Abstract
In one embodiment, a method of verifying a programming operation of a programmable logic device includes storing in non-volatile memory within the programmable logic device configuration data and a pre-calculated code value based on the configuration data. The method further includes transferring the configuration data from non-volatile memory to configuration memory within the programmable logic device; calculating a code value based on the configuration data transferred from the non-volatile memory to the configuration memory; and comparing the calculated code value to the pre-calculated code value.
