NVIDIA has introduced new benchmark results showing Nemotron 3 Ultra as the leading open model for agentic register-transfer level (RTL) coding.
Combined with the ACE-RTL framework, the model achieved a 97.1% average pass rate across nine RTL coding categories on the Comprehensive Verilog Design Problems (CVDP) benchmark while using up to 71% fewer tokens per iteration than competing open models.
Built on a Hybrid Mamba-Attention Mixture-of-Experts architecture, Nemotron 3 Ultra is designed for long-context reasoning and integrates with major EDA platforms from Cadence, Siemens, and Synopsys to accelerate chip design and verification workflows.
