Siemens’ Heather George suggests adopting a shift-left strategy for complex designs that integrate multiple dies into a package and examines the challenges and opportunities for performing comprehensive tests on 2.5D and 3D IC designs.

Synopsys’ Shekhar Kapoor notes that when considering whether a system will perform as intended, techniques that work well for monolithic SoCs may not be as well suited for multi-die system architectures.

Cadence’s Anne-Marie Schelkens explains how computational fluid dynamics can help significantly improve the efficiency of drones and extend their flight time and range.

Coventor’s Timothy Yang investigates whether a physical vapor deposition and ion beam etch technique can lower resistance of semiconductor metal lines compared to a conventional trench etch followed by damascene deposition.

Riscure’s Jasper van Woudenberg explores how ChatGPT can be used in source code analysis by feeding it a C file with many known vulnerabilities, and finds that while it is not currently accurate enough to fully rely on for code review, it could be used as a tool as long as the security analyst understands its limitations.

Keysight’s Rick Clark notes that while co-packaged optics presents a revolution in a long unchanged approach to data center switch design, it carries with it an accompanying set of challenges: balancing power and cost savings, standardizing for interoperability, ensuring reliability and repairability, and implementing new methods for test and validation.

SEMI’s Jaegwan Shim shares highlights from the keynotes at SEMICON Korea, including the explosion of connected devices, 3D integration as a driver of higher performance, and semiconductor market outlooks.

Ansys’ Gwenael Moysan looks at optimizing automotive interior lighting through simulation of aspects such as light leakage, display legibility, and sun reflections.

Arm’s Andy Rose shares an overview of the company’s architecture security efforts, including defensive execution technologies, isolation technologies, platform security services, and standard security APIs, as well as the importance of ecosystem collaboration.

Lithography expert Chris Mack shares some updates on updates on EUV pellicles, plus metrology and other highlights from the recent SPIE Advanced Lithography and Patterning Symposium.
