Abstract
Systems and methods are disclosed herein to provide techniques for providing programmable identification codes (IDCODE) for PLDs. For example, in accordance with an embodiment of the present invention, a programmable logic device includes a first non-volatile memory adapted to store a first identification code of the programmable logic device, and a second memory adapted to store a second identification code of the programmable logic device. A control circuit selects between the first identification code stored in the first non-volatile memory and the second identification code stored in the second memory to provide as an identification code for the programmable logic device.
