The Bumpy Road To FinFETs


The shift from planar transistors to finFETs is a major inflection point in the IC industry. FinFETs are expected to enable higher performance chips at lower voltages. And the next-generation transistor technology also could allow the industry to extend CMOS to the 10nm node and perhaps beyond. But as it turns out, finFET technology is also harder to master than previously thought. For exam... » read more

What’s Wrong With Power Signoff


Power signoff used to be a checklist item before a design went to tapeout. But as power has become a critical factor in designs, particularly at advanced nodes, signing off on power now needs to be done at multiple points throughout the design flow. That alone adds even greater complexity to already complex design processes because it requires fixed reference points and scenarios for taking mea... » read more

FinFET Learning


FinFETs are not simple to work with. They’re difficult to manufacture, tricky to design, and they run the risk of greatly increased dynamic power density—particularly at 14/16nm, where extra margin is hard to justify—which affects everything from electromigration to signal integrity. Moreover, while finFETs have been on the drawing board for more than a decade, it’s taken four years ... » read more

Pointing Fingers, Often In The Wrong Direction


Every design these days, regardless of whether it’s a processor, an SoC, an ASIC, FPGA or stacked die, relies on a combination of re-used and third-party intellectual property. No company—not even Intel, Apple or Samsung—has the capability of building everything itself within a highly compressed market window. There is a spectrum of IP use and re-use, of course. In some cases, it may i... » read more

FinFET-Based Designs: Power Sign-off Considerations


FinFET devices can operate at ultra-low sub-1V nominal supply voltage levels without impacting their delays. This allows for low power, higher performance designs needed for many of todays’ applications. These devices also have considerably higher drive strengths, allowing faster operating speeds. However, this can result in more localized di/dt current scenarios, and when coupled with more r... » read more

The Week In Review: Design


Tools CEVA integrated Bluetooth processing into its DSP cores. In addition to audio and video and always-on capabilities, the company is pitching the combination as an all-in-one, ultra-low-power solution for the wearable electronics market. So how big is this market opportunity? IDC predicts the wearable computing market will grow from 19.2 million units this year to 112 million units in 2... » read more

Blog Review: April 30


Applied Materials’ Jeremy Read points to a looming problem for the Internet of Things—legacy fabs that will require software upgrades and advanced process control. Also needed: Sensors attached to thousands of machines for predictive maintenance. Foundries are now ready for production finFETs. Cadence's Richard Goering captures the buzz at last week’s TSMC Tech Symposium, where the ro... » read more

Follow The Investments


Where is design heading over the next few years. The best way to tell that is to find out where the development dollars are going, and foundries and tools always precede actual designs. The foundries are starting to spend money—lots of it—on finFETs and 28nm. And while they’re talking about 2.5D and 3D, the money isn’t going there just yet. In fact, there are two different processes ... » read more

The Week In Review: Design


Certifications TSMC certified Mentor Graphics’ DFM, place and route and custom IC tools, as well as its SPICE simulator, for the 16nm finFET process.  The foundry also certified Cadence’s digital and custom/analog tools for that process, including physical verification, QRC extraction, timing sign off and its power integrity solution. And it certified Synopsys’ digital and custom soluti... » read more

Gaps In Metrology Could Impact Yield


For some time, chipmakers have been developing new and complex chip architectures, such as 3D NAND, finFETs and stacked die. But manufacturing these types of chips is no simple task. It requires a robust fab flow to enable new IC designs with good yields. In fact, yield is becoming a more critical part of the flow. Yield is a broad term that means different things to different parts of the ... » read more
