corner analysis (extended)

**Corner analysis (extended)** expands **traditional PVT evaluation** to include additional stressors like humidity, aging, and supply droop — ensuring robust operation beyond nominal corners for automotive and safety-critical applications. **What Is Extended Corner Analysis?** - **Definition**: PVT analysis plus additional stress factors. - **Extensions**: Humidity, aging, supply droop, radiation, mechanical stress. - **Purpose**: Comprehensive robustness verification. **Additional Corners**: High humidity/high temperature (H3TH), aging corner (threshold shifts after years), supply droop (SDF), radiation (total dose, single event), mechanical stress. **Why Extended Corners?**: Automotive environments (humidity, temperature extremes), long lifetime products (aging effects), safety-critical (must handle all stressors), harsh environments (radiation, vibration). **Analysis**: Simulate at extended corners, verify functionality and performance, ensure adequate margins, document worst-case behavior. **Applications**: Automotive (AEC-Q100), aerospace, medical devices, industrial controls, long-life products. Extended corner analysis is **future-facing stress test** — certifying chips for safety-critical applications by verifying operation under all conceivable stress combinations.
