Testing Analog Chips


The world of analog components is broad and diverse, and while testing analog chips may not take as long as running tests on complex SoCs, there are different requirements for analog devices. One type of chip that's seeing more application these days is analog microelectromechanical system devices. Automotive electronics call for a number of [getkc id="37" kc_name="analog"] chips, along with... » 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

Noise At 7nm And Beyond


The digital and analog worlds always have been very different. Digital engineers see the world in terms of electrons and a well-defined set of numerical values. Their waves are discrete and squared off and their devices are often noisy when they turn on and off. Analog engineers think in terms of quiet, smooth waves, and they are very concerned about anything that can disrupt those waves, such ... » read more

Tech Talk: EM Crosstalk


Anand Raman, senior director at Helic, talks about the impact of electromagnetic interference on digital design at 10/7nm and beyond. Once confined to the analog space, noise is suddenly an issue at advanced nodes for all designs. At the root of the problem are smaller nodes, increased speed and higher levels of integration. https://youtu.be/hzZqK2lNJNQ » read more

Semiconductor Wafer Demand: Growing Pains


Semico Research is forecasting total semiconductor unit growth to exceed 13% this year, the first double-digit growth year since 2010. The exceptional unit growth is what the industry hopes for, but it does come with some growing pains. MOS logic, optoelectronics, MEMS and sensors, and even analog and discrete products are experiencing more than 10% unit growth in 2017. The challenge is that... » read more

New Drivers For I/O


Interface standards are on a tear, and new markets are pushing the standards in several directions at the same time. The result could be a lot more innovation and some updates in areas that looked to be well established. Traditionally, this has been a sleepy and predictable part of the industry with standards bodies producing updates to their interfaces at a reasonable rate. Getting data int... » read more

Mixed Messages For Mixed-Signal


There is no such thing as a purely digital design at advanced nodes today. Even designs that have no [getkc id="37" kc_name="analog"] content are likely relying on [getkc id="38" kc_name="mixed-signal"] components such as SerDes for communications, or voltage regulators for adaptive power control. But the days of purposely attempting to integrate everything including analog and RF onto a single... » read more

What’s Missing In Packaging


The growth of advanced packaging on the leading edge of design is inching backwards into older nodes. With most technology—tools, methodologies, materials and processes—this is business as usual. But in packaging, it's both counterintuitive and potentially problematic. The main reason that companies began investing in advanced packaging—OSATs, foundries, chipmakers such as Intel and Qu... » read more

Noise Abatement


[getkc id="285" kc_name="Noise"] is a fact of life. Almost everything we do creates noise as a by-product and quite often what is a signal to one party is noise to another. Noise cannot be eliminated. It must be managed. But is noise becoming a larger issue in chips as the technology nodes get smaller and packaging becomes more complex? For some, the answer is a very strong yes, while for ot... » read more
