The Evolution of HBM


High-bandwidth memory originally was conceived as a way to increase capacity in memory attached to a 2.5D package. It has since become a staple for all high-performance computing, in some cases replacing SRAM for L3 cache. Archana Cheruliyil, senior product marketing manager at Alphawave Semi, talks about how and where HBM is used today, how it will be used in the future, why it is essential fo... » read more

Top-Down Vs. Bottom-Up Chiplet Design


Chiplets are gaining widespread attention across the semiconductor industry, but for this approach to really take off commercially it will require more standards, better modeling technologies and methodologies, and a hefty amount of investment and experimentation. The case for chiplets is well understood. They can speed up time to market with consistent results, at whatever process node work... » 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

Poised to merge communication and computing, 6G promises to create a hyperconnected world that blends digital and physical experiences with ultra-fast speeds and low latency as a start... » 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

Partitioning In The Chiplet Era


The widespread adoption of chiplets in domain-specific applications is creating a partitioning challenge that is much more complex than anything chip design teams have dealt with in previous designs. Nearly all the major systems companies, packaging houses, IDMs, and foundries have focused on chiplets as the best path forward to improve performance and reduce power. Signal paths can be short... » read more
