WebThis study describes an efficient design methodology from an industrial perspective on utilizing Register Transfer Level (RTL) coding style, full scan chain implementation and Automatic Test Pattern Generation (ATPG) to achieve a high percentage of testability in the final Integrated Circuit (IC). Web- Faults are tested by other test methods, for example, MBiST might cover logic close to memories. So the coverage can be computed without taking into account these faults; the ratio of ... i.e. the position of the failing scan cell in the scan chain. ATPG tools allow dumping for every scan chain the design names of the included scan cells; with
