Abstract
A cell apparatus and method for use in building complex integrated circuit devices. The cell apparatus and method for use in building complex integrated circuits includes a cell which has regions dedicated to specific types of circuit elements and a method for designing the cell. A first region within the cell is dedicated to a first type of circuit element. A second region within the cell is dedicated to a second type of circuit element. A third region is dedicated to one or more diverse types of integrated circuit elements for utilization in multiple diverse applications of integrated circuits. The cell can be utilized in conjunction with multiple cells to efficiently form an image representing a complex integrated circuit device. The cell includes an upper edge and a lower edge, a plane dedicated to a ground line, a plane dedicated to a clock line, and a plane dedicated to a voltage supply line. The first region within the cell can specifically be dedicated to n-type transistors and the second region to p-type transistors. A central region located within the cell divides the first region and the third region from the second region. The cell can be duplicated multiple times to build a library of dynamic logic cells such as those used in integrated circuit macros.
