Abstract
A system and method of performing model-based refinement of a placement of components in integrated circuit generation select one of the components as a candidate component and postulate a move of the candidate component from an original position to a new position. The method includes defining nets associated with the candidate component. An initial perimeter and a new perimeter associated with each of the one or more nets are defined. The initial perimeter includes the candidate component at its original position and the new perimeter includes the candidate component at its new position. The method includes quantifying a change from the initial perimeter and the new perimeter and the original position and the new position, and obtaining a model of wires interconnecting the candidate component to the components of each of the nets. A result of the placement is provided for manufacture of the integrated circuit.
