Abstract
A method and apparatus for efficiently selecting cells within a circuit design database. The invention includes four primary features for selecting cells including (1) selecting only those cells that are in a pre-identified region and within a pre-identified selection area; (2) maneuvering through the circuit design hierarchy and selecting cells or regions at selected levels of hierarchy by using predetermined up and down hot-keys; (3) sorting selected cells by instance name, and manually selecting a desired cell or region from the resulting sorted list; and (4) sorting selected cells by a corresponding net name, and manually selecting a desired cell or region from the resulting sorted list.
