Trouble Ahead For IC Verification


Verification complexity is roughly the square of design complexity, but until recently verification success rates have remained fairly consistent. That's beginning to change. There are troubling signs that verification is collapsing under the load. The first-time success rate fell (see figure 1) in the last survey conducted by Wilson Research, on behalf of Siemens EDA, in 2022. A new survey ... » read more

Distribution of Currents In Via Arrays


It has become increasingly difficult in recent years to provide adequate PDNs on a PCB. The sheer number of different voltages, combined with increased current demands, makes distributing current around the board a substantial layout challenge. This paper demonstrates that by using appropriate and accurate simulations, combined with the improved intuition that such simulations bring, it is a ch... » read more

Electromigration And IR Drop At Advanced Nodes


Manufacturing chips at 3nm and below is a challenge, but it's only part of the problem. Designing chips that can be manufactured and will actually work is potentially an even bigger problem. There is more data to sift through for place-and-route, less margin to pad a design, and there are more physical effects to contend with as transistors get taller, density increases, and chips age.

Blog Review: May 22


Cadence's Sree Parvathy introduces Verilog-A, a high-level language that uses modules to describe the structure and behavior of analog systems and enables the top-down system to be defined before the actual transistor circuits are assembled. Siemens' Keith Felton suggests the process of package substrate design is improved by leveraging the collective expertise of multiple design domain spec... » read more

High-Level Synthesis Propels Next-Gen AI Accelerators


Everything around you is getting smarter. Artificial intelligence is not just a data center application but will be deployed in all kinds of embedded systems that we interact with daily. We expect to talk to and gesture at them. We expect them to recognize and understand us. And we expect them to operate with just a little bit of common sense. This intelligence is making these systems not just ... » read more

Chip Aging Becoming Key Factor In Data Center Economics


Chip aging is becoming a much bigger concern inside of data centers, where it can impact server uptime, utilization rates, and the amount of energy needed to drive signals and cool entire server racks. Aging in chips is the result of both higher logic utilization and increasing transistor density. This is problematic for data centers, in general, but especially for AI chips where digital log... » read more

Will Domain-Specific ICs Become Ubiquitous?


Questions are surfacing for all types of design, ranging from small microcontrollers to leading-edge chips, over whether domain-specific design will become ubiquitous, or whether it will fall into the historic pattern of customization first, followed by lower-cost, general-purpose components. Custom hardware always has been a double-edged sword. It can provide a competitive edge for chipmake... » read more

Running More Efficient AI/ML Code With Neuromorphic Engines


Neuromorphic engineering is finally getting closer to market reality, propelled by the AI/ML-driven need for low-power, high-performance solutions. Whether current initiatives result in true neuromorphic devices, or whether devices will be inspired by neuromorphic concepts, remains to be seen. But academic and industry researchers continue to experiment in the hopes of achieving significant ... » read more

Power/Performance Costs In Chip Security


Hackers ranging from hobbyists to corporate spies and nation states are continually poking and prodding for weaknesses in data centers, cars, personal computers, and every other electronic device, resulting in a growing effort to build security into chips and electronic systems. The current estimate is that 60% of chips and systems have some type of security built in, and that percentage is ... » read more

High-Level Synthesis Enables The Next Generation Of Edge AI Accelerators


AI is becoming pervasive. But the ever increasing complexity is a challenge for IoT systems. Achieving the highest levels of performance and efficiency in edge AI means going beyond software and off the shelf hardware. Bespoke hardware accelerators in FPGA or ASICs can deliver much higher performance while consuming less energy. Building these accelerators with High-Level Synthesis slashes desi... » read more
