    Hi all,

    I am trying to do a 64 bits operation. For that, i have wrote this line :

    type int64 is range 0 to 18446744073709551616

    But at compilation, its returns this following error :

    Integer value exceeds INTEGER'HIGH.

    I cant use signal because it's add too many latency that's why i must use 64 bits variable

    Thanks
