Description
Due to a problem with the Reed-Solomon II Intel® FPGA IP core in the Intel® Quartus® Prime Pro Edition Software version 18.1, the error above will be seen if you have more than one instance of the Reed-Solomon II Intel® FPGA IP with the same module type but with different settings in your design.
Resolution
To work around this problem, copy the HEX files from the IP-generated HDL folders to the project directory and recompile your design.
