Abstract
A method for reducing leakage power of a logic network comprising the steps of: using (observability) don't care information to identify “sleep states” for individual nets; determining based on probabilistic analysis at least one net in which expected power consumption will be reduced by forcing a net to a particular value during at least a portion of a “sleep state”; and forcing the determined net to the determined value determined portion of that “sleep state”.
