromagnetic (EM) solvers are limited by the size of the design that they can handle, or they may take a very large amount of time or memory to perform the task. These capacity, memory or runtime constraints often lead to dropping important details about the design and the surrounding environment, which in many cases can mask the effects of EM crosstalk, or can lead to the wr... » read more

Electromagnetic (EM) Crosstalk Analysis: Unlocking the Mystery


Ignoring electromagnetic crosstalk is highly risky and can cause significant time-to-market delays as well significant cost over runs. Most current SoC design flows fundamentally ignore inductance and EM effects, and the term “EM crosstalk analysis” may sound Greek to them. This short article provides a quick overview of the basic steps involved in doing EM crosstalk analysis as part of an ... » read more

Crosstalk Analysis At 7nm


The increasing demand for electronic systems with increasing bandwidth and decreasing size puts more high-speed circuitry and high bandwidth channels in ever-closer proximity. The continuous increase in internal clock frequencies (e.g. 5 - 10 GHz) and the increase in data rates (e.g. >10Gbps) are fueling the emergence of electromagnetic (EM) crosstalk issues. Parasitic inductance and indu... » read more
