Abstract: A method and semiconductor structure are provided for intermixing circuits of two or more different cell classes, such as standard cells and gate array cells, on a common chip or substrate with minimum gound rule separation between adjacent cells of different classes. Cell locations are defined with given boundaries and contiguously arranged on the surface of a semiconductor chip, and then either standard cell type or gate array type circuits are formed within any of the cell locations to provide a structure for balancing chip density and performance versus hardware turn-around-time.
