Hyperconvergence Of Design For Test And Physical Design


By Sri Ganta and Hyoung-Kook Kim In today’s highly competitive semiconductor industry, chip-design companies strive for competitive advantages by optimizing designs for PPA (Power, Performance, Area). Along with the functional logic, design cores also comprise DFT (Design for Test) logic that spreads across the design. The DFT logic also must be optimized for PPA, requiring design implemen... » read more

Challenges And Outlook Of ATE Testing For 2nm SoCs


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
