3.3. Creating Split RBF Images

After the Intel® Quartus® Prime FPGA project has been successfully compiled and a .sof configuration file has been generated, a pair of split .rbf files must be generated using the quartus_cpf command line utility. Use the -c option to indicate that this is a conversion step, and use the --hps option to indicate that the .rbf should be split into peripheral and core files. The remaining arguments are the input .sof file and the output .rbf file base name.

$ quartus_cpf --convert --hps -o bitstream_compression=on 
output_files/ghrd_10as066n2.sof output_files/ghrd_10as066n2.rbf

$ ls output_files/*.rbf
output_files/ghrd_10as066n2.core.rbf  output_files/ghrd_10as066n2.periph.rbf 

The command example listed above results in two new generated files: ghrd_10as066n2.core.rbf and ghrd_10as066n2.periph.rbf. These are the split .rbf files. The ghrd_10as066n2.periph.rbf must be loaded first, followed by the ghrd_10as066n2.core.rbf file.
