Synopsys and TSMC developed a multi-die demo vehicle capable of full test, monitor, debug, and repair capability across the system’s lifecycle. The proliferation of accelerators in AI... » read more

Enhancing Silicon Reliability With In-System Test And SLM Data

By Adam Cron - 07 Apr, 2026 - Comments: 0

Innovation in semiconductor development and manufacturing shows no signs of slowing down. Ever-larger chips at ever-smaller geometries create new challenges all the time. At the same time, competitive pressures are shrinking time to market (TTM) and putting enormous pressure on project teams. Furthermore, the wide use of electronics in safety-critical applications demands better reliability, av... » read more

Chiplet Interfaces Embrace Failures

By Anne Meixner - 12 Aug, 2025 - Comments: 0

Redundancy in chiplet interfaces is now a prerequisite for achieving sufficient yield in high-performance computing devices, which today are packed with tens of thousands of interconnects. And as the number and density of those interconnects increases, the prospects for yield only worsen. For more than two decades, high-speed I/O interfaces have included reliability strategies to manage in-f... » read more

Challenges And Outlook Of ATE Testing For 2nm SoCs

By Sriharsha Vinjamury - 08 Aug, 2024 - Comments: 0

The transition to the 2nm technology node introduces unprecedented challenges in Automated Test Equipment (ATE) bring-up and manufacturability. As semiconductor devices scale down, the complexity of testing and ensuring manufacturability increases exponentially. 3nm silicon is a mastered art now, with yields hitting pretty high for even complex packaged silicon, while the transition from 3nm to... » read more

Are You Ready For HBM4? A Silicon Lifecycle Management (SLM) Perspective

By Faisal Goriawalla - 06 Aug, 2024 - Comments: 0

Many factors are driving system-on-chip (SoC) developers to adopt multi-die technology, in which multiple dies are stacked in a three-dimensional (3D) configuration. Multi-die systems may make power and thermal issues more complex, and they have required major innovations in electronic design automation (EDA) implementation and test tools. These challenges are more than offset by the advantages... » read more
