Understand this story
On November 3, 2026, NVIDIA published an article stating that AI is driving semiconductor wafer fabs into the "AI-defined factory" stage, accelerating design, testing, and production decisions in chip manufacturing through accelerated simulation, learned physical models, AI agents, and digital twins. The cases cited in the article show that Applied Materials' ACE+ multiphysics platform, leveraging PhysicsNeMo, achieved up to 35x acceleration in topography simulation; Siemens, after integrating cuLitho into its Calibre lithography software, accelerated key simulation workloads by up to 17x; and COMSOL achieved up to 10x acceleration with cuDSS. NVIDIA stated that analysis tasks that originally took days can be compressed to minutes, but critical process changes still require high-precision simulation, experimental validation, and engineer review. Applied Materials also built a digital twin of an entire wafer fab based on NVIDIA Omniverse, simulating material flow and validating layout before production begins.

NVIDIA says AI accelerates chip factory simulation by up to 35x
NVIDIA published an article stating that AI is driving semiconductor wafer fabs into the "AI-defined factory" stage, accelerating design, testing, and production decisions in chip manufacturing through accelerated simulation, learned physics models, AI agents, and digital twins. Cases in the article show that Applied Materials' ACE+ multiphysics platform, with the help of PhysicsNeMo, achieved up to 35x acceleration in topography simulation; Siemens, after integrating cuLitho into its Calibre lithography software, achieved up to 17x speedup on key simulation workloads; and COMSOL achieved up to 10x speedup with cuDSS. NVIDIA says analysis tasks that originally took days can be compressed to minutes, but critical process changes still require high-precision simulation, experimental validation, and engineer review.

NVIDIA: AI Reshapes Chip Factories, Simulation Speeds Up by Up to 35x
NVIDIA says AI is driving semiconductor fabs into the "AI-defined factory" stage, accelerating chip manufacturing decisions through accelerated simulation, learned physics models, AI agents, and digital twins. Applied Materials' ACE+ platform uses PhysicsNeMo to achieve up to 35x acceleration in topography simulation, while Siemens Calibre, after integrating cuLitho, speeds up key simulation workloads by up to 17x. Applied Materials has also built a digital twin of an entire wafer fab based on NVIDIA Omniverse, simulating material flow and validating layouts before production begins.
