Control-block based device vs. SDM-based device - Control-block based device vs. SDM-based device What are differences between Control-block based device and SDM-based device? Replies: Re: Control-block based device vs. SDM-based device Hello, SDM(Secure Device Manager) is controller which integrates high security features(Authentication + Encryption) during FPGA configuration. This is implemented in new devices such as Stratix 10 series and all Agilex series FPGAs. link: https://www.intel.com/content/www/us/en/docs/programmable/683458/current/device-configuration-and-secure-device.html Control block base is a normal device configuration flow, without high security features(compare to SDM). This is implemented in older devices such as Cyclone V series, Cyclone 10 series and Stratix V series FPGAs. link: https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-guidance/configuration-support.html regards, Farabi
