Innovative practices session 4C: Disruptive solutions in the non-digital world

Achieving automotive quality requires IC tests that achieve 100% coverage of potential defects. With new cell-aware digital test pattern generation techniques and the simple stuck-at fault model, this has proven practical for digital circuitry, but there is no equivalent for mixed-signal circuitry. A simple but realistic analog defect model is described, based on industrial observations and theory. It is consistent with previous proposals, but has novel differences that make it suitable for schematic and layout-extracted netlists and more efficient to simulate. A couple of examples show its effectiveness.
