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

Noise Issues At 10nm And Below

Most of the conversations below 10nm have been about lithography, materials and design constraints. But as companies push to 7nm and beyond, they are faced with a host of new challenges, including how to deal with electromagnetic crosstalk. Electromagnetic crosstalk is unwanted interference caused by the electric and magnetic fields of one or more signals (aggressors) affecting another sign... » read more
