Why Analog And Mixed-Signal Chips Resist Adaptive Test


Key Takeaways Analog and mixed-signal test remains heavily specification-based because the measurements do not always produce a single expected result. The absence of objective coverage metrics has historically encouraged conservative test flows, which IEEE 2427-2025 begins to address. Separating device behavior from test-path variation is a prerequisite for any adaptive flow—and h... » read more

Co-Packaged Optics Testing Faces Steep Data Center Ramp


Key Takeaways: Device interface board must balance flexibility in handling with customization for different optical connectors. Test fixtures should account for DUT socketing challenges, such as warpage, coupling, and interference. Advanced data management practices will help speed yield learning. Integrating photonic and electrical ICs into co-packaged optics (CPO) requires... » read more

Lam Research established a panel-level packaging cen... » read more

Test Distribution Evolves To Meet AI Challenges


The proliferation of artificial intelligence (AI) is driving rapid acceleration of the semiconductor market, which analysts now predict will reach $1 trillion this year. Many semiconductor devices will be the GPUs that populate the data centers that run AI workloads. Driven by strong, sustained investments from hyperscaler operators, high-performance computing (HPC)/AI data centers are expected... » read more

AI Accelerator Testing Depends On DFT Innovations


Key Takeaways: I/O and lane repair capabilities are becoming critical to improving yield. System-level testing catches marginal defects and rare defects such as silent data corruption errors. 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

Smart Test Collides With The Data Chain


Key Takeaways: The promise of smart test is a data-chain problem before it is an algorithm problem. A device can pass every checkpoint and still carry a latent defect the test record never captured. As test grows more adaptive, the validity of the measurement environment matters as much as the measurement itself. For years, the test roadmap has pointed toward more adaptive f... » read more

Chip Industry Week in Review


Advanced nodes and capacity The US Commerce Dept. told IC equipment makers to stop shipments to Hua Hong Group, China's No. 2 chipmaker, in order to protect America's lead, according to Reuters. Global AI competition is causing wafer and packaging shortages, but capacity increases are expected to come online later this year and in 2027 to ease the crunch, according to TrendForce. Leadi... » read more

AI Accelerators Usher In New Era For IC Test


Key Takeaways The parallelism in AI accelerators enables low latency but complicates failure isolation. HBM can account for 50% of package cost, so known-good stack assurance is critical. DFT and test cooperate to solve final test, singulated die test, SLT, and in-system test for data centers. AI accelerators are used for everything from training large language models to mak... » read more
