CPU Performance Bottlenecks Limit Parallel Processing Speedups


Multi-core processors theoretically can run many threads of code in parallel, but some categories of operation currently bog down attempts to raise overall performance by parallelizing computing. Is it time to have accelerators for running highly parallel code? Standard processors have many CPUs, so it follows that cache coherency and synchronization can involve thousands of cycles of low-le... » read more

Analog Consolidation Spurs New Round Of Startups


A new wave of startups is rising to meet the growing need for specialized analog customization in chip design projects, opening the door to more affordable custom designs. These startups are breathing new life into a sector, which as a result of consolidation has favored only the largest chipmakers. As larger analog companies acquire smaller ones, many companies that were previously engaged ... » read more

Power Delivery Challenged By Data Center Architectures


Processor and data center architectures are changing in response to the higher voltage needs of servers running AI and large language models (LLMs). At one time, servers drew a few hundred watts for operation. But over the past few decades that has changed drastically due to a massive increase in the amount of data that needs to be processed and user demands to do it more quickly. NVIDIA's G... » read more

Voltage Drop Now Requires Dynamic Analysis


At one time a relatively infrequent occurrence, voltage drop is now a major impediment to reliability at advanced nodes. Decades ago, voltage drop was only an issue for very large and high-speed designs, where there was concern about supply lines delivering full voltage to transistors. As design margins have tightened in modern advanced designs, controlling voltage drop has become a requiremen... » read more

Focus Shifts To Application-Specific Workloads


Experts At The Table: EDA has undergone numerous workflow changes over time. Different skill sets have come into play over the years, and at times this changed the definition of what it means to design at the system level. To work out what this means for designers today, and how it looks going forward, Semiconductor Engineering sat down with Michal Siwinski, chief marketing officer at Arteris; ... » read more

AI/ML’s Role In Design And Test Expands


The role of AI and ML in test keeps growing, providing significant time and money savings that often exceed initial expectations. But it doesn't work in all cases, sometimes even disrupting well-tested process flows with questionable return on investment. One of the big attractions of AI is its ability to apply analytics to large data sets that are otherwise limited by human capabilities. In... » read more

Metrology And Inspection For The Chiplet Era


New developments and innovations in metrology and inspection will enable chipmakers to identify and address defects faster and with greater accuracy than ever before, all of which will be required at future process nodes and in densely packed assemblies of chiplets. These advances will affect both front-end and back-end processes, providing increased precision and efficiency, combined with a... » read more

Driving Cost Lower and Power Higher With GaN


Gallium nitride is starting to make broader inroads in the lower-end of the high-voltage, wide-bandgap power FET market, where silicon carbide has been the technology of choice. This shift is driven by lower costs and processes that are more compatible with bulk silicon. Efficiency, power density (size), and cost are the three major concerns in power electronics, and GaN can meet all three c... » read more

Chip Security Now Depends On Widening Supply Chain


Securing chips is becoming more challenging as SoCs are disaggregated into chiplets, creating new vulnerabilities that involve hardware and software, as well as multiple entities, and extending threats across a much broader supply chain. In the past, much of the cyber threat model was confined to either hardware or software, and where multiple vendors were involved, various chips were separa... » read more

Post-Quantum Computing Threatens Fundamental Transport Protocols


The Transport Level Security (TLS) protocol is one of the few rock-steady spots in the rapidly changing computing industry, but that's about to change as quantum computers threaten traditional encryption schemes. Because TLS is fundamental to network communications, including allowing Internet of Things (IoT) devices to function properly, researchers already are exploring both hardware and s... » read more
