Software-Hardware Co-Design Becomes Real


For the past 20 years, the industry has sought to deploy hardware/software co-design concepts. While it is making progress, software/hardware co-design appears to have a much brighter future. In order to understand the distinction between the two approaches, it is important to define some of the basics. Hardware/software co-design is essentially a bottom-up process, where hardware is deve... » read more

Wearables Disconnect


One of the great opportunities created by the pandemic is a result of conferences going online. I know many people miss the social aspects of not being able to get together with your thousand closest friends, who you see every year at the same shows, but requiring a physical presence is limiting in both time and expense. Personally, I have used the opportunity to "attend" conferences that I wou... » read more

Containing The Explosion In Data


The amount of data that could be kept for every design is gargantuan, but even that may not be enough these days as lifecycle management, continuous verification, regulatory requirements, and globalization add to the data that needs to be stored. But data has no value if it cannot be found or used in ways that provide more benefit than the cost of storing it. "Data management is not unique t... » read more

Wrestling With Analog At 3nm


Analog engineers are facing big challenges at 3nm, forcing them to come up with creative solutions to a widening set of issues at each new process node. Still, these problems must be addressed, because no digital chip will work without at least some analog circuitry. As fabrication technologies shrink, digital logic improves in some combination of power, performance, and area. The process te... » read more

Tradeoffs Between Edge Vs. Cloud


Increasing amounts of processing are being done on the edge, but how the balance will change between what's computed in the cloud versus the edge remains unclear. The answer may depend as much on the value of data and other commercial reasons as on technical limitations. The pendulum has been swinging between doing all processing in the cloud to doing increasing amounts of processing at the ... » read more

Analyzing Electro-Photonic Systems


The design and analysis of electro-optical systems is pushing tools into the complex multi-physics domain, making it challenging to create models that execute at reasonable cost — especially when they include thermal impacts. The lack of models and standards also is slowing the progression of the technology. Still the advantages are worth it to those willing to make the investment. Trad... » read more

Education Vs. Training


While writing my recent articles on the subject of training, a number of people pointed out that training and education are not the same thing. In a very simple sense, training is defined to be learning a skill or behavior that enables you to 'do' something, whereas education is the acquisition of knowledge from study or training. These definitions leave me cold and, in my mind, miss a very ... » read more

Steering The Semiconductor Industry


Progress in semiconductors has been one of the most successful engineering feats, and the industry has ridden an exponential curve longer than anything else in history. It is also a highly conservative industry that has pushed away many disruptive changes in favor of small incremental changes that minimize risk. There have been significant changes over the decades, and they often required a ... » read more

Impact Of GAA Transistors At 3/2nm


The chip industry is poised for another change in transistor structure as gate-all-around (GAA) FETs replace finFETs at 3nm and below, creating a new set of challenges for design teams that will need to be fully understood and addressed. GAA FETs are considered an evolutionary step from finFETs, but the impact on design flows and tools is still expected to be significant. GAA FETs will offer... » read more

Adding Circuit Aging To Variability


Moving to a smaller node usually means another factor becomes important. The industry has become accustomed to doing process, temperature, voltage (PVT) corner analysis, but now it has to add aging into that mix. The problem is that planning for circuit aging is no longer a purely statistical process. Aging is dependent on activity over the lifetime of the device. Tools need to be modified a... » read more
