Chip Aging Opens Up New Attack Vectors


The longer a piece of silicon is out in the field the more prone it becomes to a cyberattack, raising questions about the optimal longevity of circuits and the impact of extending their lifetimes. This is particularly challenging for safety- and mission-critical applications, where the cost of development can run as high as $100 million for some of the most complex designs. Chipmakers want t... » read more

Benefits And Challenges In Multi-Die Assemblies


Experts at the Table: Semiconductor Engineering sat down to discuss chiplets, hybrid bonding, and new materials with Michael Kelly, vice president of Chiplets and FCBGA Integration at Amkor; William Chen, fellow at ASE; Dick Otte, CEO of Promex Industries; and Sander Roosendaal, R&D director at Synopsys Photonics Solutions. What follows are excerpts of that discussion. To view part one of t... » read more

Unleashing AI Potential Through Advanced Chiplet Architectures


The rapid proliferation of machine-generated data is driving unprecedented demand for scalable AI infrastructure, placing extreme pressure on compute and connectivity within data centers. As the power requirements and carbon footprint of AI workloads rise, there is a critical need for efficient, high-performance hardware solutions to meet growing demands. Traditional monolithic ICs will not sca... » read more

Challenges In Managing Chiplet Resources


Managing chiplet resources is emerging as a significant and multi-faceted challenge as chiplets expand beyond the proprietary designs of large chipmakers and interact with other elements in a package or system. Poor resource management in chiplets adds an entirely new dimension to the usual power, performance, and area tradeoffs. It can lead to performance bottlenecks, because as chiplets co... » read more

Evaluation Tool For The Cost Impacts Of Chiplet-Specific Design Choices


A new technical paper titled "CATCH: a Cost Analysis Tool for Co-optimization of chiplet-based Heterogeneous systems" was published by researchers at UCLA, Duke University and Arizona State University. Abstract "With the increasing prevalence of chiplet systems in high-performance computing applications, the number of design options has increased dramatically. Instead of chips defaulting to... » 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

Optimizing Data Movement In SoCs And Advanced Packages


The amount of data that needs to move around a chip is growing exponentially, driven by the rollout of AI and more sensors everywhere. There may be hundreds of IP blocks, more compute elements, and many more wires to contend with. Andy Nightingale, vice president of product management and marketing at Arteris, talks about the demand for low-latency on-chip communication in increasingly complex ... » 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

Multi-Party Computation for Securing Chiplets


A new technical paper titled "Garblet: Multi-party Computation for Protecting Chiplet-based Systems" was published by Worcester Polytechnic Institute. Abstract "The introduction of shared computation architectures assembled from heterogeneous chiplets introduces new security threats. Due to the shared logical and physical resources, an untrusted chiplet can act maliciously to surreptitiousl... » read more

Thermally Aware Chiplet Placement Algorithm Based on Automatic Differentiation (MIT, IBM)


A new technical paper titled "DiffChip: Thermally Aware Chip Placement with Automatic Differentiation" was published by researchers at MIT and IBM. Abstract "Chiplets are modular integrated circuits that can be combined to form a larger system, offering flexibility and performance enhancements. However, their dense packing often leads to significant thermal management challenges, requiring ... » read more
