Note: With the same steps outlined above, you can generate a .jbc or .svf file from the .jic file. Programming Serial Configuration Devices with the Quartus II Programmer You can use the Quartus II programmer to generate serial configuration device programming files. The Quartus II programmer can generate both .jic and .jam files with the factory default enhanced SFL image that is run directly from the Quartus II programmer. As long as the JTAG interface of the FPGA is accessible for programming, you can use the factory default enhanced SFL image that is run directly from the Quartus II programmer for your application. If you enable tamper protection in design security feature, JTAG configuration is disabled. However, the serial configuration device is still accessible from JTAG interface if the FPGA is configured with encrypted configuration image that contains Altera Serial Flash Loader IP core. Programming Serial Configuration Devices Using the Quartus II Programmer and .jic Files To program serial configuration devices with .jic files, you must perform the following steps: 1. When the .sof-to-.jic file conversion is complete, add the .jic file to the Quartus II programmer window: Using the Altera Serial Flash Loader IP Core with the Quartus II Software Send Feedback Altera Corporation 8 AN-370 2015.07.01 Programming Serial Configuration Devices Using the Quartus II... a.

Note: If the Program/Configure check boxes are not specified, the Quartus II programmer bypasses the request. Also, if the FPGA does not have the SFL image when the serial configuration device data is programmed via the JTAG interface, the programming process fails. You can program multiple serial configuration devices by including more than one .jic file in the Quartus II programmer. Note: Your FPGA must be in active serial configuration mode to enable the Altera Serial Flash Loader IP core to program. Programming Serial Configuration Devices Using the Quartus II Programmer and .jam Files When programming with .jam files, the Quartus II programmer requires configuring the FPGA and programming the serial configuration device in one step. To program serial configuration devices with .jam file, perform the following steps: 1. When the .jic-to-.jam file conversion is complete, add the .jam file to the Quartus II programmer window: a. In the Tools menu, select Programmer. The Chain1.cdf dialog box appears. b. Click Add File. In the Select Programming File dialog box, browse to the .jam file. c. Click Open. 2.
