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? 

Environment

    Intel® Quartus® Prime Standard Edition
    Intel® Quartus® Prime Lite Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
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
