What is ATPG and what are fault models?
ATPG is a software process that generates test vectors to detect manufacturing defects. Fault models abstract physical silicon defects into mathematical models (like stuck-at high/low) to help ATPG programs target specific failure modes.
Introduction to Automatic Test Pattern Generation (ATPG) Fault Models
Understanding the details of Automatic Test Pattern Generation (ATPG) Fault Models is essential for front-end verification, DFT testing, or backend timing closure in modern sub-micron silicon processes.
This daily knowledge byte offers concise definitions, architectural outlines, and practical design solutions to support your engineering career.
