  • 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 […]

  • IP Electromagnetic Crosstalk Requires Contextual Signoff

    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 integrated with multiple noise sensitive analog […]

  • Preparing For Electromagnetic Crosstalk Challenges

    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 longer. System-on-chip […]

  • Mixed-Signal Issues Worse At 10/7nm

    Despite increasingly difficulty in scaling digital logic to 10/7nm, not all designs at the leading edge are digital. In fact, there are mixed-signal components in designs at almost all nodes down to 10/7nm. This may seem surprising because analog scaling has been an issue since about 90nm, but these are not traditional analog components. Analog […]

  • SoC Electromagnetic Crosstalk: From A Tool Perspective

    Why most of the commercial electromagnetic solvers and extraction engines are not suitable for analyzing EM crosstalk in a typical SoC design.   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 […]

  • 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 At 7nm

    Faster speed and smaller features are increasing the noise volume. 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 […]

  • Electromagnetic (EM) Crosstalk: Challenges and Trends

    Abstract— With the advent of advanced technologies and System on-Chip (SoC) architectures, ignoring electromagnetic crosstalk is highly risky resulting in significant delays in reaching the market on time as well significant cost over runs. This short article provides a quick definition of electromagnetic crosstalk, in the context of modern SoC designs, and the technology and […]

  • 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 […]
