3.1. Avalon-ST Configuration
The Avalon® -ST configuration scheme replaces the FPP mode available in earlier device families. Avalon® -ST is the fastest configuration scheme for Intel® Stratix® 10 devices. This scheme uses an external host, such as a microprocessor, MAX® II, MAX® V, or Intel® MAX® 10 device to drive configuration. The external host controls the transfer of configuration data from external storage such as flash memory to the FPGA. The logic that controls the configuration process resides in the external host. You can use the PFL II IP with a MAX® II, MAX® V, or Intel® MAX® 10 device as the host to read configuration data from the flash memory device and configure the Intel® Stratix® 10 device. The Avalon® -ST configuration scheme is called passive because the external host, not the Intel® Stratix® 10 device, controls configuration.
