Abstract
Macro-cells in the integrated circuits (IC) design are large blocks which can be viewed as black-boxes. The logic and electronic behavior of these macro-cells are given but the inside structural description may or may not be known. As a consequence, macro-cells may have flexible geometries and pins of macro-cells can be located inside the block. The sizes of macro-cells are much larger than the sizes of standard-cells. A typical macro-cell could have a size being several percent of the whole placement area. Macro-cells are usually divided into two categories: soft macro-cells and hard macro-cells. Soft macros can have several possible specified shapes while hard macros have only one fixed geometry.
