    Hi,


    ACCUMULATOR (ALT_ACCUM) Megafunction still exists in 13.0 version, in <quartus_installed_directory>/quartus/libraries/megafunctions/arithmetic/altaccumulate.bsf


    How to instantiate ACCUMULATOR (ALT_ACCUM) Megafunction in 13.0 version:

    1.You can either move the ACCUMULATOR (ALT_ACCUM) auto-generated .qip,and .v files from 9.0 version design to 13.0 version design and include the .qip file in 13.0 version design. Should be able to synthesis successfully.

    2.Create a .bdf file and then insert the ACCUMULATOR (ALT_ACCUM) Megafunction. Remember to connect both input and output signal in .bdf. After saving the .bdf file, go to File -> Create/Update -> Create HDL Design File from Current File


    Thanks,

    Best Regards,

    Sheng
