UMI: Extending Chiplet Interconnect Standards To Deal With The Memory Wall


With the Open Compute Project (OCP) Summit upon us, it’s an appropriate time to talk about chiplet interconnect (in fact the 2024 OCP Summit has a whole day dedicated to the multi-die topic, on October 17). Of particular interest is the Bunch of Wires (BoW) interconnect specification that continues to evolve. At OCP there will be an update and working group looking at version 2.1 of BoW.

What Comes After HBM For Chiplets


Experts At The Table: Semiconductor Engineering sat down to discuss what will trigger the creation of a commercial chiplet marketplace, and what those chiplet-based designs will look like, with Elad Alon, CEO of Blue Cheetah; Mark Kuemerle, vice president of technology at Marvell; Kevin Yee, senior director of IP and ecosystem marketing at Samsung; Sailesh Kumar, CEO of Baya Systems; and Tanuja... » read more

Defining The Chiplet Socket


Experts At The Table: The semiconductor industry has been buzzing with the possibilities surrounding chiplets, but so far this packaging technology has been confined to large semiconductor companies that are vertically integrated. The industry has been attempting to open this up to a broader group of people. To work out what this means for chiplets, and what standardization will be required, Se... » read more

Intel Vs. Samsung Vs. TSMC


The three leading-edge foundries — Intel, Samsung, and TSMC — have started filling in some key pieces in their roadmaps, adding aggressive delivery dates for future generations of chip technology and setting the stage for significant improvements in performance with faster delivery time for custom designs. Unlike in the past, when a single industry roadmap dictated how to get to the next... » read more

Accellera Preps New Standard For Clock-Domain Crossing


Part of the hierarchical development flow is about to get a lot simpler, thanks to a new standard being created by Accellera. What is less clear is how long will it take before users see any benefit. At the register transfer level (RTL), when a data signal passes between two flip flops, it initially is assumed that clocks are perfect. After clock-tree synthesis and place-and-route are perfor... » read more

Integration Challenges For RISC-V Designs


One of the big draws of RISC-V is that it allows design teams to create unique chips or chiplets and to make modifications to the instruction-set architecture. That extra degree of freedom also creates some issues when it comes to integrating those designs into packages or systems because they may require non-standard connectivity approaches. Frank Schirrmeister, vice president of marketing at ... » read more

UCIe Goes Back To The Drawing Board


The integration of multiple dies within a single package increasingly is viewed as the next evolution for extending Moore’s Law, but it also presents myriad challenges — particularly in achieving a universally accepted standard integrating plug-and-play chiplets from different vendors. “In some respects, people are already doing this,” says Debendra Das Sharma, Intel senior fellow an... » read more

Why Chiplets Are So Critical In Automotive


Chiplets are gaining renewed attention in the automotive market, where increasing electrification and intense competition are forcing companies to accelerate their design and production schedules. Electrification has lit a fire under some of the biggest and best-known carmakers, which are struggling to remain competitive in the face of very short market windows and constantly changing requir... » read more

IC Package Physical Design Best Practices


Historically IC package design has been a relatively simple task which allowed the die bumps to be fanned out on a package substrate to a floorplan geometry suitable for connecting to a printed circuit board (PCB). But today the industry is moving to disaggregation of traditional monolithic SoC functions into chiplets often interfaced with local high-speed memory to avoid silicon reticle limits... » read more

2023: A Good Year For Semiconductors


Looking back, 2023 has had more than its fair share of surprises, but who were the winners and losers? The good news is that by the end of the year, almost everyone was happy. That is not how we exited 2022, where there was overcapacity, inventories had built up in many parts of the industry, and few sectors — apart from data centers — were seeing much growth. The supposed new leaders we... » read more
