Why cannot configuration data size be reduced when enabling enhanced bitstream-compression? - Why cannot configuration data size be reduced when enabling enhanced bitstream-compression? Description Due to Quartus® problem, configuration bitstream size is not changed when turning on "Enable enhanced bitstream-compression when available" in Options of Convert Programming File when Programming file type set as Programmer Object File(.pof). You will see same data size in .map file. Start and end address of Page is same for both setting. You can successfully program the device with this pof file, but the configuration bitstream is not compressed.
