Abstract
In accordance with an embodiment of the present invention, a programmable logic device includes configuration memory to store configuration data to configure the programmable logic device, and a non-volatile memory to store configuration data for transfer to the configuration memory to configure the programmable logic device. The non-volatile memory also stores a first code value based on the configuration data stored in the non-volatile memory. A code block calculates a second code value based on the configuration data transferred to the configuration memory. A comparator compares the first code value to the second code value to verify that the configuration data was not corrupted during the transfer from the non-volatile memory to the configuration memory.
