3D Heterogenous Integration: Design And Verification Challenges


Next-generation semiconductor products increasingly rely on vertical integration technologies to drive system density, speed, and yield improvement. Due to the increased coupling effects across multiple physics, co-simulation and co-analysis of these phenomena are critical for a robust chip-package-system design. Advanced 2.5D/3D-IC systems are constructed with multiple dice, interposers, packa... » read more

Vision Transformers Change The AI Acceleration Rules


Transformers were first introduced by the team at Google Brain in 2017 in their paper, "Attention is All You Need". Since their introduction, transformers have inspired a flurry of investment and research which have produced some of the most impactful model architectures and AI products to-date, including ChatGPT which is an acronym for Chat Generative Pre-trained Transformer. Transformers a... » read more

Thermal Warpage Simulation Of A Temperature-Dependent Linear Elastic Material Package


The shift to advanced packaging in 3D and 2.5D IC design is making the numerical analysis of thermal warpage in electronic devices a crucial part of the design process. A reliable numerical tool enables the designer to perform early design analysis that accurately predicts warpage, thereby shortening the design process. The Cadence Celsius Thermal Solver integrated within the Cadence IC, pac... » read more

Research Bits: November 6


Fast superatomic semiconductor Researchers from Columbia University created a fast and efficient superatomic semiconductor material based on rhenium called Re6Se8Cl2. Rather than scattering when they come into contact with phonons, excitons in Re6Se8Cl2 bind with phonons to create new quasiparticles called acoustic exciton-polarons. Although polarons are found in many materials, those in Re6Se... » read more

Research Bits: October 24


Photonic-electronic hardware processes 3D data Researchers from the University of Oxford, University of Muenster, University of Heidelberg, and University of Exeter are developing integrated photonic-electronic hardware capable of processing three-dimensional data, which the team claims boosts data processing parallelism for AI tasks. The researchers added an extra parallel dimension to the... » read more

Research Bits: October 17


High-entropy multielement ink semiconductors Researchers from Lawrence Berkeley National Laboratory and UC Berkeley developed a high-entropy semiconducting material called ‘multielement ink’ that can be processed at low-temperature or room temperature. “The traditional way of making semiconductor devices is energy-intensive and one of the major sources of carbon emissions,” said Pei... » read more

Latency Considerations For 1.6T Ethernet Designs


Since its 1980s debut with 10Mbps shared LANs over coaxial cables, Ethernet has seen consistent advancements, now with the potential to support speeds up to 1.6Tbps. This progression has allowed Ethernet to serve a wider range of applications, such as live streaming, Radio Access Networks and industrial control, emphasizing the importance of reliable packet transfer and quality of service. With... » read more

RISC-V Wants All Your Cores


RISC-V is no longer content to disrupt the CPU industry. It is waging war against every type of processor integrated into an SoC or advanced package, an ambitious plan that will face stiff competition from entrenched players with deep-pocketed R&D operations and their well-constructed ecosystems. When Calista Redmond, CEO for RISC-V International, said at last year's summit that RISC-V w... » read more
