What are .rbf files and how can i generate them from the Quartus output file .sof on windows ?
With Quartus II GUI go to File => Convert Programming Files, where .rbf can then be selected as output file, and the .sof can be given as input file.
The conversion setup can be saved from the GUI for use in a command line like
> quartus_cpf -c convert_sof_to_rbf.cof
