Hi , Bitgen generates as readback files ( .rba & .rbb) , but wich one contains exactly the data that is configured in the FPGA ? no one ?
M.B

" rba : An ASCII file that contains readback commands rather than configuration commands, and expected readback data where the configuration data would normally be. This file is only produced for Virtex/-E/Spartan-II/E devices.
.rbb -: (Produced when "-g Readback" is specified) - The same as the ".rba" file, but it is a binary file.
.rbd : (Produced when "-g Readback" is specified) - An ASCII file that contains only expected readback data, including pad words and frames. No commands are included."
