Abstract

A method, system and program for reducing or optimizing leakage power consumption in an integrated circuit produced in accordance with an integrated circuit model. A fast corner timing database and configurable timing constraints are used in conjunction with hold cell logic to identify a set of cells that should not be modified. A leakage optimization procedure is responsive to a slow corner timing database and timing constraints for a slow corner. The procedure is configurable and includes the repair of register transition violations. The procedure is performed on a select number of paths before an adjusted timing slack value is determined and cells are addressed in response to the number of failing timing paths associated with a cell. Some embodiments generate information in a router compatible format that identifies a desired modification to the top-level integrated circuit design.
