    Hi,

    Please modify the symbol properties & compile again,

    Right Click on symbol(LPM_DFF)-> properties-> Parameter as shown below,

    if this has not resolved then provide bit more information like,

    1. Quartus edition(Lite/Pro/Std) & Version used
    2. Device part number used
    3. Elaborate about, what exactly you are trying?

    Regards,

    Vicky

    Should I consider that case to be closed?

      Hi,

      Symbol synthesis will work,

      Can you try to convert the same symbol to VHDL and synthesis.

      regards,

    Hi Balakrishna,

    After successfully synthesis(my last post) , instantiate it in top module like below,

    1. Open .bdf file
    2. File-> Create/Update->Create VHDL component declaration component files for current file(It will create .cmp file)
    3. Open that .cmp file & instantiate it in top module & then compile that top module.

    Regards,

    Vicky
