Re: SFL image

Simply include the SFL instance to your top level design.

Re: SFL image

You don't them, unless you don't have other connections of your design to the AS memory. A typical instantiation looks like this: 

sfl_inst : sfl PORT MAP ( noe_in => '0' );

Re: SFL image

It's all in the device manuals, e.g. figure 10–30. programming serial configuration devices in-system using the jtag interface for Cyclone III.

Isee following errors when I disable Share ASMI interface option. 

 

Error: Pins ALTERA_DCLK both have the SPI-related DCLK Pin assignment, but only one pin can have this assignment 

Error: Pins ALTERA_SCE both have the SPI-related SCE Pin assignment, but only one pin can have this assignment 

Error: Pins ALTERA_SDO both have the SPI-related SDO Pin assignment, but only one pin can have this assignment 

Error: Pins ALTERA_DATA0 and ALTERA_DATA0 both have the SPI-related Data[0] Pin assignment, but only one pin can have this assignment
