1. A method for positioning components of a system onto a target device utilizing programmable logic devices (PLDs) that allows the system to satisfy timing constraints, comprising:

  • assigning an initial location for a user defined region, that includes a subset of components of the system, on the target device;

    moving the user defined region from the initial location to a second location where a second user defined region resides;

    moving the second user defined region from the second location to the initial location; and

    evaluating a cost function associated with the user defined region in the second location.
