Abstract

A floorplanning method for an analog integrated circuit layout is disclosed. A first-type block is defined as a movable and deformable block with rectangle constraint, and a second-type block is defined as a fixed-size block without rectangle constraint. Each block in the floorplan is classified to the first-type or the second-type block. In a shape determination stage, a target shape is determined among candidates of the first-type block, the first-type block accordingly being modified to the target shape, resulting in at least one overlap in the floorplan. In an overlap elimination stage, neighboring blocks of each said overlap are analyzed, the overlap being then eliminated by utilizing surrounding space, resulting in unused space in the floorplan. In an enlargement stage, the unused space is utilized for enlarging the first-type block.
