Photonics technology isn’t new, by any means, but what is new is the drive to leverage high-volume silicon-based semiconductor manufacturing foundries and processes to build chips that can create, sense, modulate, and transmit light. So says Michael White in his latest SiliconEdge column on Electronic Design. The biggest challenge in applying CMOS foundry processes to silicon photonics is creating … Read More
Tools, resources and expertise to help fabless IC designers create successful IC products.
I practice yoga because it helps with my flexibility. Of course, that’s a little like saying that lighting a candle helps with heating your house, but I digress. The point is, flexibility is generally a good thing, and that holds true for 3D ICs and their test strategies. As discussed in the Electrical Engineering Journal, a flexible 3D test strategy that uses a “plug-and-play” architecture… Read More
Trailblazers, followers, and stragglers…semiconductor companies have usually always sorted themselves out along these lines. At 20nm, though ,we’re beginning to see a shift in these classifications that is affecting both technology node adoption and market strategy. Only a few companies are moving to nodes at 20nm and below, while many of the typical followers have decided to stay at 28nm … Read More
While unpredictability may account for the lure of gambling, reliability is an essential part of our everyday lives. Yellowstone National Park, which sits above the Yellowstone Caldera, contains half of the world’s geothermal features. Among the most famous is Old Faithful, a huge geyser that erupts at regular intervals. One reason tourists flock from all over the world to this park is that they know … Read More
Is design-for-test the forgotten stepchild of IC design? Not any more, and DFT engineers can, in large part, thank the automotive industry. The number of processors built into a vehicle is steadily increasing, as we all know (okay, maybe not that guy driving the 1969 Chevy Camaro). These chips have to meet very high standards for quality and reliability, which means the companies who make them need… Read More
Every designer dreads the last-minute engineering change order, or ECO. Just when you think you’re done…you’re not. At 45nm and below, ECOs get even more difficult to implement, because fill now has a direct impact on design performance. A small re-routing can get complicated very quickly with the complex fill requirements of advanced nodes. Fortunately, help is available! On Semiconductor … Read More
The semiconductor industry can (and does) argue about when extreme ultraviolet lithography will be ready for production. However, the actual dates are irrelevant to those engineers who must prepare OPC tools and processes for the EUV-specific effects that will have to be managed in manufacturing. They are busy now, evaluating the impact of such challenges as the distortion caused by EUV shadowing. In … Read More
David Abercrombie recently met with Brian Bailey of Semiconductor Engineering to explain many of the concepts and issues of multi-patterning that he has been writing about for the last couple of years. If you want to understand the basics of multi-patterning requirements, 12 minutes is all you need to check out their first video: Tech Talk: Multipatterning on semiengineering.com. If the video piques … Read More
The terms vector and vectorless modes are commonly used in the context of dynamic power grid (PG) analysis, but what do these terms mean? The PG dynamic simulator uses a design’s activity suite to compute the voltages and currents in the PG network. In vector mode, typically referred as a value change dump (VCD), logic simulation is used to generate the complete activity suite. In vectorless mode, the … Read More
In Standards & Travels on EE Times, Bruce Swanson reminisces about a trip he took to Europe, long before there were cell phones, a common currency, or even the Internet. Dealing with different languages, different currencies, and different local customs took time, was a bit frustrating, and sometimes led to mistakes (WHERE is this train going?!). His experiences on that trip came to mind recently … Read More
At advanced nodes, variability issues lurk behind every design mode, power state, process condition, and manufacturing step. Yet designers must find a way to balance the optimization of multiple operational modes and design corners against the aggressive performance and power targets demanded by today’s fast-moving markets. Concurrent analysis and optimization during place and route operations can provide … Read More
The number of electronic devices used in vehicles is increasing exponentially, for everything from braking to engine control to navigation to collision avoidance. Devices used in safety-critical applications like these not only require very high quality testing at the time of manufacture, but also built-in self-test capability, so they can be tested within the safety-critical application. Advanced design-for-test … Read More
Are you attending the SPIE Advanced Lithography conference beginning Feb 23rd? If so, you’ll want to take note of the following Mentor presentations…there’s something for everyone. For detailed abstracts, go to the SPIE Technical Summaries document. Feb 25, 4:40pm: Feasibility of compensating for EUV field edge effects through OPC Feb 25, 5:20pm: Pattern fidelity verification for logic design in EUV … Read More

Whether you are already working on designs with multi-patterning requirements, or just beginning multi-patterning work, you will benefit from David’s … Read More
Diamonds may not be a designer’s best friend when debugging triple patterning errors. Triple patterning violations can be quite complex, and debugging can be tricky, but the challenges are manageable with software that helps the designer understand the design issues. Learn how to recognize and avoid triple patterning traps in part 2 of The Trouble with Triples on SemiEngineering by multi-patterning … Read More
