As stated in a different thread, it's expected that you use the new HLS based FP_FUNCTIONS Intel FPGA IP instead. It has additional features like freely selecting the pipeline level based on speed requirements.

    Regards
    Frank

Hi Jan,


I received the reply from the team, you may create altera_fp_function in version 18.1 and use that instance in version 20.1. In v18.1, a qip file is also generated which will list all the generated files you need to include in your v20.1 project.


Thanks.

Best regards,
