Abstract
An integrated circuit (IC) design comprising a scan chain may be received, where stimulus values may be scanned-in and response values may be scanned-out through a scan path in the scan chain, where the scan path may include a first scan cell and a second scan cell such that the first scan cell is downstream with respect to the second scan cell. The scan chain may be modified to enable observation of a 0 and a 1 value in the first scan cell in presence of a defect in the second scan cell, or observation of a 0 and a 1 value in the second scan cell in presence of a defect in the first scan cell.
