What Exactly Are Chiplets And Heterogeneous Integration?
By Bryon Moyer - 20 Mar, 2025 - Comments: 0

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
By Jesse Allen - 19 Mar, 2025 - Comments: 0

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
By Bryon Moyer - 17 Mar, 2025 - Comments: 0

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
By The SE Staff - 14 Mar, 2025 - Comments: 0

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
By Pamula Sai Srinivas - 13 Mar, 2025 - Comments: 0

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
By Brian Bailey - 13 Mar, 2025 - Comments: 0

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
By Ann Mutschler - 13 Mar, 2025 - Comments: 0

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

Why Choose External CFD Modeling? Recommended by The Green Grid, it helps predict: ... » read more

Blog Review: Mar. 12
By Jesse Allen - 12 Mar, 2025 - Comments: 0

Cadence's P. Saisrinivas explains the relationship between drive strength and cell delay and why it is key to choose the appropriate drive strength to meet timing constraints while minimizing power and area. Siemens' Daniel Berger and Dirk Hartmann tackle the readout problem of accurately measuring the state of a quantum system after it has undergone a quantum computation, which becomes incr... » read more

Pioneering The Cosmos With Physical AI: Robots Are Humanity’s Key Partners
By Steve Brown - 06 Mar, 2025 - Comments: 0

The stars have always fascinated us, sparking dreams of exploration and discovery. But now, as humanity steps further into the cosmos, a new hero takes center stage—physical AI. Robots, autonomous vehicles, and drones are transforming our ability to explore and settle other worlds, from navigating the alien terrain of Mars to constructing future bases on the Moon. These cutting-edge... » read more
