Abstract
A method of automatically selecting object size in an integrated circuit includes the steps of providing a circuit topology having objects disposed therein, inputting equations associated with the objects to provide sizing adjustment for the objects, assigning parameter values in the equations based on physical constraints of the circuit for one or more objects, selecting one or more objects to be sized, evaluating cones of influence for the objects selected to identify influenced objects influenced by a change in the selected object and computing for each selected object and influenced objects, a size in accordance with the associated equation until a user defined criteria is achieved for the circuit. A system for performing the method of the present invention is also described.
