FPGA-based SFL is a soft intellectual property (IP) core within the FPGA that bridges the JTAG
and flash interfaces. The SFL mega-function is available from Quartus II software.
Figure 3-8
shows the programming method when adopting a SFL solution
Please refer to Chapter 9: Steps of Programming the Quad Serial Configuration Device for the
basic programming instruction on the serial configuration device
