Last week I attended the Ansys/Apache seminars on “Dimensions of Electronic Design.” The two big challenges as we go down to 28nm and 20nm and below are keeping power manageable and keeping reliability up.
The big challenge with power is that we can put so much stuff on a die and clock it so fast that the power is exceeding… Read More
Intel announced its quarterly results a couple of days ago. They had previously downgraded 3rd quarter sales estimates but they managed to beat the downgraded numbers. If you look at the transcript of the call (I didn’t listen live) you’ll see very little mention of mobile and Atom. This is bad news for Intel. Its core… Read More
The early first generation analog standards all used a technique known as Frequency Division Multiple Access (FDMA). All this means is that each call was assigned its own frequency band in the radio spectrum. Since each band was only allocated to one phone, there was no interference between different calls. When a call finished… Read More
Cadence has apparently announced that going forward the Virtuoso environment is going to be split into two and offered as two separate code-streams, the current IC6.x and a new IC12.x. The idea is to introduce a new product with features that were specifically developed for new technologies such as double patterning aware layout… Read More
At the Linley conference last week I ran into Gordon Brebner of Xilinx. He and I go a long way back. We had adjacent offices in Edinburgh University Computer Science Department back when we were doing our PhDs and conspiring to network the department’s Vax into the university network over a two-week vacation. We managed to … Read More
There’s a nice article on timing closure by Dr. Jason Xing, Vice President of Engineering at ICScape Inc. on the Chip Design website. Not familiar with ICScape? Paul McLellan called ICScape the The Biggest EDA Company You’ve Never Heard Ofand Daniel Payne did Schematic, IC Layout, Clock and Timing Closure from ICScape at… Read More
SpringSoft, soon to be part of Synopsys but officially still a separate company for now, just announced that Laker[SUP]3[/SUP], the third generation of their layout product family, is featured in TSMC’s 20nm Custom Reference Flow.
Laker 20nm advancements include new double patterning-aware design and voltage-dependent… Read More
My new iPad lasts about 10 hours on a single charge and the A5X processor is designed with a 45nm process from Samsung. Processor chips for tablets like this use a multi-voltage IC design flow to reduce total power by:… Read More
Mobile is one of the biggest markets for semiconductor, especially if you count not just mobile handsets but also the base-station infrastructure. No technology has ever been adopted so fast and so completely. There are approximately the same number of mobile phone accounts as there are people in the world. A few people have more… Read More
There is an interesting discussion on the LinkedIn SoC Power Integrity Group in regards to the power integrity challenges for high speed and high frequency designs. More specifically, the additional attention an on-chip power delivery network (PDN) requires as the operating frequency of ICs and SoCs increases.
The PDN has to… Read More
