WebIR-Drop Analysis The IR-drop on a gate is dynamic. Average IR-drop in a timing window is used. Start at the launch clock cycle. End point is chosen based on SPICE simulation. Make sure the IR-drop-induced delay is close enough to real dynamic case. 7 Dynamic IR-drop on a gate during the launch and capture cycles. Webpatterns under real workloads, designers perform dynamic IR drop simulation for several vectors, each spanning a few hundred thousand cycles. Therefore, IR drop analysis in industry is performed for a subset of switching patterns. This subset contains a small number of worst-case slices of all vectors, chosen by a vector proﬁling ﬂow, high school interview appearance
