Scan is a widely used design-for-testability technique to improve test and diagnosis quality, however, scan chain failures account for almost 50% of chip failures. In this paper, ...
Current paper presents new alternatives for accelerating the task of fault simulation for sequential circuits by hardware emulation on FPGA. Fault simulation is an important subta...
