A.3.3. Secure Device Manager

The key component of the security architecture of Intel Agilex 5 FPGAs is the Secure Device Manager (SDM). Robust security technologies are integrated within the SDM to help ensure data integrity and facilitate secure boot, configuration, and operation of the device.

The SDM always boots first and is responsible for locating and securely loading the configuration bitstream. The configuration bitstream only includes the HPS FSBL, which the SDM copies to the HPS and releases the HPS from reset. The HPS is responsible for securing subsequent boot stages, and may use services from the SDM to assist in HPS Secure Boot. Finally, the SDM also controls access to HPS debug.
