Abstract
High gate count integrated circuits (ICs) are designed in a heirarchical manner. In a first pass through a computer design system basic cells are composed to form one-level-up building block cells. In a second pass through the same computer design system the one-level-up building block cells are used as 'basic' cells and composed to form a two-level-up structure which may be a building block cell or a chip.
