Abstract
In one embodiment, a programmable logic device includes a first multiplexer; a first memory adapted to store an identification code of the programmable logic device; and a second memory adapted to store an identification code of the programmable logic device. Inputs of a second multiplexer are coupled to the first memory and the second memory, and an output of the multiplexer is coupled to an input of the first multiplexer. The second multiplexer is adapted to select between the identification code stored in the first memory and the identification code stored in the second memory to provide the selected identification code to the first multiplexer.
