DOI: 10.1109/tvlsi.2022.3224361
Abstract: Path selection procedures identify path delay faults whose tests detect small delay defects. Path selection criteria are positive in the sense that they point to paths that should be selected, e.g., the longest paths. However,… read more here.

DOI: 10.3390/app152312560
Abstract: To solve the timing uncertainty in low-voltage circuits, this paper proposes an analytical sequential path delay model based on the lognormal distribution. Unlike previous works that primarily focus on combinational logic, our model provides a… read more here.
