    Hello,

    I came across the same problem today and noticed that the question hasn't been clearly answered by Intel team.

    The answer seems quite obvious though. All altfp_xxx IP has been removed from the library since Quartus 19 but is still in the IP catalog for some devices, curiously not for all, e.g. MAX10. 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

Is there any resolution to this other than use the ones from 18.1? I've found I cannot even open the MegaWizard for the IP that won't upgrade (ALTFP_MULT and ALTFP_CONVERT) that bails out without notice only leaving an "iplauncher_debug.log" file with the line "Fatal Error: The file altfp_mult_info.xml does not exist or cannot be read" It isn't clear from your answers, is this just an Intel " is not going to fix" thing?
