Santa Clara, Calif. | EcoPulse24
NVIDIA announced today a major expansion of its NVIDIA Agent Toolkit for engineering, adding re-architected NVIDIA PhysicsNeMo™ libraries and updated NVIDIA CUDA-X™ libraries as agent-ready tools designed to transform how products, chips and complex engineering systems are designed and developed.
The company said the expanded toolkit enables software developers to build autonomous AI engineers capable of applying AI physics skills, running accelerated engineering solvers and performing quantum chemistry simulations across increasingly complex engineering workflows.
NVIDIA also announced that NVIDIA Nemotron™ 3 Ultra now leads among open models in agentic register-transfer level (RTL) coding using the ACE-RTL hardware-design agent developed by NVIDIA Research, providing enterprises with a customizable foundation for AI-powered chip design and verification.
According to NVIDIA, industry leaders including Cadence, Siemens, Synopsys and other engineering software companies are already deploying NVIDIA accelerated computing and agentic AI technologies to advance autonomous engineering workflows spanning chip architecture, verification, advanced packaging and complete system development.
AI Engineers Designed for Modern Engineering Complexity
NVIDIA said designing the next generation of semiconductor devices and computing systems increasingly requires engineering teams to connect physics, simulation and performance analysis across highly complex design cycles.
To address that challenge, the company said a new generation of autonomous AI engineers is emerging that can operate specialized engineering tools, execute simulations and generate high-fidelity engineering data to help scale chip design, verification, packaging and systems engineering.
To support that transition, NVIDIA has re-architected PhysicsNeMo into agent-friendly software libraries and expanded the Agent Toolkit with new and updated CUDA-X libraries.
PhysicsNeMo provides AI physics capabilities for training and deploying physics-based AI models, while CUDA-X introduces accelerated engineering solvers together with quantum chemistry capabilities into agentic engineering workflows.
"Engineering has reached an inflection point. AI can now work with tools of physics, simulation and design," said Timothy Costa, Vice President and General Manager of Computational Engineering at NVIDIA.
"With NVIDIA Agent Toolkit, developers can build agentic engineers that reason using physics, run complex simulations and generate high-fidelity data to become a new engine for innovation in chip and system design."
NVIDIA Agent Toolkit Adds AI Physics and Accelerated Computing
NVIDIA said the Agent Toolkit enables developers to build specialized engineering AI assistants connected to domain-specific models, engineering tools and enterprise data.
With the addition of PhysicsNeMo and CUDA-X libraries, engineering agents gain access to AI physics models, accelerated numerical solvers and quantum chemistry capabilities for semiconductor, systems and industrial engineering.
What is NVIDIA Agent Toolkit?
NVIDIA Agent Toolkit is a software development framework that enables developers to build specialized AI agents capable of performing engineering tasks rather than simply answering questions. These AI agents can connect to engineering software, simulation tools, AI models and enterprise data to assist with chip design, verification, industrial engineering and scientific computing workflows.
With the latest expansion, the toolkit now incorporates NVIDIA PhysicsNeMo™ libraries for AI physics modeling and updated NVIDIA CUDA-X™ libraries, allowing AI agents to apply physics-based reasoning, execute accelerated numerical simulations and perform quantum chemistry calculations. According to NVIDIA, the platform is designed to help developers build autonomous AI engineers that can support increasingly complex engineering and semiconductor design processes.
AI Physics Skills
PhysicsNeMo libraries allow AI agents to train and deploy customizable AI physics models for complex simulation and engineering tasks while converting model architectures into callable tools that can be integrated into engineering workflows.
Iterative Sparse Solvers
The newly introduced NVIDIA cuISS (CUDA Iterative Sparse Solvers) library accelerates large sparse linear systems commonly used in engineering and physics simulations.
NVIDIA said the library is optimized for GPU flexibility and performance through modern composable solvers and preconditioners that enable developers to build scalable production-grade simulation engines for autonomous engineering workflows.
Direct Sparse Solvers
The NVIDIA cuDSS (CUDA Direct Sparse Solvers) library accelerates complex sparse linear systems that are central to electronic design automation (EDA) and scientific simulation.
The company said cuDSS provides high numerical robustness and performance for device, circuit and system simulations while scaling across multi-GPU and multi-node production deployments.
Quantum Chemistry
The new NVIDIA cuEST (CUDA Electronic Structure Theory) library brings high-accuracy quantum chemistry simulations to device-relevant scales.
According to NVIDIA, cuEST enables both density functional theory (DFT) and post-DFT methods to be integrated into production engineering workflows while supporting a broad range of modern functionals and making increasingly large ground-state and excited-state simulations practical on NVIDIA GPUs.
Nemotron 3 Ultra Advances AI Coding for Semiconductor Design
NVIDIA said semiconductor development depends on specialized register-transfer level (RTL) coding that requires high accuracy, deep engineering expertise and deployment flexibility.
Using ACE-RTL, an autonomous hardware-design agent developed by NVIDIA Research, NVIDIA Nemotron 3 Ultra now leads among open models in agentic RTL coding across the comprehensive Verilog design problems benchmark.
The company said Nemotron 3 Ultra combines industry-leading accuracy and efficiency while allowing enterprises to post-train models using proprietary datasets and deploy them locally or on premises to maintain greater customization, operational control and data privacy.
Developers can begin using Nemotron 3 Ultra through:
-
Cadence's harness
-
Synopsys' fully autonomous long-running design verification and analog/mixed-signal agents
-
Siemens' Questa One smart verification agentic toolkit
-
Hugging Face
