True 3D-IC Problems


Placing logic on logic may sound like a small step, but several problems must be overcome to make it a reality. True 3D involves wafers stacked on top of each other in a highly integrated manner. This is very different from 2.5D integration, where logic is placed side-by-side, connected by an interposer. And there are some intermediate solutions today where significant memory is stacked on l... » read more

Easy-To-Use Reliability Checks Throughout The Design Cycle From IP To Full-Chip Tapeout


By Hossam Sarhan and Alexandre Arriordaz With the increasing complexity of design layouts and shorter tapeout cycles, waiting until signoff verification is no longer practical for design teams. There is a constant push to shift targeted verification activities “left” to earlier stages in the design flow. Finding and eliminating selected errors earlier during design and implementation, wh... » read more

Pre-Layout, Post-Layout Circuit Reliability


With the increasing complexity of design layouts and shorter tapeout cycles, waiting until signoff verification to check design reliability is no longer practical for design teams. Designers must now apply reliability verification checks throughout the design flow, from intellectual property (IP) level to full-chip level, to ensure they meet tapeout schedules while confirming design reliability... » read more

Blog Review: April 26


Codasip's Tora Fridholm introduces the NimbleAI project, an effort to design a neuromorphic sensing and processing 3D integrated chip that implements an always-on sensing stage, highly specialized event-driven processing kernels and neural networks to perform visual inference of selected stimuli using the bare minimum amount of energy. Synopsys' Anjaneya Thakar discusses computational lithog... » read more

IC Security Issues Grow, Solutions Lag


Experts at the Table: Semiconductor Engineering sat down to talk about the growing chip security threat and what's being done to mitigate it, with Mike Borza, Synopsys scientist; John Hallman, product manager for trust and security at Siemens EDA; Pete Hardee, group director for product management at Cadence; Paul Karazuba, vice president of marketing at Expedera; and Dave Kelf, CEO of Breker V... » read more

Using AI To Improve Metrology Tooling


Virtual metrology is carefully being added into semiconductor manufacturing, where it is showing positive results, but the chip industry is proceeding cautiously. The first use of this technology has been for augmenting existing fab processes, such as advanced process control (APC). Controlling processes and managing yield generally do not require GPU processing and advanced algorithms, so t... » read more

Thermal Integrity Challenges Grow In 2.5D


Thermal integrity is becoming much harder to predict accurately in 2.5D and 3D-IC, creating a cascade of issues that can affect everything from how a system behaves to reliability in the field. Over the past decade, silicon interposer technology has evolved from a simple interconnect into a critical enabler for heterogeneous integration. Interposers today may contain tens of dies or chiplets... » read more

Unblocking The Full Potential Of PCIe Gen6 With Shared Flow Control


As technology advances at a rapid pace, PCI Express (or PCIe) has grown tremendously, allowing data transfer up to 64 GT/s in Gen6. This technology is widely used in data centers, artificial intelligence and machine learning computing, high-performance computing accelerators, and high-speed applications—including high-end SSDs, automotive, IoT, and mil-aero. To fully utilize this high-spee... » read more

RISC-V Driving New Verification Concepts


Semiconductor Engineering sat down to discuss gaps in tools and why new methodologies are needed for RISC-V processors, with Pete Hardee, group director for product management at Cadence; Mike Eftimakis, vice president for strategy and ecosystem at Codasip; Simon Davidmann, founder and CEO of Imperas Software; Sven Beyer, program manager for processor verification at Siemens EDA; Kiran Vittal, ... » read more

Effective Resource Utilization In PCIe Gen6: Shared Flow Control


In PCIe 6.0, the data rate has doubled from 32 GT/s to 64 GT/s. This technology is a cost-effective and scalable interconnect solution that will continue to impact data-intensive markets and applications while maintaining backward compatibility with all previous generations of PCIe. Data-intensive uses include data centers, artificial intelligence/machine learning computing, high-performance co... » read more
