【应用笔记】AN370:在Quartus II软件中使用串行FlashLoader(AN 370: Using the Serial FlashLoader with the Quartus II Software)
Altera的串行FlashLoader(Serial FlashLoader, SFL)是第一个针对Altera串行配置器件的在系统编程解决方案，它使用JTAG接口。SFL解决方案在4.1SP1及以后版本的Quartus II软件中可以使用。
Using the JTAG interface, the Altera® Serial FlashLoader (SFL) is the first in-system
programming solution for Altera serial configuration devices. The SFL solution is
available with the Quartus® II software version 4.1 SP1 and later. The SFL
megafunction is available with the Quartus II software version 6.0 and later.
Because serial configuration devices do not support the JTAG interface, the
conventional method to program them is via the active serial (AS) programming
interface. With the AS programming interface, the configuration data used to program
serial configuration devices is downloaded via programming hardware.
However, with the SFL you can program serial configuration devices in-system via
the JTAG interface. To do so, use an FPGA as a bridge between the JTAG interface and
the serial configuration device.an370.pdf
