Blog Review: Mar. 26


Siemens' Bianca Ward argues that sustainability must be considered starting from the design phase to reduce the energy consumption of ICs as well as the production processes used to manufacture them. Synopsys' Adrien Tozzoli looks at how physical optics simulation can be improved by using beam synthesis propagation, a method that decomposes the optical field into a collection of beamlets to ... » read more

Allegro X AI for Generative System Design


PCB design is the act of realizing a schematic into a physical form. Currently, human designers use electronic design automation (EDA) software to combine component placement and routing to realize the electrical connectivity on a manufacturable PCB. Computer-aided design (CAD) tools have been used in the design flow since the 1970s and are now an essential part of the designer’s toolkit. Som... » read more

Chip Industry Week In Review


Semiconductor industry energy consumption grew 125% between 2015 and 2023, while direct greenhouse gas emissions rose 23% in the same period, according to the Europe think tank Interface, which analyzed corporate social responsibility reports from 28 global chip manufacturers. CSIS' new report "Understanding U.S. Allies’ Current Legal Authority to Implement AI and Semiconductor Export Cont... » read more

What Exactly Are Chiplets And Heterogeneous Integration?


The terms “chiplet” and “heterogeneous integration” fill news pages, conference papers, and marketing presentations, and for the most part engineers understand what they're reading. But speakers sometimes stumble during a presentation trying to figure out whether a particular die qualifies as a chiplet, and heterogeneous integration comes in different guises for different people. Both t... » read more

Blog Review: Mar. 19


Cadence's Neelabh Singh explains the defined port operations of USB4 that are used to bring transmitters burst and receivers of a design under test into compliance mode and to execute tests like bit error tests, error rate tests, clock switch tests, TxFFE equalization tests, and electrical idle tests. Siemens EDA's Stephen V. Chavez examines the use of blind and buried vias in high-density i... » read more

New Data Center Protocols Tackle AI


Compute nodes in AI and HPC data centers increasingly need to reach out beyond the chip or package for additional resources to process growing workloads. They may commandeer other nodes in a rack (scale-up) or employ resources in other racks (scale-out). The problem is there currently is no open scale-up protocol. So far this task has been dominated by proprietary protocols, because much of ... » read more

Chip Industry Week In Review


ASML and imec signed a five-year strategic partnership to advance semiconductor innovation and sustainable technology. The collaboration will leverage ASML’s full product portfolio, including high-NA EUV, DUV immersion, and advanced metrology tools, within imec’s pilot line for sub-2nm R&D. Supported by EU and national funding, it will also drive research in silicon photonics, memory, a... » read more

Static Timing Analysis: Cell Delay Vs. Cell Drive Strength


Have you ever wondered how a predator succeeds or its prey escapes in the jungle? It’s the breathtaking speed and agility of the predator (say, a leopard) as it chases prey (say, a deer). The VLSI circuit operation is very similar. If the driving cell is strong, it takes less delay and changes the output quicker than a weaker driver, which produces a sluggish response and takes longer t... » read more

3D-IC For The Masses


The concepts of 3D-IC and chiplets have the whole industry excited. It potentially marks the next stage in the evolution of the IP industry, but so far, technical difficulties and cost have curtailed its usage to just a handful of companies. Even within those, they do not appear to be seeing benefits from heterogeneous integration or reuse. Attempts to make this happen are not new. "A decade... » read more

Chiplets Add New Power Issues


Delivering and managing power are becoming key challenges in the rollout of chiplets, adding significantly to design complexity and forcing chipmakers to weigh tradeoffs that can have a big impact on the performance, reliability, and the overall cost of semiconductors. Power is a concern for every chip and chiplet design, even if the specifics differ based on the application. Systems vendors... » read more
