Abstract
Systems and methods for secure booting of secure programmable logic devices (PLDs) are disclosed. An example system includes a secure PLD including programmable logic blocks (PLBs) arranged in a PLD fabric of the secure PLD, and a configuration engine configured to program the PLD fabric according to a configuration image stored in a non-volatile memory (NVM) of the secure PLD and/or coupled through a configuration input/output (I/O) of the secure PLD to the configuration engine. The secure PLD is configured to retrieve a pre-authentication status associated with the configuration image from the NVM, determine or verify the retrieved pre-authentication status associated with the configuration image includes a valid status, and boot the PLD fabric of the secure PLD using the configuration image.
