AMS-RF test quality: Assessing defect severity.

Abstract

In safety critical applications there is a demand for estimating defect coverage in order to meet stringent quality levels. However, defect simulation of complex AMS-RF circuits is computationally expensive since achieving good confidence interval requires sampling many defects. In this paper, we show on a practical case of study that it may be beneficial to complement defect coverage with fault coverage and assess the severity of defect escapes to get a complete picture of test quality.
