    • A method of implementing a design on a programmable logic device (PLD) includes generating a database that identifies correspondence between resources and programming frames of the PLD. A first PLD design is compiled, wherein the first design uses a first set of resources in a first manner. Costs associated with using the first set of resources of the first design in the first manner are reduced. A second PLD design is then compiled, applying the reduced costs associated with using the first set of resources. A second set of resources required to compile the second design is identified, wherein the second set of resources is not used in the same manner as the first set of resources. A set of programming frames associated with the second set of resources is identified. Costs associated with using a third set of resources associated with the set of programming frames are increased.

    • An embodiment of the invention relates to an integrated circuit such as an FPGA wherein a stable unique identifier is produced by reading an intrinsic characteristic of the IC such as a physically unclonable function, and a related method. In one embodiment, a first unique identifier is generated using the intrinsic characteristic and is subdivided into a plurality of first subsets. A second unique identifier is received and subdivided into a plurality of second subsets. The first and second subsets are compared to identify matching subsets to generate the stable unique identifier. Each of the one or more matching subsets includes a particular one of the plurality of first subsets that matches a corresponding one of the plurality of second subsets. The stable unique identifier can be integrated into logic of the IC. Prior to comparing the subsets, the first and second subsets can be transformed with one-way functions.

    • A programmable logic device (PLD) includes a die having first and second bond pads, each being weakly pulled to a first voltage. A package enclosing the die has an external pad configured to receive a second voltage. A conductor couples one and only one of the first and second bond pads to the external pad, such that one bond pad is pulled to the first voltage, and the other bond pad is pulled to the second voltage. A logic circuit on the die is coupled the first and second bond pads. The logic circuit enables the PLD to be configured in response to a first type of bit stream if the first bond pad is pulled to the second voltage, and enables the PLD to be configured only in response to a second type of bit stream if the second bond pad is pulled to the second voltage. In another embodiment, a bond pad is weakly pulled to a first voltage, and can be connected or not connected to an external pin for applying a second voltage.
