Symptoms Of SoC Electromagnetic (EM) Crosstalk


By Anand Raman and Magdy Abadir Have you ever had your silicon demonstrate unexpected behavior? Have you ever found unexplainable design failure or performance degradation? A number of issues could be the culprit - from overloaded signal nets, a noisy power grid, or increasing temperature - but one problem often overlooked is electromagnetic (EM) crosstalk. Electromagnetic (EM) crosstal... » read more

Chip Aging Accelerates


Reliability is becoming an increasingly important proof point for new chips as they are rolled out in new markets such as automotive, cloud computing and industrial IoT, but actually proving that a chip will function as expected over time is becoming much more difficult. In the past, reliability generally was considered a foundry issue. Chips developed for computers and phones were designed ... » read more

New Thermal Issues Emerge


Thermal monitoring is becoming more critical as gate density continues to increase at each new node and as chips are developed for safety critical markets such as automotive. This may sound counterintuitive because the whole point of device scaling is to increase gate density. But at 10/7 and 7/5nm, static current leakage is becoming a bigger issue, raising questions about how long [getkc id... » read more

Pushing Performance Limits


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

Predictions: Manufacturing, Devices And Companies


Some predictions are just wishful thinking, but most of these are a lot more thoughtful. They project what needs to happen for various markets or products to become successful. Those far reaching predictions may not fully happen within 2018, but we give everyone the chance to note the progress made towards their predictions at the end of the year.

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‚Äôs 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

Turning Down The Power


Chip and system designers are giving greater weight to power issues these days. But will they inevitably hit a wall in accounting for ultra-low-power considerations? Performance, power, and area are the traditional attributes in chip design. Area was originally the main priority, with feature sizes constantly shrinking according to Moore's Law. Performance was in the saddle for many years. M... » read more

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 IP increasingly includes highly integrated, mix... » read more

The Trouble With Models


Models are becoming more difficult to develop, integrate and utilize effectively at 10/7nm and beyond as design complexity, process variation and physical effects add to the number of variables that need to be taken into account. Modeling is a way of abstracting the complexity in various parts of the semiconductor design, and there can be dozens of models required for complex SoCs. Some are ... » read more

The Week In Review: Design


M&A Synopsys finalized its acquisition of Black Duck Software, which provides software for managing and securing open source software in projects, adding to Synopsys' burgeoning software analysis and security business. The cash deal was approximately $547 million net of cash acquired. STMicroelectronics acquired Atollic, maker of the Eclipse-based TrueSTUDIO Integrated Development Envir... » read more
