Determining the cause of a problem. Also known as "fault diagnosis," the term may refer to hardware or software, but always deals with methods that can isolate the ...
ATPG targets faults at IC-gate boundaries, but 50% of defects are located within cells. Learn how cell-aware ATPG and user-defined fault models help to ferret out these hard-to-squash bugs.
Once IC fabrication is complete, engineers use fault models to create test patterns that detect defects. These fault models are typically abstractions of defect behavior based on our experience and ...
