Improving Verification Methodologies


Methodology improvements and automation are becoming pivotal for keeping pace with the growing complexity and breadth of the tasks assigned to verification teams, helping to compensate for lagging speed improvements in the tools. The problem with the tools is that many of them still run on single processor cores. Functional simulation, for example, cannot make use of an unlimited number of c... » read more

Lines Blurring Between Supercomputing And HPC


Supercomputers and high-performance computers are becoming increasingly difficult to differentiate due to the proliferation of AI, which is driving huge performance increases in commercial and scientific applications and raising similar challenges for both. While the goals of supercomputing and high-performance computing (HPC) have always been similar — blazing fast processing — the mark... » read more

Multi-Die Design Complicates Data Management


The continued unbundling of SoCs into multi-die packages is increasing the complexity of those designs and the amount of design data that needs to be managed, stored, sorted, and analyzed. Simulations and test runs are generating increasing amounts of information. That raises questions about which data needs to be saved and for how long. During the design process, engineers now must wrestle ... » read more

What Scares Chip Engineers About Generative AI


Experts At The Table: LLMs and other generative AI programs are a long way away from being able to design entire chips on their own from scratch, but the emergence of the tech has still raised some genuine concerns. Semiconductor Engineering sat down with a panel of experts, which included Rod Metcalfe, product management group director at Cadence; Syrus Ziai, vice-president of engineering at E... » read more

Linear Pluggable Optics Save Energy In Data Centers


Linear pluggable optics (LPO) is garnering more attention as a way to quickly and efficiently move data in and out of server racks, but a lack of standards for connecting the optical modules is slowing adoption at a time when there is growing pressure to reduce power in data centers. LPO is the newest of two approaches to solving the power wall problem in data centers. Co-packaged optics (CP... » read more

Interconnects Approach Tipping Point


As leading devices move to next generation nanosheets for logic, their interconnections are getting squeezed past the point where they can deliver low resistance pathways. The 1nm (10Å) node will have 20nm pitch and larger metal lines, but the interconnect stack already consumes a third of device power and accounts for 75% of the chip's RC delay. Changing this dynamic requires a superior co... » read more

Memory Wall Problem Grows With LLMs


The growing imbalance between the amount of data that needs to be processed to train large language models (LLMs) and the inability to move that data back and forth fast enough between memories and processors has set off a massive global search for a better and more energy- and cost-efficient solution. Much of this is evident in the numbers. The GPU market is forecast to reach $190 billion in ... » read more

What’s Next In Advanced Packaging?


Experts at the Table: Semiconductor Engineering sat down to discuss 3D-IC progress and issues, photonics, and tradeoffs with different interposers and bridge technologies, with Michael Kelly, vice president of Chiplets and FCBGA Integration at Amkor; William Chen, fellow at ASE; Dick Otte, CEO of Promex Industries; and Sander Roosendaal, R&D director at Synopsys Photonics Solutions. What fo... » read more

ADAS Adds Complexity To Automotive Sensor Fusion


Sensor fusion is becoming increasingly popular and more complex in automotive designs, integrating multiple types of sensors into a single chip or package and intelligently routing data to wherever it is needed. The primary goal is to bring together information from cameras, radar, lidar, and other sensors in order to provide a detailed view of what's happening inside and outside of a vehicl... » read more

Signal Integrity Plays Increasingly Critical Role In Chiplet Design


Maintaining the quality and reliability of electrical signals as they travel through interconnects is proving to be much more challenging with chiplets and advanced packaging than in monolithic SoCs and PCBs. Signal integrity is a fundamental requirement for all chips and systems, but it becomes more difficult with chiplets due to reflections, loss, crosstalk, process variation, and various ... » read more
