摘要:
Some embodiments of the invention include apparatus, systems, and methods to force values to output nodes of registers of at least one circuit unit of a device during an idle state to reduce leakage power in the circuit unit. Other embodiments are described and claimed.
摘要:
The invention relates to a new method of guidance for routing of nets in an integrated circuit model wherein all nets are first approximately routed, as with Steiner routing, and victim nets with functional delay noise above predetermined thresholds are identified. Each victim net is then detail routed. For each victim net detail routed, a set of least noise aggressive neighboring nets is selected. Segments of those neighboring nets are assigned tracks adjacent to the victim net in such a way as to maximize utilization of the victim net's neighboring tracks, thereby reducing noise induced on the victim net and maximizing use of available space on the semiconductor. The process is then repeated until there are no additional victim nets, at which point the remaining nets are detail routed.
