Why is the RPD endianness setting not loading correctly when loading a .cof file in the Intel® Quartus® Prime Standard or Lite Edition Software versions 18.0 and 18.1? - Why is the RPD endianness setting not loading correctly when loading a .cof file in the Intel® Quartus® Prime Standard or Lite Edition Software versions 18.0 and 18.1? Description Due to a known problem in Intel® Quartus® Prime Standard and Lite Edition Software versions 18.0 and 18.1, the RPD endianness setting is not properly reflected in the .cof file. It always defaults to little endian. Resolution As a workaround, use the command line alternative " quartus_cpf ." The syntax of creating a rpd file with a saved *.cof file is as follows: Execute quartus_cpf -c <cof file name>.cof <rpd file name>.rpd Custom Fields values: ['novalue'] Troubleshooting FB: 594825; False ['novalue'] ['FPGA Dev Tools Quartus® Prime Software QUARTUS-ALITE', 'FPGA Dev Tools Quartus® Prime Software Standard'] 19.1 18.0 ['Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
