7.2. Intel Agilex® 7 Configuration Architecture Overview
Intel Agilex® 7 devices employ configuration architecture that is quite similar to the Intel® Stratix® 10 architecture. The Secure Device Manager (SDM), a dedicated hard processor, controls and monitors all aspects of device configuration from device power-on reset. This configuration architecture is different from earlier Intel FPGA device families where state machines control configuration.
There are important differences between Intel Agilex® 7 and Intel® Stratix® 10 devices and previous device families with respect to available configuration modes, configuration pin behavior, and connection guidelines. In addition, the bitstream format is different. Knowing about these differences and how these pins behave can help you understand and debug configuration issues.
