AI-Powered VLSI Design

Celvvio integrates AI & ML at every stage of the design flow — faster iterations, fewer bugs, better silicon

RTL & Synthesis

AI-Assisted RTL Optimization

ML models predict timing violations before synthesis runs. Auto-suggest clock gating, pipeline restructuring & area reduction — cutting synthesis iterations by 40–60%.

Verification

Intelligent UVM Testbench Generation

LLM-driven UVM agent & sequence generation from protocol specs. Automated coverage-hole detection and constraint randomization targeting — reaching 95%+ coverage faster.

Physical Design

ML-Driven Floorplan & Placement

Reinforcement learning models guide floorplan decisions. AI-predicted DRC hotspots before full DRC runs — reducing signoff iterations from weeks to days.

Analog Design

AI-Aided Circuit Sizing

Bayesian optimization for analog circuit parameter tuning. Automated Monte Carlo analysis with smart corner selection — achieving spec closure 3× faster than manual methods.

Documentation

LLM-Powered Design Docs

Auto-generate datasheets, design specs, and test plans from netlists and simulation results. Reduces documentation effort by 70% — always accurate, always up to date.

Signoff

Predictive Signoff Analytics

AI models trained on past tapeout data predict IR drop, EM violations, and yield issues early. First-pass signoff success rate improved — fewer costly re-spins.
