Abstract
An automated method and apparatus for positioning gate array circuits in an integrated circuit design. An initial integrated circuit design includes logic cells and gate array fill circuits positioned thereon. The gate array fill circuits are positioned in available space between the adjacent logic cells so as to fill the available space with the maximum gate array fill circuits. A gate array logic element to be positioned in the integrated circuit design, such as may be required by an engineering change to the circuit design, is automatically positioned between adjacent logic cells so as to allow for full utilization of any space remaining between the adjacent logic cells by gate array fill circuits.
