Blog Review: April 17


Siemens' Sumit Vishwakarma highlights the importance of crystal oscillators to the proper functioning of many semiconductor devices and applications, from clock signals to transmission and reception of radio waves. Cadence's Jay Domadia introduces some of the new features in GDDR7, such as a semi-independent row and column command address bus and two modes of data signaling, enabling PAM3 fo... » read more

Using AI/ML To Minimize IR Drop


IR drop is becoming a much bigger problem as technology nodes scale and more components are packed into advanced packages. This is partly a result of physics, but it's also the result of how the design flow is structured. In most cases, AI/ML can help. The underlying problem is that moving to advanced process nodes, and now 3D-ICs, is driving current densities higher, while the power envelop... » read more

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

PCI Express Test Overview


PCl Express, short for Peripheral Component Interconnect Express, is a high-performance and high-bandwidth serial communication interconnect standard. First proposed by Intel and further developed by the Peripheral Component Interconnect Special Interest Group (PCI-SIG) in replacement of bus-based communication architecture, such as PCI, PCI Extended (PCI-X), and Accelerated Graphics Port (AGP)... » 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

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

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

Blog Review: Apr. 3


Siemens' Keith Felton finds that high bandwidth memory integration poses significant challenges for package designers stemming from its unique architecture and stringent performance requirements. Synopsys' Gervais Fong finds out what's new in the USB4 v2 specification, some of its unique challenges involved in doubling the performance capabilities of the USB wired connection, and an intrigui... » read more

Chip Industry Week In Review


By Adam Kovac, Karen Heyman, and Liz Allan.  China introduced strict procurement guidelines aimed at blocking the use of AMD and Intel processors in government computers. Meanwhile, China urged the Netherlands to ease restrictions on deep ultraviolet (DUV) litho equipment, according to Nikkei Asia. DUV is an older technology, based on 193nm ArF lasers, but in conjunction with multi-p... » read more

Interconnects Essential To Heterogeneous Integration


Designing and manufacturing interconnects is becoming more complex, and more critical to device reliability, as the chip industry shifts from monolithic planar dies to collections of chips and chiplets in a package. What was once as simple as laying down a copper trace has evolved into tens of thousands of microbumps, hybrid bonds, through-silicon vias (TSVs), and even junctions for optical ... » read more
