  • Patent number: 8181139
    Abstract: In one embodiment of the invention, a computer-implemented method of configuring a programmable logic device (PLD) includes placing logical functions within logical resources of the PLD to implement a desired netlist; swapping the logical function of at least one logical resource with the logical function of at least one other logical resource within the PLD; and evaluating whether to accept or reject the swap using a simulated annealing process that calculates at least three cost function values based upon routing priority groups, timing priority groups, and a timing critical group.
