Abstract
A method for verifying that data is correctly loaded into an individual programmable logic device includes computing a reference digest of the data to be loaded into the individual programmable logic device, loading the data into the individual programmable logic device, computing inside the individual programmable logic device an as-programmed digest of the data that was loaded into the individual programmable logic device, reading the as-programmed digest out of the individual programmable logic device, comparing the as-programmed digest with the reference digest, and verifying the loaded data if the as-programmed digest matches the reference digest, and indicating an error if the as-programmed digest does not match the reference digest.
