Abstract :
IR-drop-induced malfunction is mostly caused by timing violations on activated critical paths during the capture cycle of at-speed scan testing. A critical-path-aware X-filling method is proposed for reducing IR-drop, especially on gates that are close to activated critical paths, thus effectively preventing test-induced yield loss.
