Recently, I discussed the increasing risk of metastability hazards at nanoscale geometries. These risks are significantly aggravated at low supply voltages and low temperatures and must be addressed during the design cycle of any mission critical application. This time I discuss what it takes to estimate a synchronizer’s … Read More
Increasingly, SoC designs consist of assembling blocks of pre-designed IP. One special case is the derivative design where not just the IP blocks get re-used but a lot of the assembly itself. For example, in the design below some blocks are added, some blocks are updated, some hierarchy is changed. But the bulk of the design remains… Read More
The growing amount of electronics within today’s automobiles is driving very high quality and reliability requirements to a widening range of semiconductor devices. At the same time, traditional fault models are becoming less effective at achieving desired silicon quality levels. Improvements in test solutions are needed… Read More
One of the most challenging stages in an SoC design is achieving timing closure. Actually design closure is perhaps a better term since everything needs to come together such as clock tree, power nets, power budget and so on. Changes made to the design are known as ECOs (which stands for engineering change orders, a term that comes… Read More
Interface IP typically consists of multiple layers, most importantly a PHY (level 1) analog (or mixed signal) block that handles the interface to the outside world and a number of levels of digital controllers. The interfaces between all these levels, especially between the PHY and the controller, is often defined by the interface… Read More
Virtual platforms enable software development to take place on a model of an electronic system. What everyone would like is models that are fast and accurate but that is simply not possible. Fast models are fast because they don’t model everything at the signal level. And accurate models get to be accurate by handling a lot of detail… Read More

As we have moved towards extremely low process nodes with very high chip density, the cost of mask preparation also has become exorbitantly high. It has become essential to know about the failure rates and mitigate the same at the design time before chip fabrication, and also to make sure about chip reliability over time as it is constantly… Read More
On the Tuesday of DAC I moderated a panel session on Hardware Assisted Verification in 10 Years: More Need, More Speed. Although this topic obviously could include FPGA-based prototyping, in fact we spent pretty much the whole time talking about emulation. Gary Smith, on Sunday night, actually set up things by pointing out that… Read More
This was my 30[SUP]th[/SUP] DAC and the second most memorable. The most memorable was my second DAC (1985) in Las Vegas with my new bride. We had a romantic evening ending with ice cream sundaes at midnight that we still talk about. This year SemiWiki had Dr. Paul McLellan, Dr. Eric Esteve, Daniel Payne, Don Dingee, Randy Smith, and… Read More
