In three-dimensional integrated circuits (3DICs), aggressive wafer-thinning can lead to large spikes in individual device temperatures. These "hotspots" must be carefully analyzed at design time to ensure that the device temperatures will not cause the circuit to malfunction, and to assess the device temperature's impact on the longevity of the circuit. In this paper we present a tool flow for capturing accurate per-transistor power values in standard cell designs to allow for detailed thermal analysis. After extracting power values, High Definition Power Blurring is used to analyze the thermal performance of the inter-chip communication bus of a "Cool Interconnect" chip.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
