摘要： A multi-row standard cell and an integrated circuit (IC) structure using the standard cell are provided. The IC structure includes a plurality of cell rows extending in a first direction. At least two cell rows of the plurality of cell rows have different row heights. The IC structure includes a multi-row standard cell positioned in two or more cell rows having different row heights. At least one active region is shared by portions of the multi-row cell across the at least two cell rows. The IC structure may also include one or more asymmetric shared power rails disposed in an asymmetric manner across a row boundary between the at least two cell rows of different row heights. The multi-row standard cells and IC structures allow placement of multi-row cells for mixed track height arrangements in a manner not limited to multiples of row heights.
