Linear Drive Optics May Reduce Data Latency


Optical and electrical are starting to cross paths at a much deeper level, particularly with the growing focus on 3D-ICs and AI/ML training in data centers, driving changes both in how chips are designed and how these very different technologies are integrated together. At the root of this shift are the power and performance demands of AI/ML. It can now take several buildings of a data cente... » read more

Integrating Energy Efficiency Considerations Into Your Design From The Beginning


Data center networking is responsible for consuming about 1% of the global electricity supply. With the advent and integration of AI into various sectors, the pressure on both hardware and software infrastructures, necessitated by neural networks and extensive language models, is expected to increase significantly. The burgeoning energy consumption by hyperscale data centers emerges as an ur... » read more

Unlocking PPA Benefits of Backside Routing


The power delivery network (PDN) is a critical part of any modern semiconductor device. Even with advanced power-saving technologies, today’s chips are hungry for power. Traditionally, power is distributed through metal layers on the same side of the substrate as the signal metal layers. This creates competition for the available layers and pushes the limits of fabrication technology to add m... » read more

Blog Review: April 10


Cadence's Shyam Sharma looks at the evolution of the LPDDR standard and finds that LPDDR5X is opening new specialized markets for low-power DRAMs beyond the traditional areas of mobile, IoT, and automotive. Siemens' Hossam Sarhan and Dusan Petranovic find that new physical verification approaches are needed to ensure the performance and reliability of superconducting ICs and introduce a hybr... » read more

IC Test And Quality Requirements Drive New Collaboration


Rapidly increasing chip and package complexity, coupled with an incessant demand for more reliability, has triggered a frenzy of alliances and working relationships that are starting to redefine how chips are tested and monitored. At the core of this shift is a growing recognition that no company can do everything, and that to work together will require much tighter integration of flows, met... » read more

Reimagining PVT Monitoring IP For Advanced Node GAA Process


As process technology continues to evolve, so must design tools and the IP that support them. One example of an industry evolution is on the PVT monitoring IP side. The process, voltage, and temperature (PVT) monitors embedded within chips provide feedback on silicon status at every stage of the lifecycle, including mission use in the field. The data gathered from the monitors enables benefits ... » read more

Chip Industry Week In Review


By Jesse Allen, Gregory Haley, and Liz Allan. The Japanese government approved $3.9 billion in funding for chipmaker Rapidus to expand its foundry business, of which 10% will be invested in advanced packaging. This is in addition to the previously announced $2.18 billion in funding. In a meeting next week, the U.S. and Japan are expected to cooperate on increasing semiconductor development a... » read more

Integrating ADAS/IVI SoCs Using Automotive IP


The automotive industry continues to evolve the centralized electrical/electronic (EE) architecture, impacting automakers, and Tier 1 and Tier 2 suppliers, as they implement various applications over the next 10 years. The new architecture is structured around a centralized compute module which executes multiple applications such as Advanced Driver Assistance Systems (ADAS)/highly automated dri... » read more

Quantum Computing Challenged By Security, Error Correction


The number and volume of warnings about a post-quantum cryptography (PQC) world are rising, as governments, banks, and other entities prepare for a rash of compromised data and untrustworthy digital signatures. Exactly when this will become a genuine threat is still somewhat fuzzy, because it depends on progress in developing robust qubits. A report by McKinsey & Co. estimates that by 20... » read more

Data Center Security Issues Widen


The total amount of data will swell to about 200 zettabytes of data next year, much of it stored in massive data centers scattered across the globe that are increasingly vulnerable to attacks of all sorts. The stakes for securing data have been rising steadily as the value of that data increases, making it far more attractive to hackers. This is evident in the scope of the attack targets —... » read more
