126.96.36.199.1. Serial Configuration Devices
|1||If you want to use the AS configuration mode with large device densities, confirm there is a configuration device available that is large enough for your target FPGA density.|
Quad SPI flash devices are used as serial configuration devices in the AS configuration scheme.
Serial configuration devices can be programmed using a Intel® FPGA Download Cable II with the Intel® Quartus® Prime software through the active serial interface.
Alternatively, you can use supported third-party programmers such as BP Microsystems and System General, or a microprocessor with the SRunner software driver. SRunner is a software driver developed for embedded serial configuration device programming that designers can customize to fit in different embedded systems.
Serial configuration devices do not directly support the JTAG interface; however, you can program the device with JTAG download cables using the Intel® Agilex™ FPGA as a bridge between the JTAG interface and the configuration device, allowing both devices to use the same JTAG interface.
Programming the Quad SPI flash device from JTAG using the Intel® Agilex™ FPGA as a bridge is slower than using the standard AS interface.
