Blog Review: Nov. 6


Cadence's Satish Kumar C explores how the Deferrable Memory Write transaction type in PCIe and CXL can improve latency, efficiency, and performance by delaying certain memory write operations during system bus congestion or until other priority tasks are complete and highlights implementation and verification challenges. Synopsys' Daryl Seitzer and Rahul Thukral point to magnetoresistive RAM... » read more

Managing Reflections With Terminations


Have you heard recommendations to use a particular termination in particular situations for good signal integrity? Have you ever wondered how to incorporate terminations in your design? While there are typical use cases for various terminations, sometimes engineers use termination techniques based on a recommendation or assumption that may not work, or at least may not be optimal, for their par... » read more

Chip Industry Week In Review


Siemens announced plans to acquire Altair Engineering, a provider of industrial simulation and analysis, data science, and high-performance computing (HPC) software, for about $10 billion. Altair's software will become part of Siemens' Xcelerator portfolio and provide a boost to physics-based digital twins. Onto Innovation bought Lumina Instruments, a San Jose, California-based maker of lase... » read more

Chiplets Make Progress Using Interconnects As Glue


Breaking up SoCs into their component parts and putting those and other pieces together in some type of heterogeneous assembly is beginning to take shape, fueled by advances in interconnects, complex partitioning, and industry learnings about what works and what doesn't. While the vision of plug-and-play remains intact, getting there is a lot more complicated than initially imagined. It can ... » read more

HW and SW Architecture Approaches For Running AI Models


How best to run AI inference models is a current topic of much debate as a wide breadth of systems companies look to add AI to a variety of systems, spurring both hardware innovation and the need to revamp models. Hardware developers are making progress with AI accelerators and SoCs. But on the model side, questions abound about whether the answer might come from revisiting older, less compl... » read more

RISC-V Conformance


Experts At The Table: Despite growing excitement and participation in the development of the RISC-V ecosystem, significant holes remain in the development flow. One of the most concerning is conformance, which must exist before software portability becomes possible. Semiconductor Engineering discussed the issue with John Min, vice president of customer service at Arteris; Zdeněk Přikryl, CTO... » read more

Blog Review: Oct. 30


Synopsys' Frank Schirrmeister argues that hardware-assisted verification techniques like emulation and prototyping are essential to help engineers improve design behavior to manage complexity and ensure systems function seamlessly in real-world applications. Siemens’ Stephen V. Chavez finds that ultra high-density interconnect (UHDI) has changed the design and production of PCBs to enable ... » read more

Chip Industry Week In Review


Europe's top court ruled in Intel's favor, voiding a $1.1 billion fine imposed by the European Union and dismissing charges of anti-competitive behavior. IBM released yield benchmarks for high-NA EUV, which serve as proof points that the newest advanced litho equipment will enable scaling beyond the 2nm process node. Also on the lithography front, Nikon is developing a maskless digital litho... » read more

New Approaches To Power Decoupling


Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and various types of advanced packaging, new approaches are needed. Power is a much more important factor than it used to be, especially in the era of AI. “Doing an AI search consumes 10X the power t... » read more

Blog Review: Oct. 23


Cadence’s Sanjeet Kumar introduces the message bus interface in the PHY Interface for the PCIe, SATA, USB, DisplayPort, and USB4 Architectures (PIPE) specification, which provides a way to initiate and participate in non-latency-sensitive PIPE operations using a small number of wires. Siemens’ Dennis Brophy argues that the recently published Portable Test and Stimulus Standard (PSS) 3.0 ... » read more
