Abstract

In a method for placement of components for a VLSI circuit, control signal connection networks and data signal connection networks are identified. Then, an initial placement of the components for the VLSI circuit is made. This initial placement is iteratively improved. The algorithm used for the iterative improvement has a cost metric in which a horizontal component for length of a connection network and a vertical component for length of the connection network are weighted differently dependent on whether the connection network was identified as a control signal connection network or a data signal connection network. The different weighting results in improved regularity of the placement of data path components and thus a more efficient routing of connection networks between the components.
