Abstract:
Various methods and apparatuses (such as computer readable media implementing the method) are described that relate to proximate placement of sequential cells of an integrated circuit netlist. For example, the preliminary placement is received; and based on the preliminary placement, a group of sequential cells is identified as being subject to improved power and/or timing upon subsequent placement. In another example, identification is received of a group of sequential cells subject to improved power and/or timing upon subsequent placement; and proximate placement is performed of the identified group of sequential cells. In yet another example, a proximate arrangement of a group of sequential cells is received; and if proximate placement fails, then the group of sequential cells is disbanded and placement is performed of the sequential cells of the disbanded group.
