Silicon Copilot

Silicon Copilot is an AI agent that speeds up pre-silicon chip verification. On a typical ~21-month SoC program, verification starts at architecture freeze and runs to tape-out, often needing several verification engineers per designer. Most of the early verification effort goes into reading specs, writing test plans, building testbenches and getting first tests running, and that work repeats on every block. Silicon Copilot targets that window. From a single command, the agent plans the work, reads the spec and RTL, and generates a verification test plan where every item defines its stimulus, checks and coverage. Each item carries a provenance tag and lineage back to the spec section or RTL signal it came from, so engineers can trust it and sign off. The plan then becomes testbench code, which is run in simulation with coverage reports and waveforms. In the demo, the agent takes an 8-bit UART from one command to a traceable test plan, testbench, simulation and coverage in minutes. Compressing this window lets RTL freeze and tape-out land about 3.5 months earlier, and frees engineers to focus on features and failure scenarios.
