    hi!
    i was trying to create a processor that could run at 32 or 64 bits
    for the 32 bits part, no problems
    however, while synthetising for the 64 one, it fails with
    Code:
    ERROR:Xst:808 - "rom.vhd" line 81: Argument of 'to_integer' function must have size less than 32.
    from what i understand, the to_integer function from numeric_std works with 32 bits vectors max!
    is there a way to make it accept 64 bits vectors?
    or is there some other function i should use?:hmm2:

    thanks a lot! :)
