You find respective configuration schematics in the FPGA device handbooks. My suggestion is the scheme "Programming Serial Configuration Devices In-System Using the JTAG Interface" which uses only a JTAG header and programs the AS memory through JTAG. Alternatively, you have the "Combining JTAG and AS Configuration Schemes" with separate AS and JTAG headers.
