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.
