Time to value

Quick Setup (< 1 hour)

You can use SigmanticAI to accelerate semiconductor chip design by generating synthesizable RTL and verification testbenches directly from natural language specifications. The tool connects directly with existing EDA simulators like VCS, Questa, and Xcelium to run simulations, debug hardware failures, and inspect waveform traces automatically. Engineers can collaborate with interactive specialist agents to modify registers, create UVM testbenches, and write SVA assertions, or set autonomous background tasks to iteratively close code coverage. It runs locally without storing proprietary chip design data or customer IP.
