ONE ANALOG DESIGN PER DAY

 A global IC market leader engaged our team. Our task is to port a 2.5 GHz voltage-controlled oscillator (VCO) from one process node to another. The mandate was to improve power, performance, and area (PPA) while maintaining the original phase noise specification, a critical figure of merit for RF applications. 

• Technology porting: Transition the VCO design between nodes without compromising performance.
• PPA optimization: Reduce power and area under tight design constraints.
• Spec integrity: Preserve phase noise, a highly sensitive metric.
• Time-to-market: Achieve results faster than traditional design cycles.

We applied our AI-powered analog design flow, combining ML-based circuit modeling, rapid dataset generation, and automated optimization. The workflow included:

1. Circuit porting from the legacy node.
2. Dataset generation and model training using our proprietary neural network architecture.
3. AI-based optimization loop targeting PPA while enforcing phase noise constraints.
4. Self-tuning enhancement to guarantee PVT robustness.

• One Analog Design per Day: Porting, dataset generation, ML model building, and optimization completed in 10 hours.
• Simulation acceleration: Achieved a 19,000× speedup over SPICE-like simulators (breaking our previous record of 8,000×).

• 20% power reduction. 
• 40% area reduction. 
• Achieved in just 6 minutes of AI-based optimization.
   

• Integrated self-tuning technology for real-time re-centering. 
• Delivered ±1% variation in center frequency and power consumption across the full PVT range.
• Achieved with minimal circuit area overhead.

•  Faster Time-to-Market: Reduced VCO design cycle from weeks to hours.
• Superior PPA: Significant reduction in power and area while holding phase noise constant and 1% spec variation over PVT range.
• Silicon Reliability: Self-tuning ensured long-term spec compliance across manufacturing and environmental variations.
• Competitive Edge: Customer gained a high-performance, compact VCO ready for integration into next-generation IC products.

 This case study demonstrates how our AI-driven design methodology not only automates process-node porting but also sets new benchmarks in speed, PPA optimization, and robustness—making “one analog design per day” a practical reality. .
