binning by performance
**Binning by performance** is the **post-test classification of chips into product grades based on measured speed, power, and leakage characteristics** - it converts natural process variation into a structured pricing and product-segmentation strategy.
**What Is Performance Binning?**
- **Definition**: Assigning tested die to frequency or efficiency tiers according to validated operating limits.
- **Typical Bin Axes**: Maximum stable clock, leakage current, voltage requirement, and thermal behavior.
- **Operational Flow**: Wafer sort and final test data feed automated bin assignment logic.
- **Business Role**: Enables one physical design to serve multiple market SKUs.
**Why It Matters**
- **Revenue Optimization**: Highest-performing die are sold into premium bins with better margin.
- **Yield Monetization**: Near-miss die still create value in lower performance bins.
- **Inventory Flexibility**: Bin mix can be tuned to demand across product segments.
- **Feedback Loop**: Bin distribution exposes process drift and design sensitivity.
- **Customer Targeting**: Different use cases receive matched power-performance products.
**How Teams Run Binning Programs**
- **Limit Definition**: Build bin thresholds from characterization, reliability, and market needs.
- **Test Calibration**: Ensure measurement repeatability so bin boundaries remain trustworthy.
- **Economic Tuning**: Periodically adjust thresholds to maximize total gross margin and shipment goals.
Binning by performance is **a core bridge between silicon physics and product economics** - when executed well, it captures value across the full variation distribution instead of treating all non-premium die as loss.
