I have std_logic_vector passed to create XFER_SIZE and dwitdth. Not sure why the error is.

    Hi,

    I'm able to compile spi_if.vhd successfully on my side. Try go to Assignments/Settings/VHDL Input, makes sure VHDL 2008 is selected.

    Version: Quartus Prime Std 21.1

    Best regards,
    Sheng

    You can close this. I have global settings for VHDL 2008 compilation anyway. It turns out Quartus Std 2018 has the limitation to synthesize but 2019 Pro edition do not.
