alftp components missing in altera_mf_components on Quartus 20.1

    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

Wow. Thank you Frank!

That was the answer I was looking for. So sad that wasn’t given from Intel itself.

Where did you get the information that they were deprecated in favor of the HLS versions? I‘ve checked the update notes multiple times but haven’t stumbled upon that.

Greetings
